This 1979 French technical study examined microwave heating and thermography for medical and industrial applications. Researchers developed automatic probe-applicators (open waveguide sections) and found that microwave penetration depth depends on both the material's properties and the probe characteristics. The work laid groundwork for combining microwave heating with thermal imaging technology.

Researchers exposed newborn mice to 148 MHz radio frequency radiation for one hour daily over 10 weeks, then monitored them for nearly two years. The study found no differences in blood parameters, body weight, or disease rates between exposed and control animals at the power levels tested.
M. Wayne Greene et al. · 1979
This 1979 educational course covered the fundamental science of how microwave radiation interacts with living tissue, documented biological effects, and safety standards for protection. The course addressed both the mechanisms of microwave bioeffects and practical approaches to measuring and limiting exposure to potentially harmful electromagnetic fields.
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.

Researchers exposed rats to 60 Hz electric fields at household power line frequencies for 30 days, testing field strengths from 0 to 1000 V/m. They found subtle changes in nighttime activity patterns and morning alertness at the highest exposure level, but no significant effects on body weight, organ function, or blood chemistry.
Pierre Aigrain · 1979
This 1979 Monaco symposium brought together researchers to discuss microwave energy applications beyond telecommunications, including industrial heating, medical uses, and domestic appliances. The proceedings emphasized the need for continued research into how microwaves interact with living matter as these technologies expanded into everyday use.
T. Dan Bracken · 1979
This 1979 workshop proceedings documented early research discussions on biological and electrical effects from high-voltage direct current (HVDC) power transmission systems. Scientists examined how static electric fields and air ions from these power lines might affect human health. The workshop represented one of the first systematic attempts to understand potential health impacts from this emerging power transmission technology.

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.
Zorach R. Glaser · 1979
This 1979 memorandum documents a meeting of the Technical Electronic Product Radiation Safety Standards Committee, a government body responsible for setting RF radiation safety standards. The document represents early regulatory discussions about radiofrequency radiation safety protocols during the emergence of widespread electronic device use.
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.

Researchers exposed rats to low-level pulsed microwave radiation at 1 milliwatt per square centimeter while giving them chlordiazepoxide, a sedative drug. The microwave exposure made the drug's behavioral effects stronger, even though the radiation alone had no apparent impact on the rats' behavior.
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.

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.
