COL Budd Appleton, George C. McCrossan · 1972
Military researchers examined the eyes of personnel with the highest occupational microwave exposure levels alongside 135 unexposed controls, with examiners unaware of who had been exposed.

The study established threshold conditions based on body size, resistance, current duration, and pathway through the body.
Edward Gross · 1969
Scientists in 1969 examined how very low levels of microwave radiation might affect human health, including potential eye damage like cataracts.

The work helped establish the foundation for understanding subtle health impacts from everyday microwave sources.
K. MAJEWSKA · 1968
Researchers examined 400 people, comparing 200 microwave-exposed workers to 200 unexposed controls, finding evidence of harmful eye effects from occupational microwave exposure. The study showed that microwaves at levels considered safe by workplace regulations can cause eye damage when exposure continues for 4-5 years or longer. This early research provided some of the first human evidence linking chronic microwave exposure to health problems.
Afanas'yev BG · 1968
Soviet researchers studied ship specialists exposed to microwave radiation and found symptoms resembling adrenal insufficiency, including weakness, fatigue, and low blood pressure. The study examined how the hypothalamic-adrenal system responds to prolonged microwave exposure. This suggests microwave radiation may disrupt the body's stress response system.
V. G. CHALOV · 1968
Soviet researchers exposed 97 people to ultra-high frequency (UHF) radio waves at power densities of 10-100 microwatts per cm² over extended periods. The study found various pathological changes in the ear, nose, and throat organs, along with reduced ability to detect odors and decreased speech discrimination compared to unexposed controls.

This 1968 study examined how chronic microwave exposure affects brain function in rabbits, specifically looking at the electrical activity of brain synapses (the connections between nerve cells) using electroencephalography. The research was among the early investigations into whether microwave radiation could alter normal brain communication patterns in living animals.

Soviet researchers studied 100 workers exposed to microwave radiation for 10 years, finding progressive nervous system and heart problems. Early symptoms included fatigue, low blood pressure, and slow heart rate, with more severe changes developing over time. This landmark occupational health study demonstrated that prolonged microwave exposure causes measurable health effects in humans.
E. A. Drogichina et al. · 1966
Soviet researchers in 1966 studied 100 people chronically exposed to ultra-high frequency electromagnetic fields, documenting a progression of health effects from mild fatigue to severe cardiovascular problems.
