Are you one of the addicted doubters? Well then – hold the phone and review this page.

Dr. Devra Davis, PhD., MPH, is an award-winning, internationally renowned scientist who also was the founding director of the Board on Environmental Studies and Toxicology of the U.S. National Research Council, National Academy of Sciences.  Dr. Davis is currently Founder and President of Environmental Health Trust.   On April 4, 2012, she gave a presentation on the hazards of exposure to RF  emissions from cellphones at a meeting of the National Institute of Environmental Health Sciences.

Devra’s introduction:

“So, I want to tell you how I came to be concerned about this issue.  And I want to explain, as I said informally a few moments ago, like most of you in this room, when I first heard there could be a problem with cell phones, I just did not believe it.  At the time, I had three phones, and I was kind of proud of my ability to keep up with all my grad students.  Well, I began to look, and I learned that I was mistaken in my assumption that if there were a problem I would know about it, because after all I’d worked at some of the most important scientific institutions in the world.”

“Now, just to set the context, the electromagnetic spectrum goes all the way from the things that drive our radios to the ones that are in outer space that are clearly very damaging: x-rays, gamma rays, UV.  The microwave spectrum … includes cell phones, microwave ovens, cordless phones and Wi-Fi.  …  They all use a similar frequency, namely the frequency of about 800 megahertz to 2400 megahertz, or .8 gigahertz to 2.4 gigahertz.  The power of a microwave oven is 1000 watts.  That can boil a cup of water in a minute.  (or boil the frog slowly)

The power of a cell phone is much less than 1 watt, and it was thought for a long time that therefore it had no biological impact. That is not the case.  The biological impact of cell phone radiation is not related to its power.  It’s not related to its power.  It is, in fact, quite weak. It is related to its erratic nature of the signal and its ability to disrupt resonance and interfere with DNA repair.  

And I’m going to show you some of the reasons why scientists believe that that is the most plausible theory for understanding the wide array of health impacts that pulsed digital signals from cell phones can have today.”

“So we are, in fact, conducting an experiment right now on all of you. …  We are, in fact, conducting an experiment right now with 5.5 billion cell phones. …  I thought there was nothing to it, really.  And I really thought I would know if there was anything important.  And I realize that although I didn’t recognize it at the time, I could be just as arrogant as other people, and I was wrong.  I was quite wrong, and now I’m going to show you why.  But think about this:  if we go through with cell phones, what we have just gone through with tobacco, and asbestos, and vinyl chloride, and bisphenol A, and obesogens, and other things that we’re now identifying, what this will mean for our planet.   It’s something of grave concern.”

“… the reality is we have information here that suggests that we have a big problem.  And we need to figure out how to study it better, and how to develop responsible public policies, while we continue to do that.”


Transcript for Dr. Davis’s Presentation, April 2012



The career of Dr. Devra Davis has spanned all areas of academia, public policy, and scientific research.  President Clinton appointed the Honorable Dr. Davis to the newly established Chemical Safety and Hazard Investigation Board, (1994-99) an independent executive branch agency that investigates, prevents, and mitigates chemical accidents.  As the former Senior Advisor to the Assistant Secretary for Health in the Department of Health and Human Services, she has counseled leading officials in the United States, United Nations, European Environment Agency, Pan American Health Organization, World Health Organization, and World Bank and served as a member of the Board of Scientific Counselors of the U.S. National Toxicology Program, 1983-86.

Dr. Davis holds a B.S. in physiological psychology and an M.A. in sociology from the University of Pittsburgh, 1967.  She completed a Ph.D. in science studies at the University of Chicago as a Danforth Foundation Graduate Fellow, 1972 and a M.P.H. in epidemiology at the Johns Hopkins University as a Senior National Cancer Institute Post-Doctoral Fellow, 1982.  She has also authored more than 190 publications in books and journals ranging from the Lancet and Journal of the American Medical Association to Scientific American and the New York Times and elsewhere.

Honored for her research and public policy work by various national and international groups, she has been a Fellow of both the American Colleges of Toxicology and of Epidemiology.  She was honored by the Betty Ford Comprehensive Cancer Center and the American Cancer Society with the Breast Cancer Awareness Award, commended by the Director of the National Cancer Institute for Outstanding Service, and appointed a Global Environmental advisor to Newsweek Magazine.

      Thank you for your excellent insight and information. Please feel free to update us as often as you like.
      My best to you!


  1. I must say I was quite impressed when I first discovered the work of Devra Davis. Yet after watching interviews and reading transcripts on the Joseph Mercola site back in 2011, my enhancement declined precipitously from interview to interview. A brief review of her credentials and contacts with very important agencies of health and government, would lead one to believe she must’ve been wearing blinders over eyes and ears the whole time.
    Electromagnetic damage to biological cells has been a know quantity for well over 50 years in both military and civilian scientific circles. The Department of the Navy was already investigating EM radiation damage in personnel as far back as 1946. Those studying to get FCC licensing for radio/television broadcast as far back as 1966, were at least educated in a cursory way toward potential health hazards involved in close EM proximities to broadcast transmitters and antenna systems. And these were strictly analog signals. Digital broadcast didn’t exist in civilian networks until much later, even though there was strong existing documentation that would advised against ANY licencing of digital broadcast devices whatsoever. Thank Tom Wheeler, Motorola, and Bell Labs for this.
    I had two associates in the early 70’s who had both received FCC licensing approvals. Both of these parties were aware of potential EM effects on human health. A EM radiation paper was made privy to the public in Scientific American sometime in about 1978. Many folks playing with citizens band radio transmitters in the 70’s were also apprised of these potential effects. Where was Devra Davis or associates in her field of epidemiology during these years? My purpose here is not to denigrate Devra Davis as an particular case, but let’s ask ourselves how all the information offered in the link below could have escaped the notice of those we entrust to inform and protect American citizens from destroying themselves.

    This is an excellent article regarding the ongoing crisis of electromagnetic pollution, and the fact that most of this information was well documented by the United States Navy and other parties over 50 years ago.

    Excerpt: [In July 2010, a previously unrecognized collection of nearly 5000 studies linking low-level wireless signals to bioeffects was discovered by noted scientist, Magda Havas, PhD of Trent University in Ontario, Canada. More than 2300 of these studies, concerned with radio-frequency and microwave radiation, were compiled by Dr. Zorach Glaser, PhD, an officer in the US Navy at the request of the Naval Medical Research Institute. Many of these studies were previously classified and others originated in Eastern Block nations such as the USSR, Poland and Czechoslovakia and have only recently been translated. Here is a sampling from Dr. Glaser’s report on the 122 biological phenomena (effects) and clinical manifestations attributed to microwave and radio-frequency radiation:]
