This 1972 Soviet review examined how chemical substances interact with ultrahigh frequency electromagnetic radiation exposure. The study explored the combined effects of microwave radiation and various chemical preparations, representing early research into how EMF exposure might interact with pharmaceuticals and other chemical compounds in biological systems.
Herman P. Schwan · 1972
This 1972 foundational study by biophysicist H.P. Schwan examined how microwave radiation interacts with human tissues and established early safety standards. Schwan classified biological effects as either 'strong' (requiring high field strengths) or 'weak,' and argued that pulsed microwave fields cannot cause more biological damage than continuous fields of the same average power.
Arthur W. Guy, James C. Lin, Fredric A. Harris · 1972
This 1972 study exposed cats' heads to 915 MHz microwave radiation and measured changes in their nervous system responses to touch and sound. The researchers found that brain activity was altered at power levels around 5 mW/cm³, with temperature increases occurring alongside these neurological changes. This early research demonstrated that microwave radiation can directly affect central nervous system function in mammals.
R. B. GRAHAM, JOHN M. HEMPHILL · 1972
This 1972 technical report evaluated the NARDA Model 8300 power density meter, an early instrument designed to measure electromagnetic energy levels from radio frequency sources. The study examined the meter's performance characteristics, including its thermocouple-based detection system for quantifying RF power density in various environments.
Dino O. Fieni · 1972
This 1972 Department of Defense technical report examined radiation hazards in metropolitan areas, focusing on electromagnetic compatibility issues in urban environments. The study represents early military recognition of the growing electromagnetic pollution in cities from various radio frequency sources. This research helped establish foundational understanding of urban EMF exposure patterns that remain relevant today.
Peter G. Thomas · 1972
This 1972 research examined the safety of microwave ovens for consumer use, focusing on potential radiation leakage and health risks. The study was conducted during the early years of microwave oven adoption when the FDA was establishing safety standards for these appliances.

Sol M. Michaelson · 1972
This 1972 study examined how humans perceive microwave radiation through skin sensations, finding that people can feel warmth from microwaves within 1-4 seconds at specific power levels. Researchers established thermal sensation thresholds for 3,000 MHz and 10,000 MHz frequencies when applied to facial skin areas. The study showed that microwave perception occurs through the body's natural heat-sensing mechanisms.

This 1972 review examined microwave radiation hazards from radar systems and early microwave ovens, finding proven lethal effects in animals and cataract formation in humans. The study warned about increasing commercial and domestic microwave use creating new exposure risks, especially for people with medical implants like pacemakers.
Jeffrey McCullough et al. · 1972
This 1972 medical study documented cases where microwave devices used to warm blood for transfusions caused hemolysis (destruction of red blood cells). The research identified microwave heating as a cause of iatrogenic complications, meaning medical treatment-induced problems that harmed patients during blood transfusion procedures.

This 1972 study examined 25 years of research on microwave-induced cataracts in animals and humans.

Researchers tested five different cardiac pacemaker models in dogs exposed to 3050 MHz microwave radiation to see if the devices would malfunction. Most pacemakers experienced electromagnetic interference under certain conditions, with the most sensitive unit failing at around 100 volts per meter of exposure. One pacemaker model showed no interference effects throughout all testing.

Researchers exposed 749 pregnant rats to short-wave radiofrequency therapy during early pregnancy, causing body temperatures to reach 42°C (108°F). The heat exposure resulted in numerous birth defects and embryo deaths, with the type of malformation depending on when during pregnancy the exposure occurred.
