Trends in Nonionizing Electromagnetic Radiation Bioeffects Research and Related Occupational Health Aspects

AbstractThe international literature (circa 1970-1977) on biological and clinical phenomena associated with exposure to microwave or radio frequency (RF) electromagnetic (EM) fields was selectively reviewed. It was concluded that the mechanisms by which EM fields exert their biological effects are becoming better understood as investigative technology and methodology improve. Concurrent with this trend, there is some recent evidence in the West which supports traditional Soviet and some European claims that EM fields can affect nervous system function and morphology in small mammals, birds and invertebrates at power levels below those defined as thermogenic in the West. These experimental findings coupled with the pressure of public opinion may eventually have a significant effect on the establishment of revised occupational exposure limits and on unique positions regarding maximum permissible exposures (MPE). At present, the exposure level established in the Soviet Union is 0.01 m W/cm2 for a work day, w...
