RISK ANALYSIS OF HUMAN EXPOSURE TO ELECTROMAGNETIC FIELDS

Do you feel zapped, disconnected, electronically polluted by electromagnetic fields in your homes and workplace? Are you fearful of your electricity? These three books will feed your fears.
But are such fears justified? Public debates have been going on for more than a century about the possible health hazards of electromagnetic fields from power lines and radio-frequency energy from broadcast transmitters—and now cellphones. At the same time, health agencies have repeatedly reviewed the scientific literature and found no clear evidence of a problem. How can these totally different perspectives be reconciled?
Disconnect is the latest tome by Devra Davis, an epidemiologist with a variety of academic appointments on her résumé. Her previous books have excoriated other industries for the risks of their products, and in 2007 she founded an organization, Environmental Health Trust, «capitalizing on growing public interest» in them. InDisconnect she turns her attention to one of the «addictive delights of our technological age»—cellphones.
Davis writes in a popular style, personalizing her story with interviews with ordinary citizens who used cellphones and later developed brain cancer or other diseases. Her heroes are scientists who, she says, made breakthrough discoveries about the hazards of radio-frequency energy, only to be stymied by a cellphone industry that tried to stop their funding or disarm them by funding other scientists to cloud the issue with unsuccessful replication studies. Picking through the large scientific literature on biological effects of radio-frequency energy, Davis presents the case that «cell phones are not safe» and worries that half of the roughly 4 billion cellphone users throughout the world are under the age of 20.
In her less rigorous book, Zapped, Ann Louise Gittleman takes aim at electromagnetic fields of all sorts, from those emitted by cellphones to the much lower frequency fields associated with power lines. «You may be surprised—even shocked,» she says, «to discover that on a daily basis you are exposed to some form of electromagnetic radiation that may be compromising your health.» She describes the «electrosensitivity syndrome» that causes people to experience «a variety of often debilitating symptoms when they’re exposed to even low-level radiation.»
Gittleman, who has a Ph.D. in holistic nutrition from the Clayton College of Natural Health and calls herself «the First Lady of Nutrition,» says readers can «zap-proof» their lives by making «food and [food] supplements your radiation shield.» Her «Zapped Diet» contains «the nutrients your body needs to help neutralize the stressful impact from EMF [electromagnetic field] side effects,» and recommends honeybee food supplements (for its caffeic acid, a component of bee resin) and eating lots of walnuts. She provides links to activist organizations concerned about health effects of electromagnetic fields, and to homeopathic practitioners offering «internal EMF protection detoxification.»
Samuel Milham, in his short professional autobiography Dirty Electricity, describes his longstanding interest in the possible health risks of environmental electromagnetic fields, which he clearly views as real. Milham is best known for his studies beginning in the 1980s linking electricity-related occupations and cancer risks (for example, being a ham radio operator and leukemia; using an electric typewriter and breast cancer). These studies provoked much discussion but had little influence on health agencies (lack of exposure assessment was a major problem). Over time, he became focused on «dirty electricity,» which is his term for electrical noise on power circuits, typically from light dimmers or other appliances. This also had little influence on health agencies, including his own (the Washington State Department of Health, where he worked as an epidemiologist for over 20 years), but it has inspired numerous Web sites on the issue.
In 1992 and facing demotion, Milham retired at age 60 to begin a second career as an expert witness for citizens’ groups protesting power lines. Even now, nearly 20 years later, he carries a special meter with him to measure noise on power circuits, which can sometimes be reduced by removing fluorescent lights. But «few electricians understand or know how to deal with dirty electricity,» he writes, and his letters to schools and hospitals warning of its dangers have frequently been met with silence—or sometimes with cease-and-desist letters by attorneys. «We cry Enough. Enough, Dr. Milham, Enough,» one school board attorney ended his letter, the author reports.
In their very different ways, all three books tell the reader that electromagnetic fields, from power-frequency fields to microwaves, pose great health risks at exposure levels that an ordinary citizen would experience in daily life. But is it true?
Considered as scientific arguments, all three books leave a lot to be desired.
Disconnect, which has the most sustained argument for health risks of radio-frequency energy, is egregiously slanted. Davis picks and chooses her data, favorably describing a primitive 1975 study that claimed to show that radio-frequency energy disrupts the physiological barrier between blood and the brain, but not the better-conducted studies mounted in response to this report, mostly funded by government, that failed to confirm the original finding or the decades of controversy on this issue that followed without clearly identifying a real effect apart from obvious effects of thermal damage at high exposure levels (for a recent review, seehttp://dx.doi.org/10.1016/j.crhy.2010.09.001). She quotes disparaging comments by the researcher who conducted the 1975 study about a retired professor who is an eminent researcher in the field, but she does not interview the professor himself or present his views fairly. Disconnect lacks detailed endnotes, making it difficult for readers unfamiliar with this field to check her sources for themselves.
And there is a basic plausibility problem with Davis’s claim that an industry cover-up exists about health risks of radio-frequency fields. In Europe, in particular, national health agencies have mounted large interdisciplinary research programs in search of possible hazards of cellphones, managed at arms length from industry, including one I reported on, a 17 million (US $23 million) program in Germany that found no adverse health effects from cellphone radiation. Too many scientists have been involved with this issue for any industry cover-up to succeed even if one were attempted.
Gittleman, apart from her nutty (and delectable) nutritional advice, commits a number of scientific bloopers, saying at one point that ultrasound scanning devices «expose the fetus to 3.5 to 5.0 MHz electrical fields» and, elsewhere, that ionizing radiation «causes harm through heat.» Gittleman profiles «electrosensitive» individuals, but she fails to discuss the numerous blinded trials that showed that these individuals are unable to determine when they’re actually being exposed to electromagnetic fields and react only when they think they’re being exposed (this literature was thoroughlyreviewed in 2005).
Her view, that exposure to any kind of electromagnetic field at any exposure level is harmful and that this harm can be prevented by using nutritional supplements—is scientifically poorly defined and medically untested. And Milham’s professional anecdotes are hardly a sustained scientific argument.
