T. Daryl Hawkins et al. · 1973
This 1973 Walter Reed Army study exposed rats to 3000 MHz microwave radiation to test both lethal effects and behavioral changes. Researchers found that lower power densities required more total energy to kill rats than higher power densities, and discovered substantial frequency-dependent effects on rat behavior that could apply to other species including humans.
G. V. Galaktionova, A. D. Strzhizhovskiy · 1973
Researchers exposed mouse eye cells to permanent magnetic fields of 1,000 and 4,500 oersted for 10 to 180 minutes. The magnetic fields reversibly reduced cell division activity in a dose-dependent manner, with stronger fields causing greater effects. The cellular effects were temporary and did not cause genetic damage.

Researchers exposed isolated rat hearts to 960 MHz microwave radiation at power levels of 1.5 to 2.5 mW/cm³. Within two minutes, the hearts developed pronounced bradycardia (slowed heart rate) with both regular decreases and temporary cessations. This built on previous turtle heart studies showing similar cardiac effects from microwave exposure.

Koldaev VM · 1972
This 1972 Soviet research examined how microwave radiation affected rats exposed to altered atmospheric conditions, including different oxygen levels and chemical agents, with focus on antioxidant responses.

This represents early research into how multiple environmental factors might interact with EMF exposure.
V. M. Koldaev · 1972
Soviet researchers in 1972 exposed rats to 2380 MHz microwave radiation (12.6 cm wavelength) and then tested their survival when breathing oxygen-depleted air or given chemical treatments. The study found that microwave-exposed rats showed reduced resistance to these stressful conditions, with survival times correlating to the severity of chemical treatments and oxygen deprivation.
Blanchi, D., L. Cedrini, F. Ceria, E. Meda, G.G. Re · 1972
This 1972 study examined how strong 50 Hz electric fields (the frequency used in European power systems) affected mammalian test subjects, specifically looking at changes in white blood cells and electrical activity in the heart and brain. The research represents early scientific investigation into whether power frequency electromagnetic fields cause biological effects in living organisms.
R. O. Becker · 1972
This 1972 study by researcher Robert Becker investigated whether electrical stimulation could trigger partial limb regeneration in rats after amputation. The research explored how electrical currents might promote bone formation and tissue regrowth in mammals, which typically cannot regenerate lost limbs like some amphibians can.
Arthur W. Guy, Susan F. Korbel · 1972
Researchers measured how 500 MHz radiofrequency energy is absorbed in rodent-sized models placed in a laboratory exposure chamber. They found that actual absorption in the body was up to 1,000 times higher than what standard monitoring equipment indicated, with peak absorption varying dramatically based on the animal's position and posture.
F. A. Kolodub, G. I. Yevtushenko · 1972
This 1972 Soviet study examined how pulsed low-frequency electromagnetic fields (7 kHz) at industrial-strength levels affected rodents' biochemistry. The researchers found biological effects but noted that the underlying biochemical mechanisms causing these changes were poorly understood at the time.
William C. Milroy · 1972
This 1972 conference paper examined how microwave radiation affects the neuroendocrine system in rats, specifically looking at thyroid function. The research was part of early investigations into biological effects of microwave exposure on hormone-producing glands. While specific findings aren't available, this represents foundational work studying EMF effects on critical body systems.
William C. Milroy, Sol M. Michaelson · 1972
This 1972 study examined how microwave radiation affects thyroid function in laboratory rodents. Researchers investigated the pathophysiology (disease processes) of the thyroid gland when exposed to microwave energy. This research was among the early investigations into how radiofrequency radiation might disrupt hormone-producing organs.
Dietzel F, Kern W, Steckenmesser R · 1972
Researchers exposed 749 pregnant rats to a single short-wave treatment during the first 16 days of pregnancy, with short lasting rectal temperatures of 40°C. The high temperature treatment resulted in numerous birth defects and embryo deaths, with the type of malformation depending on when during pregnancy the exposure occurred.
F.A. Kolodub, G.I. Yevtushenko · 1972
Soviet researchers in 1972 exposed rodents to pulsed low-frequency electromagnetic fields and found significant disruptions in cellular energy production and metabolism. The study documented decreased ATP levels, impaired glucose processing, and toxic buildup of metabolic byproducts in heart, liver, and muscle tissues. These findings suggest that even low-frequency EMF exposure can interfere with fundamental cellular processes essential for life.
