Medical considerations of exposure to microwaves (Radar)
Barron CI · 1959
Medical professionals recognized radar microwave exposure as a health concern requiring surveillance protocols as early as 1959.
Plain English Summary
This 1959 medical review examined the health considerations for workers exposed to radar microwaves, focusing on occupational safety protocols and medical surveillance needs. The study addressed early concerns about microwave exposure from radar systems that were becoming widespread in military and civilian applications. This represents one of the earliest formal medical assessments of microwave radiation exposure in occupational settings.
Why This Matters
This 1959 study stands as a remarkable piece of EMF history, documenting the medical profession's early recognition that microwave radiation warranted serious health consideration. What's striking is that concerns about radar exposure emerged just as these technologies were proliferating across military and civilian sectors. The fact that medical surveillance protocols were being developed over 60 years ago underscores how long we've known that microwave radiation poses potential health risks.
Today's radar systems operate at similar frequencies but with different power levels and exposure patterns. While occupational radar exposure typically involves much higher power densities than consumer devices, the biological mechanisms of microwave interaction with human tissue remain fundamentally the same. This early medical attention to radar workers' health provides important historical context for understanding why today's concerns about cell phones, WiFi, and other microwave-emitting devices aren't unfounded paranoia but rather the continuation of legitimate scientific inquiry that began decades ago.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: Exposures varied from an occasional incidental contact with the beam to as much as 4 hours daily close exposure periods up to 4 years
Study Details
To detect any cumulative biologic effects of long-time exposure to microwaves of varying frequency and power output in persons who had taken minimal precautions; to observe possible effects on persons working for short periods with or near extremely high-powered airborne radar with pulsed wave emissions; and to establish correlation between objective findings and units of exposure expressed in time-powered density factors with the highly idealized objective of establishing safe maximum exposure standards.
The study included 226 radar-exposed employees and 88 non-exposed control subjects. Examination incl...

The study revealed no acute, transient, or cumulative physiologic or pathologic changes in subjects working with, and frequently exposed to, high-power radar transmitters. Therefore, it would appear extremely unlikely that there exists a biologic hazard to the radar technician observing reasonable precautions or that the general public, exposed to greatly attenuated and intermittent doses of microwaves in the environment, is in any danger of injury.
