ABSTRACT
Until the late 1940’ s, the primary interest in the biological effects of radiofrequency (RF) radiation was in heating for medical applications (1). Thus, the dominant theme of the research was the use of high powers to heat tissue. With the development and increasing use of RF radiation as radar in the 1940’s, however, questions were increasingly raised about the possibility that exposure to this energy would have adverse biological effects on military personnel and workers.
