The implications are unsettling, to say the least, since everyone comes into contact with such fields ,which are generated by everything electrical, from power lines and antennas to personal computers and micro-wave ovens. Because evidence on the subject is inconclusive and often contradictory, it has been hard to decide whether concern about the health effects of electricity is legitimate or the worst kind of paranoia.
