Presman AS, Levitina NA · 1961
This 1961 study by Presman examined how microwave radiation affects heart rhythm patterns in animals, focusing specifically on nonthermal effects that occur without heating tissue. The research was groundbreaking for its time, investigating whether microwaves could disrupt normal cardiac function through biological mechanisms beyond simple tissue heating. This early work helped establish that electromagnetic fields could influence vital physiological processes at exposure levels previously considered safe.

This French research study examined internal organs and reproduction in mice and rats exposed to pulse-modulated ultra-short waves at 3105 MHz, with modulation chosen to avoid heating. It reported no characteristic visceral lesions (tissue damage to internal organs) and no pathological change in reproduction. The only finding noted was slightly enlarged, congested spleens, which the authors link to a possible excitation of the reticulo-histiocytic system.

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.

Researchers exposed six volunteers to 220 MHz radio waves for 45 minutes at power levels similar to radio transmitters. The exposure triggered vigorous sweating and increased blood flow even with minimal body temperature changes, showing that radiofrequency energy directly activates the nervous system's temperature control mechanisms.

Researchers evaluated three BRH applicators and four microwave hyperthermia applicators by thermographically analyzing them using planar phantoms, measuring leakage radiation, net power required to deliver 235 W/kg SAR, and heating patterns. The BRH 2450 MHz applicator had less than 5 mW/cm² leakage for both direct contact and 1 cm spacing, while the 915 MHz applicators exceeded that level when spaced 1 cm from the phantom. The depth of penetration into muscle tissue was nearly identical for both frequencies, at about 2 cm beneath the fat-muscle interface.

Russian scientists exposed blood samples to high-frequency radiation (32.9-39.6 GHz) for 15 minutes and found neutrophils (infection-fighting white blood cells) responded more aggressively to bacterial threats. The enhanced immune response was caused by heating effects, showing electromagnetic radiation can amplify immune system activity.

Italian researchers exposed human immune cells (lymphocytes) to microwave radiation at frequencies of 2.45 and 7.7 GHz to see if it would damage their DNA. They found that high-power exposures (30 mW/cm²) for 30 and 60 minutes caused significant genetic damage, creating abnormal cell structures called micronuclei that indicate DNA breaks. This matters because it demonstrates that microwave radiation can directly damage human genetic material under laboratory conditions.

Researchers exposed human peripheral blood lymphocytes in vitro to electromagnetic fields at two frequencies, 2.45 and 7.7 GHz, at power densities of 10, 20, and 30 mW/cm2 for 15, 30, and 60 minutes. At a power density of 30 mW/cm2 and after exposures of 30 and 60 minutes, both frequencies led to an induction of micronuclei compared to control cultures. The researchers concluded that microwaves are able to cause cytogenetic damage in human lymphocytes mainly for both high power density and long exposure time.

Researchers exposed rabbits and monkeys to 60 GHz millimeter wave radiation at 10 mW/cm² for either 8 hours straight or 4 hours daily for five days, then examined their eyes for damage using microscopes. They found no detectable eye damage from either exposure pattern. This suggests that millimeter wave radiation at this power level doesn't cause immediate eye injury in laboratory animals.
