Microwave radiation: an epidemiologic assessment

Microwave radiation is coming into increasing use in many countries; it is in use in communications, in industry, for ovens in the home and in commercial establishments and for diathermy. The power output is increasing steadily and community exposure is already a fact. East European countries claim that adverse effects can result from exposure substantially lower than levels permitted in Western countries. Also some of the effects claimed are frequent and disabling. Prolonged and cumulative exposure is especially suspect. While studies in animals are necessary, studies in man cannot be dispensed with. Extrapolation from on species of animal to another, and even more, to man, is hazardous. Moreover, epidemiologic studies are needed to uncover the potentially wide variety of subtle effects, especially mental. Fortunately, there are indices of exposure which can be used in field studies and dosimetry is reaching the point where it can be applied to field studies.
