Everyone is exposed every day to diverse electromagnetic fields of different frequencies that permeate our environment. This exposure to a wide range of frequencies is growing largely as a result of the accelerated technological development and the advent innovative equipment and appliances.
While the enormous benefit of using electricity in everyday life and health care are unquestioned, in the past 20 years the general public has become increasingly concerned about potential adverse health effects of exposure to electric and magnetic fields especially in the extremely low frequency (ELF) range, whose upper limit is specified as 3000 Hz. The sources involved are mainly transmission and use of electric energy namely 50/60 Hz level.
There is no unequivocal answer regarding the biological effects and health hazards of exposure to power-frequency fields. Under these circumstances, the safety regulations assume high safety factors so enacted as to cover for the uncertainty. Two approaches crystallized: according to one, resources should be invested with a view to better insight into the subject; according to the other - in the absence of certainty as to a hazard, resources should be channeled elsewhere.
The goal of this work is to critically review and evaluate the experimental information accumulated to date as to the biological effects and health hazards of the exposure to electromagnetic fields, conduct some statistical calculations as to the statistical significance of reported effects, and to formulate an attitude regarding the adequacy of the current safety regulations on the basis of the available data.
