This 1972 technical report investigated how microwave radiation at levels considered 'safe' by regulatory standards could affect sensitive portions of the human central nervous system. The research focused on identifying which parts of the brain and nervous system might be vulnerable to microwave exposure even at officially approved power levels. This early work helped establish that some biological systems may be more susceptible to electromagnetic effects than others.

This 1972 study examined allegations that low-intensity microwave radiation was used to induce 'asthenic syndrome' (fatigue, weakness, and cognitive impairment) during the famous Fischer-Spassky chess championship. The research investigated whether microwave exposure could deliberately cause neurological symptoms as suggested in the Cold War-era chess match controversy.

This 1972 study exposed baby chicks to various electromagnetic fields including UHF (880 MHz), VHF (260 MHz), and low-frequency electric and magnetic fields for 28 days. Chicks exposed to 880 MHz UHF signals showed significantly reduced growth rates, while those exposed to low-frequency electric fields also experienced growth depression. The findings suggest that even relatively low-power electromagnetic exposures can impact biological development in young animals.

This 1972 study exposed cats' heads to 915 MHz microwave radiation and measured changes in their nervous system responses to touch and sound. The researchers found that brain activity was altered at power levels around 5 mW/cm³, with temperature increases occurring alongside these neurological changes. This early research demonstrated that microwave radiation can directly affect central nervous system function in mammals.

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.
STANISLAW BARANSKI, M.D. · 1972
This 1972 study investigated whether low-level microwave radiation could cause brain tissue damage in rabbits and guinea pigs without heating effects.

L. I. Mishchenko, S. P. Frenkel · 1972
This 1972 study exposed rats to superhigh frequency electromagnetic fields and measured changes in brain chemistry, specifically nitrogen-containing compounds involved in brain metabolism. Researchers found that electric fields increased ammonia and glutamate levels in the brain, while magnetic fields decreased ammonia and glutamine but increased other metabolic compounds. The findings suggest that microwave-frequency EMF can alter fundamental brain chemistry in ways that could affect normal brain function.
F. A. Kolodub, H. I. Evtushenko · 1972
This 1972 study exposed rats to 7 kHz electromagnetic fields at different intensities (24 and 72 kA/m) for multiple sessions and up to six months. Researchers found significant disruptions in brain nitrogen metabolism, including altered ammonia levels and impaired cellular energy processes. The findings suggest that low-frequency electromagnetic fields can interfere with basic brain chemistry.

Researchers modeled electromagnetic wave heating in conducting spheres representing human heads of different sizes. They found that 10-cm radius spheres (adult heads) showed only surface heating above 1000 MHz, while smaller 4-cm spheres (child-sized heads) developed dangerous internal hot spots between 250-2800 MHz. This suggests children may face greater internal heating risks from radio frequency radiation.

Tyagin, N. V. (Nikolay Vasil'yevich) · 1971
This 1971 Soviet study examined workers exposed to Super High Frequency (SHF) microwave radiation and documented three distinct patterns of health effects: nervous system dysfunction, cardiovascular problems, and brain center disruption. The research identified that prolonged occupational exposure could cause irreversible health damage in some cases, though protective measures could prevent most harmful exposures.

Researchers exposed mealworm beetle pupae to 10 GHz microwave radiation and found that only 24% developed normally compared to 90% of unexposed controls. When they heated pupae to the same temperatures using regular heat instead of microwaves, 80% developed normally, proving the damage was caused by the microwaves themselves, not the heat they generated.
