«La telefonía causa depresión, fatiga y desorden del sueño»

Entrevista | Claudio Gómez Perretta

Este experto es autor de un estudio de efectos sobre la salud que presentó ayer en la Universidade compostelana


Claudio Gómez Perretta, jefe de sección de Investigación en Salud Pública en el Hospital Universitario La Fe (Valencia), es autor de un estudio sobre la salud por la exposición crónica de radiofrecuencias provenientes de las estaciones base de telefonía móvil. Los detalles del informe fueron explicados en la conferencia pronunciada ayer por el investigador en la Facultad de Psicología.

-Los efectos sobre la salud de las personas son evidentes y claros. El síntoma central es la tendencia depresiva y, junto a éste, otros como la fatiga, desórdenes del sueño, irritabilidad y trastornos del apetito. Unos síntomas están ligados a otros.

¿Cuándo fue realizado el estudio?

Se hizo en el año 2003, en una pequeña localidad rural de Murcia, donde sólo hacía dos años que estaban sometidos a las emisiones electromagnéticas. Se analizó la situación de 144 personas, de las que el veinte por ciento usaban el móvil unos veinte minutos diarios. Los resultados fueron evidentes, y ello a pesar de que por entonces el número de estaciones de telefonía era menor a la situación actual. -Por lo que ahora los efectos son mayores. -Evidentemente. Pero, lamentablemente, aunque en dos ocasiones he intentado repetir los estudios para poder comprobar el nivel de afección actual, el Ministerio de Sanidad ha denegado en las dos ocasiones las ayudas económicas para llevarlo adelante.

¿A qué responde esta actitud?

Las autoridades sanitarias no tienen interés en este asunto. Son muy activos en otras cuestiones como el tabaco, pero la contaminación electromagnética no les preocupa. -Las empresas de telefonía móvil aseguran que no hay riesgo dentro de los límites marcados por la legislación. -En el estudio realizado en la localidad de La Ñora, en Murcia, la población estudiada estaba por debajo del límite aconsejado (0,1 microvatios por centímetro cuadrado) y los efectos fueron detectados. Es lógico que las empresas defiendan sus intereses económicos, pero lo que dicen no es cierto. La situación puede ser todavía peor. El sistema wi fi emite a 25 microvatios por centímetro cuadrado. Aquí en la Universidad hay determinados sitios donde se está expuesto a estos niveles de radiaciones.

Los niveles permitidos de ondas de telefonía móvil aumentan la tendencia depresiva, la fatiga y más

El ministerio de Sanidad actual no tienen interés en este asunto. Desde el año 2004 hasta ahora, ha denegado dos veces las ayudas para investigar los efectos de las ondas de telefonía móvil en la salud de las personas.

El jefe de Sección de Investigación en Salud Pública en el Hospital Universitario La Fe de Valencia, el doctor Claudio Gómez Perretta, aseguró el viernes día 28 que la exposición a microondas de telefonía móvil de intensidad muy baja incrementa "significativa y considerablemente" el padecimiento de fatiga, tendencia depresiva, desórdenes de sueño y de la piel, problemas cardiovasculares, dificultades de concentración y pérdida de apetito.

En una conferencia impartida en la Facultad de Psicología de Santiago de Compostela, Claudio Gómez Perretta expuso los resultados de un estudio epidemiológico del posible efecto sobre la salud por la exposición crónica de radiofrecuencias provenientes de las estaciones base de telefonía móvil.

El trabajo de campo fue realizado en dos estaciones base GSM de 900 y 1.800 megaherzios. El estudio abarcó a 97 personas de ambos sexos de edades comprendidas entre los 14 y 81 años y con una media de 39 años.

Gómez explicó que en los sujetos con un grado intermedio de exposición a las microondas se advirtieron cefaleas, náuseas, problemas de audición, irritabilidad, vértigo, alteraciones visuales y de la marcha, "en menor grado que los expuestos a mayores valores de flujo de densidad de potencia".

SÍNDROME DE MICROONDAS

Para la realización de la investigación, cada sujeto completó un cuestionario de síntomas "que comprenden el conjunto de aquellos que constituyen el síndrome de microondas", matizó el experto.

Según el nivel de exposición, medido en cada dormitorio de los participantes, se dividió la muestra en tres grupos: un primero de referencia con exposiciones de 0,0001 a 0,0004 microvatios por centímetro cuadrado; el intermedio con exposiciones de 0,0006 a 0,0128; y el de máximo, entre 0,0165 a 0,44.

A este respecto, el doctor Gómez Perretta apuntó que la ley permite hasta 450 microvatios por metro cuadrado para estaciones base de 900 megaherzios y de 900 microvatios por metro cuadrado para las de 1.800 megaherzios.

Gómez Perreta destaca por ser autor de un estudio pionero internacional sobre salud y exposición a microondas de las estaciones base de telefonía móvil. También es asesor de la Internacional Commission for Electromagnetic Safety (Icems) como miembro de pleno de la Sociedad Europea de Bioelectromagnetismo. [Este aspecto del currículum de Gómez Perreta lo omite Europa Press]

El doctor Claudio Gómez Perretta es licenciado en Medicina y en Ciencias Químicas por la Universidad de Valencia. Realizó estadías como becario de investigación en el Hospital Bichat de París y en el departamento de Psiquiatría del Down-State Medical Center de Nueva York.

Entre otras distinciones, obtuvo el Premio de Investigación Científica del Congreso Mundial para la Formación Profesional en 1997 y Premio de Investigación de la Sociedad Española de Toxicomanías en 1999, por sus aportaciones al estudio de la serotonina en la conducta auditiva.

Un estudio relaciona las antenas con la reducción en el número de gorriones
El biólogo Alfonso Balmorí denuncia que la radiacción electromagnética puede causar náuseas, dolores de cabeza e incluso insomnio

V. G. IZQUIERDO/VALLADOLID

El biólogo Alfonso Balmorí hizo público ayer un estudio con el que trata de demostrar la relación de causa efecto existente entre la desaparición «significativa» de la población de gorriones y la generalización de las instalaciones de antenas de telefonía móvil en la capital vallisoletana. El informe, publicado el pasado mes de abril en la revista especializada 'Electromagnetic Biology and Medicine', recoge un muestreo efectuado en una treintena de localizaciones de la ciudad entre octubre del 2002 y mayo del 2006 sobre el número de ejemplares de estas aves y la intensidad de las radiaciones electromagnéticas.

Las investigaciones efectuadas llevaron al biólogo a concluir que en aquellos puntos en los que se registró un mayor volumen de radiacciones es donde se contabiliza un descenso más acentuado de gorriones. En este sentido, Balmorí constató además que cuando se desmontaban estos aparatos, «los pájaros volvían a su lugar de origen».

Alfonso Balmorí, asesor científico de la asociación vallisoletana de Afectados por las Antenas de Telecomunicaciones, cuantificó en un 6% anual la disminución de gorriones en calles como Miguel Íscar o en plazas como Las Brígidas o Portugalete desde que comenzara sus indagaciones. Más preocupante es la situación del entorno del Campo Grande, parque en el que la población de estos pájaros se ha reducido a la mitad. Especies de aves como los agateadores o como los picos carpinteros han llegado a desaparecer de este emplazamiento por esta causa, según explica el biólogo.

Los estudios realizados en esta materia dejan «prácticamente demostrados» los efectos de las radiacciones de las antenas sobre las personas, que se traducen en nauseas, insomnio y cefaleas.

Salud y Antenas Móviles - El experimento biológico más grande de la historia

La mayoría de los sistemas Wi-Fi y algunos teléfonos sin cables radian exactamente a la misma frecuencia que un horno a microondas. Las bases de la mayoría de los teléfonos sin cable siempre están irradiando, incluso cuando nadie está utilizando el teléfono. Un teléfono móvil que está encendido, aunque no esté en uso, también está irradiando. Y, no hace falta decirlo, las antenas de los inmuebles están siempre irradiando.


En 2002, Gro Harlem Brundtland, por entonces responsable de la OMS, le dijo a un periodista noruego que los teléfonos celulares fueron prohibidos en su oficina en Ginebra porque ella personalmente sufría malestar cada vez que un teléfono celular se acercaba a menos de cuatro metros de ella. Mrs. Brundtland es médico y fue Primer Ministro de Noruega. Esta sensacional noticia publicada el 9 de marzo, 2002 en Dagbladet, fue ignorada por todos los periódicos del mundo.


A la semana siguiente Michael Repacholi, su subordinado a cargo del Proyecto Internacional CEM (campos electromagnéticos), respondió con una declaración pública minimizando las preocupaciones de su superiora. Cinco meses después, por razones que pueden suponerse relacionadas con esas circunstancias, Mrs. Brundtland anunció que renunciaría a su puesto en la OMS después de un solo período. Nada puede ilustrar mejor nuestra esquizofrenia colectiva cuando se trata de pensar sobre radiaciones electromagnéticas. Respondemos a aquellos que están preocupados sobre los peligros -una vez más el Proyecto Internacional CEM- pero ignoramos y marginamos a aquellos que, como Mrs. Brundtland, ya han sucumbido a sus efectos.


Como consultor de los efectos en la salud producidos por la tecnología inalámbrica, recibo consultas que pueden ser divididos en dos grandes grupos: las de personas que están simplemente preocupadas, a las cuales denomino A y aquellas que ya están enfermas, y que denomino B. Algunas veces desearía poder organizar una gran conferencia y hacer que los dos grupos hablen entre sí. Es necesaria más comunicación ya que todos estamos intentando resolver los mismos problemas.


La persona A, preocupada, generalmente pregunta qué tipo de protección comprar para su teléfono celular o qué tipo de auricular utilizar. Algunas veces quiere saber cuál es la distancia segura de una antena para vivir. La persona B, enferma, quiere saber qué tipo de protección poner en su casa, qué tipo de tratamiento médico seguir, o, cada vez más frecuente, a qué parte del país debería mudarse para escapar de la radiación y salvar su vida. Lo que sigue está diseñado para ayudar en primer lugar a que todos más o menos tengan un mínimo de información y, segundo, para aclarar algunas dudas de modo que podamos tomar racionales para una vida más saludable.


1.- Principios básicos.


Los hechos más básicos sobre teléfonos y antenas celulares es que emiten radiación de microondas; también lo hacen las antenasWi-Fi (Internet inalámbrico), ordenadores inalámbricas, teléfonos sin cable (portátiles) y sus bases, como así también todos los demás dispositivos inalámbricos. Si es un aparato para comunicaciones y no está fijado a la pared por un cable, está emitiendo radiación.


La mayoría de los sistemas Wi-Fi y algunos teléfonos sin cables radian exactamente a la misma frecuencia que un horno a microondas, mientras que otros dispositivos utilizan una frecuencia diferente. Wi-Fi está siempre encendido y siempre está irradiando. Las bases de la mayoría de los teléfonos sin cable siempre están irradiando, incluso cuando nadie está utilizando el teléfono. Un teléfono móvil que está encendido, aunque no esté en uso, también está irradiando. Y, no hace falta decirlo, las antenas de los inmuebles están siempre irradiando.


¿Por qué esto es un problema? Los científicos generalmente dividen el espectro electromagnético en “ionizante” y “no-ionizante”. La radiación ionizante, la cual incluye rayos x y radiación atómica, causa cáncer. La radiación no-ionizante, que incluye radiación de microondas, se supone que es segura.


Esta distinción siempre me recuerda la propaganda en "Animales en la Granja” de George Orwell: “Cuatro patas bueno, dos patas malo”. “No-ionizante bueno, ionizante malo” es muy poco creíble.


Un astrónomo una vez bromeó que si Neil Armstrong hubiera llevado un teléfono celular a la Luna en 1969, hubiera aparecido como la tercera fuente de radiación de microondas más poderosa del universo, al lado del Sol y La Vía Láctea. Él tenía razón. La vida evolucionó con niveles insignificantes de radiación de microondas. Un número cada vez mayor de científicos especulan que nuestras propias células, de hecho, usan las microondas para comunicarse entre sí, igual que niños susurrando en la oscuridad y que los teléfonos celulares, igual que martillos neumáticos, interfieren con sus señales. En cualquier caso, es un hecho que estamos siendo bombardeados, día y noche, ya sea que utilicemos un teléfono celular o no, por una cantidad de radiación de microondas que es diez millones de veces más fuerte que el entorno promedio natural.


Es un hecho que mucha de la radiación es debida a tecnología que se ha estado desarrollando desde la década del 70. Mientras que los mismos teléfonos celulares producen preocupación; si se coloca uno en la oreja está dañando su cerebro de diferentes maneras:


El calentamiento

Primero, piense en un horno-microondas. Un teléfono celular, igual que un horno microondas y a diferencia de una ducha caliente, le calienta a usted el cerebro de adentro hacia fuera y no de afuera hacia dentro. Y no hay terminaciones nerviosas en el cerebro para advertirle que se está calentando porque no hemos evolucionado con radiaciones de microondas y la naturaleza no ha creado en el cerebro terminaciones nerviosas que detecten el calor. Peor aún, la estructura de la cabeza y el cerebro es tan compleja y no uniforme que se generan "puntos calientes", donde uno de ellos pueden estar decenas o centenares de veces mas caliente que en otro punto adyacente. Los puntos calientes pueden estar cerca de la superficie del cráneo o muy dentro del cerebro, como también a nivel molecular.


Los teléfonos celulares son regulados por la Federal Communications Comisión (FCC) y usted puede encontrar en el embalaje de muchos teléfonos nuevos, un número llamado el Specific Absorption Rate, o SAR, el cual sirve indicar la tasa de energía que es absorbida por el cerebro con el uso del móvil. Un problema, sin embargo, es la suposición arbitraria sobre la cual se basan las regulaciones de la FCC, en que el cerebro puede disipar de manera segura el aumento del calor a una tasa de hasta 1 grado por hora. Éste es el escandaloso procedimiento utilizado para demostrar que se está dentro de esos límites y darle a cada teléfono celular su calificación SAR.


La manera estándar para medir el SAR (tasa de energía absorbida) es un "método-fantasma" que consiste, increíblemente, en un líquido homogéneo metido en una bolsa de Plexiglas (un plástico) con la forma de cabeza. Pero en esa bolsa, como en la cabeza, ¡no hay puntos calientes! Se calienta todo por igual. Las personas que utilizan teléfonos móviles durante horas diariamente están calentando crónicamente ciertos lugares o puntos de sus cerebros. El estándar de seguridad creado por la FCC, dicho sea de paso, fue desarrollado por ingenieros eléctricos, no por médicos.


La Barrera hematoencefálica

El segundo efecto en el cual quiero concentrarme, ha sido demostrado en el laboratorio, debería ser por sí mismo suficiente para cerrar ésta industria y para desaconsejar a cualquiera usar un teléfono móvil.


Yo le llamo el "revólver humeante" de los experimentos de teléfonos móviles. Como muchos efectos biológicos de radiaciones de microondas, este no tiene nada que ver con el calor. El cerebro está protegido por apretadas uniones entre células adyacentes con paredes capilares, la llamada Barrera hematoencefálica, la cual, igual que una patrulla fronteriza, permite que pasen solo los nutrientes de la sangre al cerebro, pero mantiene alejadas las sustancias tóxicas. Desde 1988, las investigaciones en el laboratorio de un neurocirujano sueco, Leif Salford, han consistido en exponer a jóvenes ratas de laboratorio ante un teléfono móvil o a otra fuente de radiación de microondas; luego sacrifica a los animales y buscan la albúmina en su cerebro. La albúmina es una proteína que es un componente normal de la sangre pero que normalmente no cruza la barrera hematoencefálica que protege el cerebro. La presencia de albúmina en el tejido cerebral siempre es señal de que las venas han sido dañadas y de que el cerebro ha perdido parte de su protección. Esto es lo que los investigadores han encontrado, consistentemente durante 18 años.


Las radiaciones de microondas, en dosis iguales a las emisiones de los teléfonos celulares, provocan que se encuentre albúmina en el tejido cerebral. Una simple exposición a un teléfono celular común durante dos minutos hace que la albúmina pase al cerebro. En un conjunto de experimentos, redujeron el nivel exposición en un factor de 1,000 el aumento del daño de la barrera sanguínea cerebral, mostrando que no es el efecto de respuesta a una dosis y que reducir la potencia no hará que la tecnología inalámbrica sea más segura.


Y finalmente, en una investigación publicada en junio 2003, una simple exposición de dos horas a un teléfono móvil permanentemente dañó la barrera sanguínea cerebral y, en un autopsia 50 días más tarde, se encontró que había dañado o destruido hasta el 2 por ciento de las células del cerebro de un animal, incluyendo células en un área del cerebro relacionada con el aprendizaje, memoria y movimiento. Reducir el nivel de exposición por un factor de 10 o 100, de este modo, duplicando el efecto de utilizar un “manos libres”, mover un teléfono celular más lejos de su cuerpo, o estando cerca del teléfono de otra persona, ¡no cambió apreciablemente los resultados! Incluso en la exposición más baja, la mitad de los animales tenían un número de moderado a alto de neuronas dañadas.


¿Qué supone esto para nosotros? Dos minutos de un teléfono celular trastornan la Barrera hematoencefálica cerebral, dos horas en un teléfono celular causar un daño cerebral permanente y las radiaciones del vecino que habla por teléfono pueden ser igual de perjudiciales. La Barrera hematoencefálica es la misma en una rata que en un ser humano. Esos resultados causaron tanta conmoción en Europa que en noviembre de 2003 se celebró una conferencia, auspiciada por la Unión Europea, titulada “The Blood-Brain Barrier - Can It Be Influenced by RF [radio frequency]-Field Interactions?” (¿Pueden afectar las microondas a la barrera sanguínea del cerebro?) para demostrar al público que se está haciendo algo. Pero, previsiblemente, nada se hizo, como nada se ha estado haciendo durante 30 años.


Allan Frey de Estados Unidos, durante años 70, fue el primero en demostrar que la radiación de microondas de bajo nivel daña la Barrera hematoencefálica. Mecanismos similares protegen el ojo (la barrera sanguínea vitrosa) y el feto (la barrera de la placenta). Los trabajos de Frey y otros indican que las radiaciones de microondas dañan también esas barreras. Consecuencias: ninguna mujer embarazada debería utilizar un teléfono móvil. El Dr. Salford es bastante claro en su trabajo. Él ha denominado al uso de teléfonos celulares “el experimento biológico más grande jamás realizado.” Y ha advertido públicamente que toda una generación de adolescentes usuarios de teléfonos celulares puede sufrir déficit mental o enfermedad de Alzheimer a una edad temprana.


2.- Enfermedades de las radiofrecuencias o síndrome de microondas.


Desafortunadamente, los usuarios de teléfonos móviles no son los únicos que afectados, ni tampoco deben estar preocupados solamente por el cerebro. El siguiente resumen está inspirado en una amplia literatura científica sobre los efectos de ondas de radio (un espectro más grande el cual incluye las microondas) junto con las experiencias de científicos y doctores de todo el mundo con los cuales estoy en contacto.


Los órganos que han mostrado ser especialmente susceptibles a la radiación incluyen los pulmones, sistema nervioso, corazón, ojos, testículos y glándula tiroidea.


Las enfermedades también han aumentado significativamente en las últimas dos décadas, y hay una buena razón para relacionarlo con el masivo aumento de la radiación en nuestro entorno; el asma, desórdenes del sueño, desórdenes de ansiedad, trastornos de déficit de atención, autismo, esclerosis múltiple, ALS, enfermedad de Alzheimer, epilepsia, fibromialgia, síndrome de fatiga, cataratas, hipotiroidismo, diabetes, melanoma maligno, cáncer testicular, y ataques cardiacos e infartos en gente joven. La radiación de torres de antenas de microondas también ha sido asociada con la muerte de bosques, fallos en la reproducción y disminución de la población de muchas especies de pájaros y deformidades de nacimiento en animales de granja.


La literatura que muestra los efectos biológicos de la radiación de microondas es realmente enorme, de decenas de miles de documentos, y estoy asombrado de que los representantes de la industria afirmen que la tecnología inalámbrica es segura o - igual de ridículo- que no hay evidencia de daños.


He omitido una enfermedad de la lista anterior: la enfermedad que tiene la persona B y que yo también tengo: electrosensibles. Viene ahora a cuento una breve historia. En los años 50 y 60 los trabajadores que construyeron, inspeccionaron y repararon equipos de radar contrajeron esta enfermedad en gran número. También lo hicieron los operadores de calentadores y selladores industriales de microondas. Los soviéticos lo denominaron, apropiadamente, enfermedad de las radiofrecuencias (electrosensibiloidad) y lo estudiaron de manera muy amplia. En los países occidentales su existencia fue negada totalmente, sin embargo los trabajadores enfermaron. Los testimonios en el congreso en 1981, presididos por el entonces representante Al Gore, sobre los efectos en la salud de calentadores y selladores de radiofrecuencia, fueron otro episodio para tranquilizar como que se estaba haciendo algo al respecto”.


Hoy, con la proliferación en masa de antenas, torres de radio y transmisores personales, la enfermedad se ha expandido como una plaga en la población en general. Se estima que puede llegar a abarcar hasta un tercio de la población, pero raramente se lo reconoce hasta que ha discapacitado tanto a una persona que él o ella ya no puede participar más en sociedad. Usted puede reconocer alguno de sus síntomas comunes: insomnio, vértigo, náusea, dolores de cabeza, fatiga, pérdida de memoria, incapacidad para concentrarse, depresión, malestar en el pecho, zumbidos en los oídos. Los pacientes pueden también haber desarrollado problemas médicos tales como infecciones respiratorias crónicas, arritmias cardiacas, repentinas fluctuaciones en la presión sanguínea, azúcar en la sangre descontrolada, deshidratación e incluso sangrado interno espontáneo.


Lo que hace esta enfermedad que sea tan difícil de aceptar, e incluso más difícil de manejar, es que ningún tratamiento probablemente tenga éxito a menos que uno pueda también evitar la exposición a su causa- y su causa ahora está en todas partes.


Una investigación de 1998 por el California Department of Health Services (Departamente del Servicio de la Salud) indicó que en ese momento 120,000 californianos -y por lo tanto 1 millón de estadounidenses- no podían trabajar debido a la polución electromagnética. Los porcentajes de los así llamados electrosensibles están aumentando en casi todos los países del mundo, marginados, estigmatizados e ignorados. Con el nivel de radiación en todos lados actualmente, nunca se recuperan y a veces acaban con sus propias vidas. “Ellos están actuando como una advertencia para todos nosotros,” dice Dr. Olle Johansson de personas con esta enfermedad. “Podría ser un gran error someter a toda la población mundial a una irradiación de todo el cuerpo, las 24 horas al día”. Un neurocientífico en el famoso Karolinska Institute en Estocolmo, Dr. Johansson dirige un equipo de investigación que está documentando un empeoramiento permanente y significativo de la salud pública que comenzó precisamente cuando la segunda generación, de teléfonos celulares de 1800 MHz se presentaron en Suecia a fines de 1997. Después de una larga década de descenso, el número de trabajadores suecos enfermos comenzó a aumentar a fines de 1997 y se ha más que duplicado durante los siguientes cinco. Durante el mismo periodo de tiempo, las ventas de drogas antidepresivas también se duplicaron. El número de accidentes de tráfico, después de disminuir durante años, comenzó a aumentar de nuevo en 1997. El número de muertes de la enfermedad de Alzheimer, después de disminuir durante algunos años, aumentó bruscamente en 1999 y casi se ha duplicado para 2001. Esta demora de dos años es entendible cuando uno considera que la enfermedad de Alzheimer requiere algún tiempo para desarrollarse.


3.- Proliferación descontrolada


Si los teléfonos móviles y las antenas son realmente mortales, ¿son seguras las torres de radio-televisión con las que hemos estado viviendo durante un siglo? En 2002 Örjan Hallberg y Olle Johansson escribieron en conjunto un trabajo titulado “Cáncer Trends During the 20th Century,” (Tendencia al cáncer en el siglo XXI) el cual examinó un aspecto de esa pregunta. Encontraron en los Estados Unidos, Suecia y varios otros países, que las tasas de mortalidad por melanoma de piel y cáncer de vejiga, próstata, colon, mama y pulmones seguían estrechamente al nivel de exposición pública a ondas de radio durante los últimos 100 años. Cuando la transmisión de radio aumentó en una localidad determinada, también lo hicieron algunas formas de cáncer; cuando disminuyeron, también lo hicieron esas formas de cáncer. Y, un descubrimiento sensacional: país por país - y región por región en Suecia, hallaron, estadísticamente, que la exposición a ondas de radio ¡parece ser un factor tan importante en causar cáncer de pulmón como fumar tabaco! Lo cual me lleva a señalar una concepción errónea ampliamente difundida.


La mayor diferencia entre las antenas de telefonía de hoy y las antenas de radio del pasado no es su seguridad sino su número. El número de estaciones de radio ordinarias en los Estados Unidos actualmente es menos de 14,000. Pero el número de antenas de móviles y Wi-Fi (sin cable) se cuenta por centenares de miles y los teléfonos móviles, ordenadores inalámbricos, teléfonos sin cable y radios de dos vías alcanzan los centenares de millones. Los radares y las redes de comunicación de emergencia también están proliferando fuera de control. Desde 1978, cuando la Environmental Protection Agency (Departamente de Protección del Medio Ambiente) revisó por última vez el entorno de radiofrecuencia en los Estados Unidos, la exposición promedia del habitante urbano a las ondas de radio ha aumentado 1000 veces; mucho de este incremento ocurrió solamente en los últimos nueve años.


En el mismo periodo de tiempo, la polución de las ondas de la radio se ha esparcido desde las ciudades al resto como una niebla omnipresente sobre todo el planeta. Las vastas consecuencias humanas de todo esto han sido ignoradas.Desde finales de los 90 se ha creado una nueva clase completamente nueva de refugiados ambientales aquí en los Estados Unidos. Tenemos cada vez más personas, enfermas, muriendo, buscando alivio de este sufrimiento, abandonando los hogares y puestos de trabajo, viviendo en coches, módulos y tiendas en lugares alejados.


A diferencia de las víctimas de huracanes y terremotos, no somos objeto de ningún esfuerzo de ayuda humanitaria. Nadie está donando dinero para ayudarnos, para facilitarnos un refugio protegido; nadie está renunciando a sus teléfonos móviles, a sus ordenadores inalámbricos, a sus teléfonos sin cable de modo que podamos ser de nuevo sus vecinos y vivir entre ellos. Los afectados, los enfermos, todavía no han abierto sus corazones entre ello, pero están haciendo preguntas.


Para responder a la persona A (que se preocupa por los efectos): Ningún método de manos libres le protegerá de su móvil o teléfono portátil. No hay una distancia segura respecto una antena. Si su teléfono móvil u ordenador inalámbrico está activo donde usted vive, usted está siendo irradiado las 24 horas del día.


Para la persona B (enferma): Proteger efectivamente una casa es difícil y pocas veces eficaz. Hay solamente unos pocos doctores en los Estados Unidos intentando tratar la enfermedad de las ondas de radio y su efectividad es pobre, porque hay pocos lugares que quedan en la tierra donde uno puede escaparse de esta radiación y recuperarse. Si la radiación baja de los satélites, también son parte del problema, no la solución. Simplemente no hay manera de hacer la tecnología inalámbrica segura.

Electronic smog linked to respiratory disease[B], study shows
By Geoffrey Lean, Environment Editor
Published: 29 July 2007

Electrical fields from computers, televisions and other everyday equipment can give people asthma, influenza and other respiratory diseases, a startling new study suggests.
The research, by scientists at Imperial College London, provides academic backing for one of the more controversial claims of campaigners against the thickening electro-smog from sources such as mobile phones and their masts, Wi-Fi systems and household electrical devices.
The scientists believe that there should now be research into whether electromagnetic radiation from sources such as mobile phone masts and Wi-Fi systems has the same effect.
The study is bound to increase the row over the effects of the electro-smog. It comes in the wake of the publication last week of research which concluded that people who believe that the masts are making them ill are deluding themselves. This research, by psychologists at Essex University, found that people who claimed to be sensitive to radiation from the masts could not tell when they were being subjected to them. It has, however, been criticised for alleged flaws and for measuring only short-term exposure.
MPs are to consider the health effects of the masts and Wi-Fi systems in an adjournment debate called by the Liberal Democrats' local government spokesman, Tom Brake, in October.
Suspicion that electrical fields cause respiratory illness dates back to the 1950s when it was found that placing asthmatics in areas with low electrical fields got rid of their symptoms. As the amount of electro-smog has multiplied many fold since then, campaigners have increasingly insisted that it causes a wide range of ailments, from respiratory diseases to difficulties in concentrating, from sleeplessness to cancer.
[B]The research by Imperial College's Centre for Environmental Policy – which will be published in the August issue of the journal Atmospheric Environment – provides powerful evidence of how respiratory diseases may be caused.

The scientists found that the electrical fields given off by a wide variety of household items, including compu-ters, televisions, cookers, lamps and even wiring, charge minuscule particles in the air such as viruses, bacteria, allergens and highly toxic pollutants.
Because they are so tiny – less than 80 times the thickness of a human hair – they are constantly airborne and so are being breathed in all the time. The electrical charge makes them stick to the tissue of the lungs and respiratory tract, causing infection and increasing the impact on the body.
The higher the electrical field the greater the danger, as the most charged particles hit the tissue with more speed. As they crash land, they become deformed, which makes them stick more firmly.
Electrostatic charges, such as those given off by clothing and sheets made of synthetic materials, add to the problem.
The research also shows that the electrical fields greatly reduced concentrations of charged molecular oxygen, which is readily absorbed by the body, enhances biological functions and can also kill harmful microbes.
Keith Jamieson, who led the research, is particularly worried about the effects in hospitals, where already sick people are surrounded by electrical equipment and often have sheets made of synthetic materials.
He adds, however, that, "there are a number of easy actions which can be implemented in the home and workplace to help reduce the toxic load on our bodies and the risk of illness and infection".
He said that people should ensure that electrical equipment – particularly laptop computers – is earthed, avoid synthetic materials, and unplug equipment when it is not in use.

Radio towers linked to leukaemia
Children who live close to an AM radio transmission tower may have an elevated risk of leukaemia, a study suggests.

South Korean researchers found that children who lived within 2 kilometres (about 1-1/4 miles) of an AM radio transmitter were twice as likely to develop lymphocytic leukaemia as children who lived more than 20 kilometres (approximately 12-1/2 miles) away.
There was no such link found for childhood brain cancer or any cancer in babies, according to the researchers, led by Dr Mina Ha of Dankook University College of Medicine.

The findings, published in the American Journal of Epidemiology, add to the conflicting body of research on electromagnetic fields (EMFs) and cancer. EMFs are emitted by a wide variety of sources, like home appliances, cell phones, power lines and radio and TV transmission towers.

Mixed findings

Researchers have found limited evidence that living close to power lines might be a risk factor for childhood leukaemia. Studies on the possible health risks of radio and TV towers have produced mixed findings, according to Ha's team.
For their study, the researchers attempted to get a more accurate assessment of the relationship between children's exposure to radio wave energy and their risks of leukaemia and brain cancer - the two most common childhood cancers.
The researchers took measurements of the electric and magnetic fields surrounding AM transmission towers in various areas of South Korea, and used a mathematical model to estimate nearby residents' exposure to radiation from the towers.
The study included 1 928 children with leukaemia, 956 with brain cancer and 3 082 healthy children. Ha's team found that children who lived less than two miles from a radio tower were twice as likely to have lymphocytic leukaemia than those who lived more than a dozen miles away.

Up to 59% increased risk

Similarly, when the researchers looked at estimated exposure to radiation from the towers, children with the least exposure had the lowest leukaemia risk. The risk was 39 percent higher for those with intermediate exposure, and 59 percent greater for those with the highest exposure.
The results, Ha's team concludes, "suggest a possible carcinogenic effect" of energy from AM radio towers. However, they say more research is needed to confirm the findings, and to figure out the biological mechanisms that may be at work.

The Hidden Dangers of Cell Phone Radiation
By Sue Kovach


Every day, we’re swimming in a sea of electromagnetic radiation (EMR) produced by electrical appliances, power lines, wiring in buildings, and a slew of other technologies that are part of modern life. From the dishwasher and microwave oven in the kitchen and the clock radio next to your bed, to the cellular phone you hold to your ear—sometimes for hours each day—exposure to EMR is growing and becoming a serious health threat.

But there’s a huge public health crisis looming from one particular threat: EMR from cellular phones—both the radiation from the handsets and from the tower-based antennas carrying the signals—which studies have linked to development of brain tumors, genetic damage, and other exposure-related conditions.1-9 Yet the government and a well-funded cell phone industry media machine continue to mislead the unwary public about the dangers of a product used by billions of people. Most recently, a Danish epidemiological study announced to great fanfare the inaccurate conclusion that cell phone use is completely safe.10

George Carlo, PhD, JD, is an epidemiologist and medical scientist who, from 1993 to 1999, headed the first telecommunications industry-backed studies into the dangers of cell phone use. That program remains the largest in the history of the issue. But he ran afoul of the very industry that hired him when his work revealed preventable health hazards associated with cell phone use.

In this article, we look at why cell phones are dangerous; Dr. Carlo’s years-long battle to bring the truth about cell phone dangers to the public; the industry’s campaign to discredit him and other scientists in the field; and what you can do to protect yourself now.

Cell Phones Reach the Market without Safety Testing
The cellular phone industry was born in the early 1980s, when communications technology that had been developed for the Department of Defense was put into commerce by companies focusing on profits. This group, with big ideas but limited resources, pressured government regulatory agencies—particularly the Food and Drug Administration (FDA)—to allow cell phones to be sold without pre-market testing. The rationale, known as the “low power exclusion,” distinguished cell phones from dangerous microwave ovens based on the amount of power used to push the microwaves. At that time, the only health effect seen from microwaves involved high power strong enough to heat human tissue. The pressure worked, and cell phones were exempted from any type of regulatory oversight, an exemption that continues today. An eager public grabbed up the cell phones, but according to Dr. George Carlo, “Those phones were slowly prompting a host of health problems.”

Today there are more than two billion cell phone users being exposed every day to the dangers of electromagnetic radiation (EMR)—dangers government regulators and the cell phone industry refuse to admit exist. Included are: genetic damage, brain dysfunction, brain tumors, and other conditions such as sleep disorders and headaches.1-9 The amount of time spent on the phone is irrelevant, according to Dr. Carlo, as the danger mechanism is triggered within seconds. Researchers say if there is a safe level of exposure to EMR, it’s so low that we can’t detect it.

The cell phone industry is fully aware of the dangers. In fact, enough scientific evidence exists that some companies’ service contracts prohibit suing the cell phone manufacturer or service provider, or joining a class action lawsuit. Still, the public is largely ignorant of the dangers, while the media regularly trumpets new studies showing cell phones are completely safe to use. Yet, Dr. Carlo points out, “None of those studies can prove safety, no matter how well they’re conducted or who’s conducting them.” What’s going on here? While the answer in itself is simplistic, how we got to this point is complex.

Flawed Danish Study Reports Cell Phones are Safe

In December, 2006, an epidemiological study on cell phone dangers published in the Journal of the National Cancer Institute sent the media into a frenzy.10 Newspaper headlines blared: “Danish Study Shows Cell Phone Use is Safe,” while TV newscasters proclaimed, “Go ahead and talk all you want—it’s safe!” The news seemed to be a holiday gift for cell phone users. But unfortunately, it’s a flawed study, funded by the cell phone industry and designed to bring a positive result. The industry’s public relations machine is working in overdrive to assure that the study get top-billing in the media worldwide.

According to Dr. George Carlo, the study, by its design, could not identify even a very large risk. Therefore, any claim that it proves there’s no risk from cell phones is a blatant misrepresentation of the data that will give consumers a very dangerous false sense of security.

“Epidemiological studies are targets for fixing the outcome because they’re observational in nature instead of experimental,” Dr. Carlo explains. “It’s possible to design studies with pre-determined outcomesthat still fall within the range of acceptable science. Thus, even highly flawed epidemiological studies can be published in peer-reviewed journals because they’re judged against a pragmatic set of standards that assume the highest integrity among the investigators.”

Key problems with the study are:

There are few discernable differences between who was defined as cell phone users and who wasn’t. Thus, people defined as exposed to radiation were pretty much the same as those defined as not exposed to radiation. With few differences, it’s nearly impossible to find a risk.

Users were defined as anyone who made at least one phone call per week for six months between 1982 and 1995. So any person who made 26 calls was a cell phone user and therefore considered exposed to radiation. Those with less than 26 calls were non-users. In reality, the radiation exposure between users and non-users defined in this manner is not discernable.

The “exposed” people used ancient cell phone technology bearing little resemblance to cell phones used today. The results, even if reliable, have no relevance to the 2 billion cell phone users today.

From 1982 to 1995, cell phone minutes cost much more than today and people used their phones much less. Thus there was very little radiation exposure.

During the study’s time frame, people likely to use their cell phones the most were commercial subscribers. Yet this highest exposed group, in whom risk would most easily be identified, was specifically excluded from the study.

There were no biological hypotheses tested in the study. It was therefore only a numbers game. Ignored were mechanisms of disease found in other studies of cell phone radiation effects, including genetic damage, blood-brain barrier leakage, and disrupted intercellular communication. The study did not discuss any research supporting the notion that cell phones could cause problems in users.

The study itself was inconsistent with cancer statistics published worldwide addressing the Danish population. This study showed a low risk of cancer overall, when in fact Denmark has some of the highest cancer rates in the world. This inconsistency suggested that something in the data does not add up.

The cell phone industry constantly guards its financial interests, but unfortunately, an unwitting public can be harmed in the process, says Dr. Carlo. “Industry-funded studies in many cases now produce industry-desired outcomes. By tampering with the integrity of scientists, scientific systems and public information steps over the lines of propriety that are appropriate for protecting business interests—especially when the casualty of the interference is public health and safety.”

Lawsuit Prompts Safety Studies

In 1993, the cell phone industry was pressured by Congress to invest $28 million into studying cell phone safety. The cause of this sudden concern was massive publicity about a lawsuit filed by Florida businessman David Reynard against cell phone manufacturer NEC. Reynard’s wife, Susan, died of a brain tumor, and he blamed cell phones for her death. Reynard revealed the suit to the public on the Larry King Live show, complete with dramatic x-rays showing the tumor close to where Susan held her cell phone to her head for hours each day.

The next day, telecommunications stocks took a big hit on Wall Street and the media had a field day. The industry trade association at the time, the Telecommunications Industry Association (TIA), went into crisis mode, claiming thousands of studies proved cell phones were safe and what Reynard and his attorney said was bunk. TIA reassured the public that the government had approved cell phones, so that meant they were safe. The media demanded to see the studies, but, says Dr. Carlo, “The industry had lied. The only studies in existence then were on microwave ovens. At that time, 15 million people were using cell phones, a product that had never been tested for safety.”

Dr. Carlo Heads Cell Phone Research
Cell Phone Radiation: What You Need to Know


Originally developed for the Department of Defense, cell phones devices were never tested for safety. They entered the marketplace due to a regulatory loophole.

Questions about cell phone safety arose in the early 1990s, when a businessman filed a lawsuit alleging that cell phones caused his wife’s death due to brain cancer.

To address the questions surrounding cell phone safety, the cell phone industry set up a non-profit organization, Wireless Technology Research (WTR). Dr. George Carlo was appointed to head WTR’s research efforts.

Under Dr. Carlo’s direction, scientists found that cell phone radiation caused DNA damage, impaired DNA repair, and interfered with cardiac pacemakers.

European research confirmed Dr. Carlo’s findings. Studies suggest that cell phone radiation contributes to brain dysfunction, tumors, and potentially to conditions such as autism, attention deficit disorder, neurodegenerative disease, and behavioral and psychological problems.

Dr. Carlo brought safety information about cell phones to the public through his book, Cell Phones: Invisible Hazards in the Wireless Age, and by creating the Safe Wireless Initiative and the Mobile Telephone Health Concerns Registry.

The best protection against cell phone radiation is keeping a safe distance.

Always use a headset to minimize exposure to harmful cell phone radiation.

Forced to take action, the cell phone industry set up a non-profit organization, Wireless Technology Research (WTR), to perform the study. Dr. Carlo developed the program outline and was asked to head the research. Oversight of the issue was charged to the FDA, though it could have and probably should have gone to the Environmental Protection Agency (EPA), which fought hard for jurisdiction. But the industry had enough influence in Washington to get whatever overseer it wanted. It simply didn’t want to tangle with EPA because, says Dr. Carlo, “… the EPA is tough.”

“Anything that’s ever made a difference in terms of public health has come from the EPA,” he says. “But safety issues that are covered in corruption and questions seem to always have a connection to the FDA, which has been manipulated by pharmaceutical companies since it was born.”

When called to help with the cell phone issue, Dr. Carlo was working with the FDA on silicone breast implant research. The choice of Dr. Carlo to head WTR seemed unusual to industry observers. An epidemiologist whose expertise was in public health and how epidemic diseases affect the population, he appeared to lack any experience in researching the effects of EMR on human biology. Based on this, a premature conclusion was drawn by many: Dr. Carlo was an “expert” handpicked by the cell phone industry, and therefore his conclusions would only back up the industry’s claim that cell phones are safe.

Dr. Carlo, however, refused to be an easy target. He quickly recruited a group of prominent scientists to work with him, bulletproof experts owning long lists of credentials and reputations that would negate any perception that the research was predestined to be a sham. He also created a Peer Review Board chaired by Harvard University School of Public Health’s Dr. John Graham, something that made FDA officials more comfortable since, at the time, the agency was making negative headlines due to the breast implant controversy. In total, more than 200 doctors and scientists were involved in the project.

Strict Study Guidelines

Once all involved agreed on what was to be done, Dr. Carlo presented the study’s stakeholders in the industry, the government, and the public with a strict list of criteria for moving forward.

“The money had to be independent of the industry—they had to put the money in trust and couldn’t control who got the funds,” he says. “Second, everything had to be peer reviewed before it went public, so if we did find problems after peer review, we could use that information publicly to recommend interventions.”

A third requirement was for the FDA to create a formal interagency working group to oversee the work and provide input. The purpose of this was to alleviate any perception that the industry was paying for a result, not for the research itself. But the fourth and last requirement was considered by Dr. Carlo to be highly critical: “Everything needed to be done in sunlight. The media had to have access to everything we did.”

The Research Begins

The program began, but Dr. Carlo soon discovered that everyone involved had underlying motives.“The industry wanted an insurance policy and to have the government come out and say everything was fine. The FDA, which looked bad because it didn’t require pre-market testing, could be seen as taking steps to remedy that. By ordering the study, law makers appeared to be doing something. Everyone had a chance to wear a white hat.”

Dr. Carlo and his team developed new exposure systems that could mimic head-only exposure to EMR in people, as those were the only systems that could approximate what really happened with cell phone exposure. Those exposure systems were then used for both in vitro (laboratory) and in vivo (animal) studies. The in vitro studies used human blood and lymph tissue in test tubes and petri dishes that were exposed to EMR. These studies identified the micronuclei in human blood, for example, associated with cell phone near-field radiation. The in vivo studies used head only exposure systems and laboratory rats. These studies identified DNA damage and other genetic markers.

Says Dr. Carlo: “We also conducted four different epidemiological studies on groups of people who used cell phones, and we did clinical intervention studies. For example, studies of people with implanted cardiac pacemakers were instrumental in our making recommendations to prevent interference between cell phones and pacemakers. In all, we conducted more than fifty studies that were peer-reviewed and published in a number of medical and scientific journals.”

Industry Seeks to Discredit Findings, Scientists
But manipulation by the industry had begun almost immediately at the start of research. While Dr. Carlo and his team had never defined their research as being done to prove the safety of cell phones, the industry internally defined it as an insurance policy to prove that phones were safe. From the outset, what was being said by the cell phone industry in public was different from what was being said by the scientists behind closed doors.

The pacemaker studies were a harbinger of bad things to come. Results showed that cell phones do indeed interfere with pacemakers, but moving the phone away from the pacemaker would correct the problem. Amazingly, the industry was extremely upset with the report, complaining that the researchers went off target. When Dr. Carlo and his colleagues published their findings in the New England Journal of Medicine in 1997,11 the industry promptly cut off funding for the overall program. It took nine months for the FDA and the industry to agree on a scaled-down version of the program to continue going forward. Dr. Carlo had volunteered to step down, since he was clearly not seeing eye-to-eye with the industry, but his contract was extended instead, as no one wanted to look bad from a public relations standpoint.

The research continued, and what it uncovered would be a dire warning to cell phone users and the industry’s worst nightmare. When the findings were ready for release in 1998, the scientists were suddenly confronted with another challenge: the industry wanted to take over public dissemination of the information, and it tried everything it could to do so. It was faced with disaster and had a lot to lose.

Fearing the industry would selectively release research results at best, or hold them back at worst, Dr. Carlo and his colleagues took the information public on their own, creating a highly visible war between the scientists and the industry. An ABC News expose on the subject increased the wrath of the industry.

According to Dr. Carlo, “The industry played dirty. It actually hired people to put negative things about me and the other scientists who found problems on the internet, while it tried to distance itself from the program. Auditors were brought in to say we misspent money, but none of that ever held up. They tried every angle possible.”

This included discussions with Dr. Carlo’s ex-wife to try to figure out ways to put pressure on him, he says. Threats to his career came from all directions, and Dr. Carlo learned from Congressional insiders that the word around Washington was that he was “unstable.” But all the character assassination paled in comparison to what happened next.

Toward the end of 1998, Dr. Carlo’s house mysteriously burned down. Public records show that authorities determined the cause of the blaze was arson, but the case was never solved. Dr. Carlo refuses to discuss the incident and will only confirm that it happened. By this time, enough was enough. Dr. Carlo soon went “underground,” shunning the public eye and purposely making himself difficult to find.

Why Cell Phones are Dangerous

A cellular phone is basically a radio that sends signals on waves to a base station. The carrier signal generates two types of radiation fields: a near-field plume and a far-field plume. Living organisms, too, generate electromagnetic fields at the cellular, tissue, organ, and organism level; this is called the biofield. Both the near-field and far-field plumes from cell phones and in the environment can wreak havoc with the human biofield, and when the biofield is compromised in any way, says Dr. Carlo, so is metabolism and physiology.

“The near field plume is the one we’re most concerned with. This plume that’s generated within five or six inches of the center of a cell phone’s antenna is determined by the amount of power necessary to carry the signal to the base station,” he explains. “The more power there is, the farther the plume radiates the dangerous information-carrying radio waves.”

A carrier wave oscillates at 1900 megahertz (MHz) in most phones, which is mostly invisible to our biological tissue and doesn’t do damage. The information-carrying secondary wave necessary to interpret voice or data is the problem, says Dr. Carlo. That wave cycles in a hertz (Hz) range familiar to the body. Your heart, for example, beats at two cycles per second, or two Hz. Our bodies recognize the information-carrying wave as an “invader,” setting in place protective biochemical reactions that alter physiology and cause biological problems that include intracellular free-radical buildup, leakage in the blood-brain barrier, genetic damage, disruption of intercellular communication, and an increase in the risk of tumors. The health dangers of recognizing the signal, therefore, aren’t from direct damage, but rather are due to the biochemical responses in the cell.

Here’s what happens:

Cellular energy is now used for protection rather than metabolism. Cell membranes harden, keeping nutrients out and waste products in.

Waste accumulating inside the cells creates a higher concentration of free radicals, leading to both disruption of DNA repair (micronuclei) and cellular dysfunction.

Unwanted cell death occurs, releasing the micronuclei from the disrupted DNA repair into the fluid between cells (interstitial fluid), where they are free to replicate and proliferate. This, says Dr. Carlo, is the most likely mechanism that contributes to cancer.

Damage occurs to proteins on the cell membrane, resulting in disruption of intercellular communication. When cells can’t communicate with each other, the result is impaired tissue, organ, and organism function. In the blood-brain barrier, for example, cells can’t keep dangerous chemicals from reaching the brain tissue, which results in damage.

With the background levels of information-carrying radio waves dramatically increasing because of the widespread use of cell phones,Wi-Fi, and other wireless communication, the effects from the near and far-fields are very similar. Overall, says Dr. Carlo, almost all of the acute and chronic symptoms seen in electrosensitive patients can be explained in some part by disrupted intercellular communication. These symptoms of electrosensitivity include inability to sleep, general malaise, and headaches. Could this explain the increase in recent years of conditions such as attention-deficit hyperactivity disorder (ADHD), autism, and anxiety disorder?

“One thing all these conditions have in common is a disruption, to varying degrees, of intercellular communication. When we were growing up, TV antennas were on top of our houses and such waves were up in the sky. Cell phones and Wi-Fi have brought those things down to the street, integrated them into the environment, and that’s absolutely new. The recognition mechanism, where protein vibration sensors on the cell membrane pick up a signal and interpret it as an invader, only works because the body recognizes something it’s never seen before.”

As to increases in brain tumors tied to cell phone use, it’s too early to tell due to a lack of hard data, says Dr. Carlo. “We’re never going to see that in time to have it matter. Here in the US, we’re six years behind in getting the brain tumor database completed, and currently the best data are from 1999. By the time you see any data showing an increase, the ticking time bomb is set.”

Epidemic curve projections, however, indicate that in 2006, we can expect to see 40,000 to 50,000 cases of brain and eye cancer. This is based on published peer-reviewed studies that allow calculation of risk and construction of epidemic curves. By 2010, says Dr. Carlo, expect that number to be between 400,000 and 500,000 new cases worldwide.

“This means we’re on the beginning curve of an epidemic, with epidemic defined as a change in the occurrence of a disease that is so dramatic in its increase that it portends serious public health consequences,” says Dr. Carlo. “This is what’s not being told to the public. One of the things that I suggest to people who use a cell phone is to use an air tube headset. If you use a wired headset, the current moving through the wire of the headset attracts ambient informational carrying radio waves and thereby increases your exposure.”

Gauss Meters: Detecting Electromagnetic Radiation

Invisible electromagnetic radiation surrounds us each day, emanating from diverse sources such as power lines, home wiring, computers, televisions, microwave ovens, photocopy machines, and cell phones.

While undetectable to the eye, scientists have proposed that electromagnetic radiation may pose serious health effects, ranging from childhood leukemia to brain tumors.

As scientists continue to unravel the precise health dangers of electromagnetic radiation, it makes good sense to avoid these potentially dangerous frequencies as much as possible. A gauss meter is a useful tool you can use to measure electromagnetic radiation in your home and work environments.

Using the gauss meter at varied locations, you can easily detect electromagnetic radiation “hot spots” where exposure to these ominous frequencies is the greatest. Armed with this crucial information, you can then avoid these areas, re-arranging furniture or electronic devices as needed in order to avoid unnecessary exposure to electromagnetic radiation.

Following the loss of his home, Dr. Carlo collaborated with Washington columnist Martin Schram—who in the course of the work did his own research to corroborate Dr. Carlo’s view on things—to write Cell Phones: Invisible Hazards in the Wireless Age (Carroll & Graf, 2001). He wrote his book as what he thought would be a last volley at the cell phone industry.

“I needed to tell the whole story in one place. I didn’t have the resources or the manpower to match what the cell phone industry was doing to try to discredit the work,” says Dr. Carlo. “Based on the book, a number of lawsuits were brought against the industry, and insurance carriers began excluding cell phone-related health risks in their coverage. It created a very difficult situation in the industry and for myself. I was worn out fighting that battle. In 2002, after I’d done my book tour, I just decided to take a break for a couple of years.”

Instead of taking a break, however, Dr. Carlo ended up working behind the scenes, setting up an organization and a registry for the benefit of consumers. It was a creative solution as part of the settlement of a lawsuit brought by a Illinois citizen against the cell phone industry, WTR, and Dr. Carlo personally. The lawsuit alleged that the cell phone industry, WTR, and Dr. Carlo were conspiring to hide the dangers of cell phones. Dr. Carlo was offered a way out of the suit because his book had made it clear he wasn’t on the same page as the industry.

“I wanted to make sure the litigation brought at least some value to consumers. We created the Safe Wireless Initiative (www.safewireless.org) for disseminating information on the dangers and on prevention, and the Mobile Telephone Health Concerns Registry (www.health-concerns.org) to track information voluntarily provided by cell phone users, particularly those who believe they’re experiencing health effects. Post-market surveillance hadn’t been done before, and the registry does that. It will help direct future research of potential health effects related to cell phone use. In the end, we did the best we could to get some benefit for consumers.”

PROTECTION IS KEY

To repair damage and build the body’s defenses against the onslaught of EMR, supplements—along with dietary changes, stress reduction, weight control and exercise—make you stronger, more balanced, and better able to face the assaults of EMR. Antioxidant supplements that fight free radicals are especially desirable.

Says Dr. Carlo: “You as a human being are put under siege by the electromagnetic soup we’re swimming in, and this isn’t hyperbole, it’s true. When you answer your cell phone, radio signals are around you. Just because you can’t see it doesn’t mean it’s not there. Our general ability to compensate for those insults is becoming compromised by the ever-increasing background of EMR.”

Taking as many precautions as you can goes a long way to reducing the risks. However, Dr. Carlo cautions that there is no silver bullet solution. “It’s a complicated problem, and while we tend to look for a quick fix, there is none here. Over the next decade, I hope we figure out how to change the way signals are transmitted. A thousand years from now we will have evolved, but that’s not helping us now. This will take time, but consumers have to be empowered to help themselves in the interim.”

European Research Confirms Cell Phone Dangers

The industry took its tricks elsewhere—to Europe, which had picked up the ball and began funding independent research to corroborate or confirm the work of Dr. Carlo and his team. The work was completed in mid-2004 and when it was released,12 it not only provided independent scientific corroboration of the work done by Dr. Carlo’s group, but also took the work a step further and showed how the problems were occurring mechanistically. This information formed a biologically plausible hypothesis for how cell phone radiation could be related to so many diseases.

Dr. Carlo noted, “The industry exerted pressure on the scientists who conducted the work, including renowned German scientist Dr. Franz Adlkofer. It first tried to change the conclusions of the work, then to delay its public release. Then Dr. Adlkofer, the lead scientist, was attacked in the media and threatened privately with no more research money, a ruined reputation—similar to what we experienced in the WTR. But this situation attracted the attention of a German documentary filmmaker, who decided to do a film on the cell phone issue.”

It was enough to bring Dr. Carlo into view again, as he was asked to participate. The film, The Boiling Frog Principle, by Klaus Scheidsteger, builds on information from his first film, The Cell Phone War, and will be released in 2007. Its intent is to integrate the latest political and scientific evidence from around the world, and bring forth to consumers important information on cell phone dangers that was previously withheld.

Economic Implications

Currently in the US, there are seven class action lawsuits moving forward against the cell phone industry, says Dr. Carlo, and nine other cases that are personal injury cases brought by people with brain cancer. In the past two years, two workers compensation awards were given to people with brain tumors based on a link between their tumors and their cell phone use in the workplace. Both of these cases occurred in California.

“What we have now is a major litigation burden, a vulnerability the cell phone industry has never before been under,” Dr. Carlo says. “They’re uninsured for these health risk claims and are already positioning themselves for a congressional bailout, like the Savings and Loan crisis of the late 1980s. They’ll lose a couple of these lawsuits and once they do, there’ll be an onslaught of new litigation against them.”

The country can’t afford for the cell phone industry to go under, Dr. Carlo says, as it would have a disastrous impact on the entire economy—some estimates say over 30% of investment stocks in retirement funds are tied to telecommunications shares. That’s why Congress will figure out a way to bail out the industry.

“The industry thinks they can afford to continue on with this institutional arrogance, endangering millions of men, women and children because, at the end of the day, they believe they’ll not be held accountable. They think they can continue to manipulate consumers.”

A Looming Health Crisis

It’s been nearly 12 years since the WTR was funded. Despite Dr. Carlo’s revealing research and the corroborating research of other scientists from around the world that continue to follow, a search of media reports today on the subject of cell phone dangers tends to suggest one of only two conclusions: There is no risk, or no one has yet proven the risk. That’s at odds with more than 300 studies in the peer-reviewed scientific literature supporting an increased risk of disease. Clearly, something doesn’t add up.

The industry’s manipulation of the media to consider only one study at a time obfuscates the big picture.Individually, there’s little to see. But the depth and breadth of the science that points to the problem, and the compilation of studies, make the future look frightening. Like the September 11 tragedy, where no one in government talked to each other and did not see it coming for lack of a big picture view, the health crisis from cell phone use looms darkly.

“When you put all the science together, we come to the irrefutable conclusion that there’s a major health crisis coming, probably already underway,” warns Dr. Carlo. “Not just cancer, but also learning disabilities, attention deficit disorder, autism, Alzheimer’s, Parkinson’s, and psychological and behavioral problems—all mediated by the same mechanism. That’s why we’re so worried. Time is running out. When you put the pieces of the puzzle together, it’s such a wide ranging problem. It’s unlike anything we’ve ever seen before.”

Protecting Yourself

The most effective technique for protecting yourself against the dangers of cell phone radiation is keeping the phone at a distance from the body. Simply using a hands-free headset is a big step. Headsets keep the cell phone’s antenna at a distance of six to seven inches away from the body, thus eliminating near-field exposure. Wired headsets can act as an antenna to draw some ambient EMR, but not much, so using one is still preferable to holding the phone to your head. Wireless headsets should be avoided, as they draw much more far-field EMR.

The safest headsets have hollow air tubes, similar to those used in stethoscopes, instead of wires.They offer protection against both near-field and far-field exposure. If possible, avoid wearing the phone at your waist, which exposes the hip bones to radiation. Eighty percent of red blood cells are formed in the hip bones. There are also newer cell phones available capable of functioning in speaker phone mode. This enables you to talk on the phone while keeping it at a safe distance from your body. If you are able to conduct most of your conversations using a speaker phone, this could enable you to use a cell phone without encountering the intense radiation exposure that occurs when holding it to your ear.

Nutritional Protection against Cell Phone Radiation

As growing evidence points to the potential adverse health impact of exposure to cell phone radiation, scientists are seeking strategies to prevent or mitigate these effects. Currently, nutritional researchers are exploring whether melatonin, vitamin C, and and vitamin E can ameliorate the detrimental effects caused by radiation emitted by cell phones.

To date, a total of eight studies have pointed to the protective effects of melatonin and vitamins C and E in stemming the damage caused by cell phone emissions. In particular, these agents show promise in averting the increased oxidative stress that is thought to contribute to an increased risk of certain cancers. These studies have unveiled statistically significant protective effects of melatonin and vitamins C and E against the effects of the radiation frequency at which cell phones emit and receive radio frequency radiation.

Six of these eight studies were controlled, short-term studies (ranging from 10-30 days) in rodents. Each study examined 24-30 subjects. Study subjects were divided equally into three groups: one group received radiation exposure; another received active treatment with melatonin only, vitamin C only, or vitamins C and E before radiation exposure; and a control group did not receive radiation or active treatment. After the treatment period, scientists examined skin sections for radiation injury and analyzed blood and urine for markers of oxidative stress. They found significant kidney damage, skin changes, oxidative stress, and fibrosis in the animals who received radiation exposure only. Remarkably, these effects were reversed in the groups that received melatonin13-16 and vitamins C17,18 and E.17

Another two controlled studies in rodents, one of 10 days’19 and another of 60 days’ duration,20 revealed that melatonin significantly protects against retinal (eye)20 and kidney tissue19 damage caused by cell phone radiation, as compared with subjects that did not receive melatonin.

Despite this compelling evidence, other avenues of research still need to be pursued after contradictory findings from seven different studies that have looked into the effect of cell phone radiation on melatonin levels in the body.

In one study, melatonin levels in the blood were measured in 226 male electric utility workers who were categorized according to cell phone use. The study concluded that workers who used cell phones for more than 25 minutes per day had decreased melatonin production and revealed a relationship between increased cell phone use and decreasing melatonin levels in the blood.21

Yet six other studies—two in humans22,23 and four in rodents24-27— found that melatonin levels remained unchanged after radiation exposure. One human study did suggest that cell phone radiation may impact melatonin onset time. These were small studies, however, the majority of which were less than 28 days’ duration.

Melatonin is a vital natural neurohormone (hormone secreted by or acting on a part of the nervous system) that acts as a potent free radical scavenger and antioxidant. Melatonin regulates the daily circadian rhythm and is essential to self-repair and regeneration. Given melatonin’s protective effects, these findings warrant further research into the effect of cell phone radiation on melatonin in larger, longer-term, well-controlled human studies.

Waves from microwaves, I-pods may affect health: study
Kolkata, Aug 18:

The next time you use an I-Pod, a microwave oven or a high-speed food processor, make sure you are not exposed to harmful electromagnetic radiation (EMR) that may lead to irritation, violent mood swings or sleeplessness, says a recent study.

The study by Cogent EMR Solutions Ltd, a leader in the field of anti-EMR technology and a member of the Global Wellness Foundation, has found that EMR, a self-propagating wave with electric and magnetic components, poses a major threat to human health due to excessive use of electronic devices.

Carried out with the help of four scientists associated with Defence Research and Development Organisation (DRDO), it found that EMR rates in Delhi, Mumbai and Bangalore were much higher than the permissible limit.

"Electromagnetic radiation is really hazardous for human health as it has penetration power to affect tissues," Zafar Haq, CEO OF Cogent EMR, told IANS, adding that EMR aids in changing energy circulation and behaviour of blood cells in the human body.

It can cause irritation, violent mood swings, sleeplessness, lack of concentration, low sperm count and cancerous diseases, Haq said, adding that they would conduct a similar study in Kolkata next month.

He said mobile phone towers were also a potential source of powerful EMR.

Medical experts, however, underplayed the alarming findings, saying there was no documented evidence to prove that electronic products like mobile phones and microwaves caused health hazards.

"Though EMR has some potential to penetrate human tissues, there is no documented evidence to prove mobile phones, microwave ovens or other household electronic products radiate EMR," said NRS Medical College and Hospital oncology head Subir Ganguly.

Admitting the dangerous effects of EMR, Sukalyan Chattopadhyay of the Saha Institute of Nuclear Physics said electromagnetic waves do damages human tissues.

Chattopadhyay, who is also associated with Big Bang Theory research at CERN in Geneva, added: "Each type of human tissue has certain power to absorb frequency level and if that level exceeds, it does affect human health to a great extent."

He explained that EMR is categorised into several types considering its frequency of waves. These include radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

EMR carries energy and momentum that might be imparted when it interacts with other matter, he said.

The Cogent EMR study for determining the effect of hazardous EMR revealed that exposure of human blood lymphocytes to continuous resonant frequency (RF) radiation of 830 MHz electromagnetic fields for 72 hrs - at temperatures ranging from 34.5 to 37.5 degrees Celsius - could lead to fatal diseases.

Such RF radiation is emitted by high-speed electronic devices, including microwaves, hair driers and automatic shavers.

It found that growing exposure to electric transformers that emit 50-60 hertz low level electromagnetic fields (EMF) may block melatonin, a type of natural neuro-hormone produced by the brain. It can also affect the ability of melatonin to suppress breast cancer cells from further multiplication.

Melatonin helps maintain body temperature and cholesterol levels by reducing risk of coronary heart disease and chances of blood pressure.

It was also observed that eight hours of radiation from a TDMA (times division multiple access) cell phone could result in a 40 percent increase in ornithine decarboxylase (ODC) enzyme level, an indication for increased multiplication of cancer cells.

The study further revealed EMF exposure through mobile phones may affect rapid eye movement during sleep.

High voltage health alarm
MICHELLE PAINE

LIVING near high-voltage power lines, especially in childhood, may increase the risk of leukemia or lymphoma, Tasmanian research reveals.

A study of more than 800 Tasmanian patients tracked how close they lived to high-voltage lines through their lives.

Adults who lived within 300 metres of a line during their first 15 years had triple the risk of lymphoproliferative or myeoloproliferative disorders (LPD or MPD).

These include Hodgkin and non-Hodgkin lymphoma, multiple myeloma and several leukemias.

Those who lived near high-voltage lines from birth to five years had a five-fold increase.


The study by Hobart oncologist Ray Lowenthal, nurse Deirdre Tuck and UK doctor Isabelle Bray is in September's Internal Medicine Journal, published by the Royal Australasian College of Physicians.

"Although recognising that this study has limitations, the results raise the possibility that prolonged residence close to high-voltage power lines, especially early in life, may increase the risk of the development of MPD and LPD later," the authors say.

The study showed a "dose-response effect", so the risk went up the closer people lived to lines, the longer the exposure or higher the voltage.

It adjusted for other risk factors including low socio-economic status and jobs in farming, foundry work, mining and female hairdressing.

They said their results demanded further research, including animal experiments on newborns and in utero.

"It is not the final answer, it is not a perfect study by any means," Dr Lowenthal said.

"We found interesting evidence that needs to be studied by other people and confirmed in other studies, but the results were certainly unexpected."

Transend, which owns and operates Tasmania's electricity transmission system, said it welcomed the report.

"The electricity industry here in Tasmania and around the world monitors this issue and supports scientific research into electric and magnetic fields (EMFs) and their health effects," Transend chief executive officer Richard Bevan said.

He said Transend designed its equipment in accordance with health and safety guidelines, including putting lines in easements, or land corridors, up to 60 metres wide.

"This is a prudent safety measure that ensures lines are at a safe distance from houses, schools, other buildings and structures."

He said the Australian Radiation Protection and Nuclear Safety Agency concluded that on balance the evidence did not indicate that exposure to 50 Hz electric and magnetic fields around the home, office or near transmission lines was a health hazard.

"All electrical equipment gives off EMFs, including domestic appliances and electrical wiring in homes as well as power lines in the street," Mr Bevan said.

The authors noted that studies already showed an association between EMFs and childhood leukemia. This study looked at adult disorders.

They tracked 854 people aged from birth to 94 diagnosed in Tasmania between 1972 and 1980 as well as control subjects picked randomly.

Study shows link between power lines and cancer

A Tasmanian study shows that children living near high-voltage power lines are more likely to develop cancer.

Oncologist Ray Lowenthal led the research, which explores the impact of electric power lines on the development of diseases including lymphoma and leukaemia.

The research shows that people who lived within 300 metres of power lines when they were children were more likely to suffer from cancer.

Tasmania's Cancer Council is calling for further research into the link between power lines and cancer.

The Chief Executive of the Cancer Council, Lawson Ride, says more definitive evidence is needed.

"I think that basically the message is that people shouldn't panic about this, that there's an indication of something going on, we're not quite sure what it is," Mr Ride said.

"We do need a lot more hard evidence to find out if there's any causal relationship between exposure to transmission lines and any sorts of cancer."

"Electric power transmission lines have been s subject of contention and I think this study has shown that we actually need to have a lot more hard evidence," he said.

"We need more study on a national and international basis to find out what the links may be."

Research underlines powerline cancer risk
Bellinda Kontominas Medical Reporter

PEOPLE who live close to high-voltage powerlines during childhood are up to five times more likely to develop cancer, according to Australian research.

The Tasmanian study of more than 850 patients adds weight to the link between electromagnetic fields and cancers such as leukaemia, lymphoma and multiple myeloma. It is still not known whether there is a cause and effect relationship.

Those who lived within 300 metres of a powerline up to the age of five were five times more likely to develop cancer, while those who lived that close to a powerline at any point during their first 15 years were three times more likely to develop cancer as an adult, according to the study published in the Internal Medicine Journal.

Researchers from the University of Tasmania and Bristol University in Britain compared an existing database of all patients in Tasmania diagnosed with lymphatic and bone marrow cancers between 1972 and 1980, with controls matched for sex and age. Residential histories were then gathered.

People who had lived within 50 metres of a high-voltage powerline at any time were at double the risk of developing cancer than those who had never lived within 300 metres of a powerline. For every year lived within 50 metres of a powerline, the risk of cancer increased by 7 per cent, the study found. There was also evidence the risk of cancer increased with higher voltages.

The lead researcher, Professor Ray Lowenthal, from the University of Tasmania, said the debate about possible carcinogenic effects of electromagnetic fields had been going for more than 20 years. "The evidence of detrimental long-term health effects is far from conclusive and international guidelines for limiting exposure to EMF are based on possible short-term effects rather than longer-term disease risks such as cancer," Professor Lowenthal said.

People who lived near powerlines tended to be from lower socioeconomic backgrounds, although the study had attempted to control for this and the occupational risk of cancer.

"Despite the limitations of this study … our novel finding that the risks of adult leukaemia and lymphoma are most strongly associated with early childhood exposure to powerlines deserves further study at both the population and laboratory levels."

Bruce Armstrong, Professor of Public Health at Sydney University said the study was consistent with previous research.

"I think we are in a position where we have to say that there is a possibility that exposure to electromagnetic fields increases the risk of some cancers, but I don't think we know yet whether powerlines actually cause cancer."

EMFs and Childhood Leukemia

Referencing: Risk Factors for Acute Leukemia in Children: A Review

In their otherwise informative and concise review of the current state of evidence concerning risk factors for acute childhood leukemia, Belson et al. (2007) did not correctly address nonionizing radiation and, in particular, power frequency magnetic fields as a possible risk factor for childhood leukemia. This failure may be due to a widespread misconception about the evidence concerning nonionizing electromagnetic fields (EMFs) as a health hazard. It is also apparent in the Churchill County leukemia cluster study published in the same issue, in which Rubin et al. (2007) investigated a multitude of factors, many with sparse or ambiguous previous evidence of an association with childhood leukemia. Although power frequency magnetic fields have been classified as a possible human carcinogen (group 2B) by the International Agency for Research on Cancer (IARC 2002) and by a National Institute of Environmental Health Sciences (NIEHS) working group (NIEHS 1998), based on the evidence of an association with childhood leukemia, these were apparently not considered by Rubin et al. (2007).

In their review of nonionizing radiation, Belson et al. (2007) inappropriately mixed original research and pooled analyses, further contributing to the prevailing confusion. Both Ahlbom et al. (2000) and Greenland et al. (2000) presented pooled analyses that included the important study of Linet et al. (1997). Hence, it is inappropriate to present results of the latter as an independent source. Almost all epidemiologic studies of residential exposure to power frequency magnetic fields published before 1999 are included in either the pooled analyses of Ahlbom et al. (2000) or Greenland et al. (2000). Only the study of Myers et al. (1990) was not included because authors refused to provide requested data. Although the study of Linet et al. (1997) is often cited as failing to support the hypothesis of an association between residential exposure to magnetic fields and childhood leukemia [it was also cited by Belson et al. (2007)], it actually was one of the most important supporters of an association in the pooled analyses and contributed the greatest number of highly exposed children. Two large and well-conducted studies published after the pooled analyses (Kabuto et al. 2006; Schüz et al. 2001) lend further support to the results of the pooled analyses of an increased risk from high average levels of magnetic field exposure.

It is also incorrect to characterize the evidence as "some have found a small association . . . while others have not . . . ." First of all, the association is not small, but is comparable or larger than that for all other factors considered by Belson et al. (2007). Second, the evidence is consistent across different continents, study types, measurement methods, and other factors. Of course, there are potential sources of bias, in particular selection bias. However, thorough investigations of these potential biases have rendered it unlikely that they can completely explain the association. Up to now, there is no other risk factor of childhood leukemia that has been as comprehensively studied concerning possible biases and confounding factors.

It is high time that exposure to power frequency EMFs is recognized as a potential risk factor for childhood leukemia and is properly included in the protocols of cluster studies and in epidemiologic studies of other risk factors as a potential confounder.

The author declares he has no competing financial interests.
