Electromagnetic Fields: Are They Dangerous?

Are electromagnetic fields given off by electricity dangerous? For the past decade, a debate over that question has raged among scientists and activists. Now a scientific consensus is developing—not that EMFs are dangerous, but that they may be and that they must be investigated further. Over the next few years, therefore, scientists will try to decide the issue conclusively. In the meantime, experts advise only “prudent avoidance” of EMFs. Although they say further action is not warranted, in many places fierce political and legal battles are being waged by a frightened public.
