Abstract
Biological effect of microwaves and electromagnetic radiation of lower frequency is reviewed, with particular reference to the problem of the so-called extrathermal effect, which - in the author's opinion - should be given due consideration. The assumption that the biological effect of microwaves is only based on thermal effect, unduly simplifies the whole problem, especially in connection with the determination of maximum permissible doses. The results are presented of the clinical observations of a larger group of persons occupationally exposed to microwaves ranging from 750 to 200 MHz. These results indicate that in the group with prolonged exposition the occurrence of some symptoms was considerably higher than in the control group. The results of some experimental work on the effect of microwaves, with special reference to the so-called thermal effect, are also discussed.
