S. O. Nelson · 1972
This 1972 research investigated using various forms of electromagnetic energy as a method for controlling stored-product insects. The study examined different types of electromagnetic radiation including microwaves, radio waves, infrared, and ultraviolet radiation for their potential to manage pest insects in agricultural storage facilities.
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.
Charles Merckel · 1972
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.
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.
Sol M. Michaelson · 1972
This 1972 study examined 25 years of research on microwave-induced cataracts in animals and humans. Researchers found that 100 mW/cm² for one hour was the lowest threshold to cause cataracts in rabbits at frequencies between 2450-10,000 MHz. Human cases showed cataract formation only at very high exposure levels well above 10 mW/cm².
William D. Hurt, M.S. · 1972
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.
F. G. Hirsch, M.D. and A. Bruner, Ph.D. · 1972
This 1972 study by Hirsch tested whether electromagnetic pulses (EMPs) from a Van de Graaff generator caused biological effects in monkeys and dogs. The research found no observable effects from the EMP exposures. This early work helped establish baseline data on high-intensity, short-duration electromagnetic field exposure in mammals.
Jeffrey Frey, Raymond Bowers · 1972
This 1972 technical paper examined the emerging concerns about microwave technology expansion as solid-state power sources made microwave devices cheaper and more widespread. The author highlighted two key issues: spectrum allocation challenges and potential health hazards from increased microwave exposure. This early analysis predicted the proliferation of microwave applications we see today.
A. Frey, R. Messenger, E. Eichert · 1972
This 1972 study by researcher Allan Frey investigated the "RF sound phenomenon" where people hear sounds when exposed to radiofrequency energy directed at their heads. The research successfully created a portable device to demonstrate this effect and explored whether RF energy could generate perceived speech, finding that traditional speech synthesis methods didn't work for RF-induced sounds.
Dietzel F, Kern W, Steckenmesser R · 1972
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.
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.
