Hazards of Microwave Radiations - A Review
Authors not listed · 1960
Scientists were documenting microwave radiation health hazards in 1960, decades before WiFi and smartphones became ubiquitous.
Plain English Summary
This 1960 review examined the health hazards of microwave radiation exposure, focusing on occupational risks from radar systems and medical diathermy equipment. The study analyzed both thermal effects (tissue heating) and potential non-thermal biological impacts of microwave frequencies. This early research helped establish the foundation for understanding microwave radiation's effects on human health.
Why This Matters
This 1960 review represents a pivotal moment in EMF health research, appearing just as radar technology was proliferating after World War II and medical diathermy was becoming common. The science demonstrates that concerns about microwave radiation aren't new or fringe - they were being documented by mainstream researchers over six decades ago. What this means for you is that today's microwave exposures from WiFi routers, cell phones, and smart meters operate at similar frequencies to those flagged for health concerns in 1960, yet our daily exposure levels have increased exponentially. The reality is that while this early research focused primarily on occupational exposures to high-power radar and medical equipment, we now carry microwave-emitting devices in our pockets and homes. The biological mechanisms identified in this foundational work - both thermal heating and non-thermal cellular effects - remain relevant to understanding how today's chronic, low-level microwave exposures might affect our health.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
All tissues of the body are not equally equipped for heat dissipation and temperature regulation. The lens of the eye and hollow viscera, such as gallbladder, urinary bladder, and parts of the gastrointestinal tract, for example, are comparatively avascular and largely devoid of effective temperature regulating mechanisms. It is reasonable to expect that such organs will suffer relatively larger temperature rises and will be more liable to injury by microwave irradiation than other body organs. Experiments have, in fact, shown that severe and injurious temperature increases occur in these organs under microwave irradiations accompanied by only slight increases in rectal and oral temperature. It is not clear whether all biologic effects of microwaves can be attributed solely to temperature increases that result from energy absorption, or whether these effects are produced in part by mechanisms other than simple thermal elevation. Hines and Randall were unable to find any crucial experimental evidence for biologic effects unrelated to temperature change. It should be pointed out, however, that at this time it is impossible to rule out completely the possibility of athermal effects of microwaves.
