Abstract

Two overriding considerations shaped the development of early research on the biological effects of microwave radiation—possible medical application (diathermy) and uncertainty about the hazards of exposure to radar. Reports in the late 1940s and early 1950s of hazards resulting from microwave exposure led to the near abandonment of medical research related to microwave diathermy at the same time that military and industrial concern over hazards grew, culminating in the massive research effort known as ‘the Tri-Service program’ (1957–1960). Both the early focus on medical application and the later search for hazards played important roles in dictating how this field of research developed as a science.

Main findings

This historical review describes how early research on microwave biological effects from 1940 to 1960 was shaped by interest in medical diathermy and by uncertainty about radar-related exposure hazards. It reports that hazard reports in the late 1940s and early 1950s shifted attention away from medical applications toward military and industrial hazard research, including the Tri-Service program.
