The effects of microwaves - A preliminary investigation
Boyle AC, Cook HF, Buchanan TJ · 1950
This 1950 study represents the earliest scientific investigation into microwave biological effects, establishing foundational research that still guides modern EMF safety standards.
Plain English Summary
This 1950 study by A.C. Boyle represents one of the earliest scientific investigations into microwave radiation's biological effects on humans. The research examined heating effects and potential tissue damage from microwave exposure, marking a foundational moment in EMF health research. This pioneering work helped establish the scientific framework for understanding how microwave energy interacts with human biology.
Why This Matters
This study holds remarkable historical significance as one of the first formal investigations into microwave biological effects, predating widespread consumer microwave technology by decades. Published in 1950, Boyle's research emerged during the early development of radar and microwave communications, when scientists first began questioning whether these powerful new electromagnetic technologies might affect human health. The focus on heating effects and tissue damage reflects the initial understanding that microwaves primarily work through thermal mechanisms - the same principle later used in microwave ovens.
What makes this research particularly relevant today is how it established the scientific foundation for microwave safety research that continues to guide exposure standards. The reality is that modern microwave exposures from WiFi routers, cell towers, and wireless devices operate at similar frequencies to those studied in 1950, yet at much lower power levels. This early work reminds us that concerns about microwave radiation effects aren't new - they've been part of the scientific conversation for over 70 years.

Study Details
To investigate the biological and thermal effects of micro-waves on human and animal tissues using contact applicators with 10-centimetre wave-length radiation, focusing on dosage measurement and temperature distribution.
Experiments conducted using a 10-centimetre radar set with cavity magnetron delivering short pulses ...
Skin temperature rises were recorded with 3-watt power levels producing comfortable warmth sensation...
Micro-waves produce heat in tissues mainly through dipolar action of water molecules. The heating effect is confined to first few centimeters below skin surface, more penetrating than radiant heat but less than short-wave diathermy. Accurate dosage measurement is practicable with localized fields. Micro-waves may be valuable for treating ophthalmic conditions, sinusitis, localized septic lesions, and superficial rheumatic disorders. Future work should investigate continuous-wave radiation and 3-centimetre wave-length effects.
