The authors concluded that prolonged workplace microwave exposure may contribute to developing stomach ulcers.
Milton M. Zaret, M.D. · 1973
This 1973 case report documented cataract development in a person following microwave oven use, representing early clinical evidence linking microwave radiation exposure to eye damage. The study examined the connection between microwave exposure and lens opacity formation in the human eye. This was among the first medical reports to document potential eye injury from consumer microwave appliances.
Robert M. Lebovitz · 1973
This 1973 study proposed that microwave radiation affects the inner ear's balance system by creating thermal gradients in the semicircular canals, causing vestibular stimulation and eye movement responses (nystagmus). The research estimated humans could detect these effects at 35 mW/cm² power density, suggesting microwave exposure can trigger balance responses without causing obvious heating effects.
Arthur W. Guy et al. · 1973
This 1972 study used mathematical models to calculate how high-frequency radio waves are absorbed by the human body and converted to heat. Researchers found that at 20 MHz and below, power absorption is extremely low - requiring exposure levels hundreds of times higher than microwave safety standards to cause significant body temperature increases.
Raymond L. H. Murphy et al. · 1973
Researchers tested whether doctors could accurately diagnose heart murmurs using microwave-transmitted stethoscope sounds from 2.7 miles away. The study found that all significant murmurs (grade 2/6 or higher) were correctly identified through the microwave telestethoscope system, though 2 of 32 very mild murmurs were missed. This 1973 research demonstrated that microwave transmission could enable remote cardiac diagnosis.
Colonel Budd Appleton · 1973
This 1973 report by Colonel Budd Appleton described clinical surveys of military personnel working with radar equipment, conducted to determine whether microwave exposure causes ocular effects. About 1,000 individuals were examined at multiple military locations, and exposed and control groups were compared on opacities, vacuoles, and posterior subcapsular iridescence. The preliminary results showed no statistically significant differences in ocular findings between exposed and control populations.
Arthur W. Guy et al. · 1973
This 1973 study used mathematical models to calculate how much radiofrequency energy a 70-kilogram human would absorb at 20 MHz and below frequencies. Researchers found that exposure to 590 mW/cm² at 20 MHz would raise core body temperature by 2.1°C after 100-120 minutes, requiring the body to work harder to maintain thermal balance.
Richard Felger, Mary Beck Moser · 1973
This 1973 study by Frey demonstrated that humans can actually "hear" pulsed microwave radiation without any sound waves reaching their ears. Researchers found that people perceived these phantom sounds based on the peak power of the electromagnetic pulses, not the average power level. The pitch and tone quality of these perceived sounds changed depending on how the microwaves were modulated.
Nicholas P. D. Smyth et al. · 1973
Researchers tested 52 pacemaker patients against magnetic fields from airport weapons detectors (100 Hz to 450 kHz, 0.5-1.35 gauss) to assess hijacking prevention safety. Standard pacemakers showed no interference, while newer atrial and synchronous models had minimal, clinically insignificant effects. The study confirmed airport magnetic detectors pose no health risks to pacemaker patients.
Guy AW, Taylor EM, Ashleman B, Lin JC · 1973
This 1973 technical report examined how microwave radiation interacts with the hearing systems of both humans and cats. The research represents early scientific investigation into whether microwave energy can affect auditory function, a phenomenon that would later become known as the microwave auditory effect.
E.A. Kolesnik, N.A. Komogortseva · 1973
Soviet researchers in 1973 studied workers exposed to superhigh-frequency (SF) radiation generators and found they had significantly decreased levels of sulfhydryl groups in their blood compared to unexposed controls. Sulfhydryl groups are crucial for enzyme function, nerve impulses, and cellular energy processes, making their reduction a potential marker of biological harm from RF exposure.
William H. Walter et al. · 1973
Researchers in 1973 tested various cardiac pacemakers against electromagnetic radiation found in urban environments. Many devices malfunctioned when exposed to EMF levels similar to those measured in a major metropolitan area, either switching to fixed-rate mode or shutting down completely. This early study revealed that life-saving medical devices were vulnerable to everyday electromagnetic interference.
B. Stefanov, I. Zlatarov, A. Solakov · 1973
This 1973 Bulgarian study examined how radiofrequency electromagnetic waves affected various body systems in workers exposed to RF radiation at different job sites. Researchers found that RF exposure impacted multiple organ systems including the nervous system, cardiovascular system, blood formation, and temperature regulation. The study represents early recognition that occupational RF exposure poses health risks across multiple biological systems.
Zoran Đorđević · 1973

Researchers measured radiation intensity in radar units and analyzed changes in blood parameters among workers exposed to these microwaves. The research represents early occupational health investigation into microwave exposure effects on human blood.
George F. D'Cunha et al. · 1973
A patient with a Medtronic 5842 pacemaker experienced repeated fainting episodes when near a television transmitter due to radio frequency interference disrupting the device's function. Switching to a titanium-shielded Medtronic 5942 pacemaker resolved the problem, demonstrating that RF fields from broadcast transmitters can interfere with certain medical devices.
James C. Lin, Arthur W. Guy, Curtis C. Johnson · 1973
This 1973 theoretical study used spherical models to calculate how much radiofrequency energy the human body absorbs when exposed to electromagnetic fields between 1-20 MHz. The researchers found that at these frequencies, power absorption is extremely low - less than 2.5×10⁻³ milliwatts per gram of body tissue per milliwatt of incident radiation. The study suggested that thermal safety levels for HF frequencies could be much higher than the 10 mW/cm² recommended for microwaves.
