H.P. Schwan · 1979
This 1979 historical review by researcher HP Schwan examined four decades of microwave bioeffects research from the 1930s onward. Schwan concluded that scientifically-grounded research approaches had been most productive, while purely experimental studies lacking theoretical foundation proved less useful. The review suggested that enough evidence existed by 1979 to establish rational safety standards for microwave exposure.

Scientists tested whether pulse-modulated microwaves create the sensation of hearing sounds by converting electromagnetic energy to acoustic waves in the skull. Using advanced holographic imaging, researchers found that the predicted tissue movements in the head did not occur, ruling out this proposed mechanism. This challenges our understanding of how microwave energy might interact with human hearing perception.
L. Hellemans, M. De Maeyer, R. Ooms · 1979
This 1979 study examined how high-strength electric fields (100,000 volts per centimeter) disrupt hydrogen bonds in chemical systems, using frequencies from 1-100 MHz. Researchers found that these intense fields could break apart molecular bonds that normally hold proteins and other biological structures together. The findings matter because they demonstrate a fundamental mechanism by which electromagnetic fields can alter biological processes at the molecular level.

Allan H. Frey, Elaine Coren · 1979
Researchers tested whether pulsed microwave radiation creates sound perception by causing skull vibrations, as previously theorized. Using advanced holographic imaging, they found the skull doesn't vibrate as predicted, disproving this mechanism. The study suggests the microwave hearing effect must occur through a different biological pathway.
Zory R. Glaser · 1979
This 1979 technical conference paper by Glaser examined radiofrequency sealers, heaters, and gluers used in industrial applications. The research focused on dielectric heating equipment that uses RF energy to bond, seal, or heat materials in manufacturing processes. This work provided early documentation of industrial RF sources that create occupational EMF exposures.
Charles L. Sheridan et al. · 1979
This 1979 study exposed mice to near-lethal doses of 2450 MHz microwave radiation while in the womb and tracked their lifespan over three years. The research found that exposed mice actually developed fewer tumors than unexposed controls, though the difference was too small to be statistically meaningful. The study also discovered that intense microwave exposure causes dangerous overheating but animals cannot sense the radiation to escape it.

This 1979 conference paper documents an annual meeting and workshop focused on microwave cooking appliances, organized by the Cooking Appliance Section of IMPI (International Microwave Power Institute). The gathering brought together industry professionals to discuss technical aspects and developments in microwave cooking technology during the early years of consumer microwave adoption.
M. J. Ortner et al. · 1979
This 1979 study examined how 2450 MHz microwave radiation affects mast cells (immune cells involved in allergic reactions) in rat abdominal cavities. The research focused on understanding how microwave exposure at this specific frequency impacts these important immune system components. This frequency is significant because 2450 MHz is used in microwave ovens and some industrial heating applications.
Thomas F. Budinger · 1979
This 1979 study by researcher Budinger established safety thresholds for NMR (nuclear magnetic resonance) imaging, which later became MRI technology. The research identified specific limits for RF power, static magnetic fields, and field variation rates that would prevent health hazards in medical imaging. These early guidelines helped shape safety protocols still used in modern MRI facilities.

Researchers exposed growing rats to pulsed microwave radiation at 2,736 MHz for 7 weeks and found significant changes in blood composition, including reduced white blood cell counts and lower hematocrit values. The blood changes gradually disappeared within 10 weeks after exposure ended, but the rats showed slower weight gain during recovery.
