...some qualified support from the Environmental Protection Agency. In the executive summary of a new scientific review, released in draft form late last week, the EPA has put forward what amounts to the most serious government warning to date. The agency tentatively concludes that scientific evidence "suggests a causal link" between extremely low- frequency electromagnetic fields -- those having very long wavelengths -- and leukemia, lymphoma and brain cancer. While the report falls short of classifying ELF fields as probable carcinogens, it does identify the common 60-hertz magnetic field as "a possible, but not proven, cause of cancer in humans...
Doubts about weak, so-called nonionizing radiation began to grow in 1979, when a study of cancer rates among Colorado schoolchildren found that those who lived near power lines had two to three times as great a chance of developing cancer. The link seemed so unlikely that when power companies paid to have the original study replicated, most scientists expected the results to be negative. In fact, the subsequent study supported the original findings, which have since been buttressed by reports showing increased cancer rates among electrical workers...
While many experts still express skepticism, there has been a definite shift of attitude in the scientific community about the possible health effects of electromagnetic fields, as a recent series in Science magazine made clear. "In the 1970's ((the link)) seemed absurd," the articles concluded. "Now it's a legitimate open question...
...Pentagon is far from persuaded. In a blistering 33-page critique of the EPA report, Air Force scientists charge its authors with having "biased the entire document" toward proving a link. "Our reviewers are convinced that there is no suggestion that ((electromagnetic fields)) present in the environment induce or promote cancer," the Air Force concludes. "It is astonishing that the EPA would lend its imprimatur on this report." The Pentagon's concern is understandable. There is hardly a unit of the modern military that does not depend on the heavy use of some kind of electronic ! equipment, from huge ground...
