Susan Korbel · 1966
This 1966 technical report examined how ultra high frequency radio waves affected rat behavior, representing early research into microwave radiation's biological effects. The study investigated behavioral changes in laboratory rats exposed to UHF radiation. This research contributed to the foundational understanding of how radio frequency energy might influence living organisms beyond just heating effects.
Bryan, Robert N. · 1966
Researchers in 1966 exposed rats to microwave radiation immediately after training them in a shock-avoidance task. Rats that received microwave exposure retained their learned response 24 hours later, but rats that were handled before the experiment lost this memory despite being capable of learning. This suggests microwave radiation may interfere with normal memory consolidation processes.

Susan K. Eakin, William D. Thompson · 1965
Researchers exposed 20 male rats to UHF radio waves (300-920 MHz) for 47 consecutive days and tracked behavioral changes. The radiated rats initially became more active but grew less active over time, showed increased emotional responses, and took longer to recover from induced seizures. The study suggested these behavioral effects were non-thermal and related to changes in the nervous system.

The research explored whether these vitamins could modify the body's cardiovascular reactions to microwave-induced heating. This early work helped establish connections between microwave exposure, thermal stress, and potential nutritional interventions.
Susan Korbel Eakin, William D. Thompson · 1965
Researchers exposed 20 male rats to UHF radio waves (300-920 MHz) for 47 consecutive days and tracked behavioral changes. The radiated rats initially became more active but then grew less active over time, showed increased emotional responses, and took longer to recover from induced seizures. The study suggests these behavioral effects may be non-thermal and related to changes in the nervous system.
L. Cieciura, L. Minecki · 1964
This 1964 Polish study exposed rats to microwave radiation at high power levels (64-94 mW/cm²) and found significant decreases in enzyme activity specifically in the reproductive tissue of the testicles. The researchers concluded that microwaves directly affected enzymes crucial for sperm production, while leaving other tissues largely unchanged.
Horodets'ka SF · 1963
This 1963 Soviet research examined how centimeter-wavelength radio waves affected fertility in female mice. The study represents early scientific investigation into whether microwave radiation exposure could impact reproductive health in laboratory animals. This pioneering research helped establish the foundation for understanding EMF effects on biological systems.
Z. V. GORDON et al. · 1963
Soviet researchers in 1963 exposed rats to microwave radiation at intensities between 1-100 mW/cm² across wavelengths from millimeters to 10 centimeters. They found measurable biological effects including temperature changes, reduced swimming endurance, blood pressure alterations, nervous system impacts, and tissue damage even at the lowest intensity tested (1 mW/cm²). This early research demonstrated that microwave radiation could affect living organisms at power levels far below what causes heating.
R.A.E. Thomson, S.M. Michaelson, J.W. Howland · 1963
Researchers exposed mice to 2500 MHz pulsed microwave radiation, then subjected them to lethal X-ray doses 14 and 30 days later. The microwave-pretreated mice showed reduced death rates and longer survival times compared to mice that received only X-rays. This suggests microwave exposure may have protective effects against radiation damage.
S. Prausnitz, C. Susskind · 1962
Researchers exposed 200 male mice to microwave radiation daily for over a year at power levels that raised their body temperature by 3.3°C. The study found testicular damage and blood cell tumors in the irradiated mice, though overall lifespan wasn't significantly affected. This early research demonstrated that chronic microwave exposure could cause reproductive and cancer-related changes in mammals.
SUZY EAKIN, WILLIAM D. THOMPSON · 1962
Researchers exposed rats to low-intensity microwave radiation (450-965 MHz) for up to 60 minutes daily over 20 days and measured their spontaneous activity levels. The study found significant changes in rat behavior that only appeared after repeated exposures, suggesting cumulative effects from microwave radiation at power levels too low to cause obvious tissue damage.
L. CIECIURA, L. MINECKI · 1962
This 1962 Polish research examined how S-band microwave radiation affected testicular tissue in rats through detailed microscopic analysis. The study represents early scientific investigation into whether microwave frequencies could cause structural damage to reproductive organs. This research helped establish the foundation for understanding potential biological effects of microwave exposure.
A. N. Bereznitskaya · 1961
This 1961 study exposed female mice to 10-centimeter microwave radiation at 10 mW/cm² and found significant reproductive problems. The irradiated mice experienced disrupted menstrual cycles, partial sterility, increased stillbirths, and offspring with slower growth and development. This early research demonstrated that microwave radiation can harm female fertility and fetal development.
A. S. Presman, N. A. Levitina · 1961
Soviet researchers in 1961 exposed rodents to low-level microwave radiation before subjecting them to deadly gamma radiation. They found that microwave pre-treatment helped animals survive the otherwise lethal ionizing radiation exposure. This early study suggested microwaves could boost white blood cell counts and histamine levels, potentially offering protection against radiation damage.
C. Süsskind and Staff · 1961
This 1961 study by Susskind examined the long-term health effects of 3-centimeter microwave radiation on laboratory mice. The research focused on longevity impacts, tracking how extended microwave exposure affected the lifespan of test animals.

F. L. Leites, L. A. Skurikhina · 1961
Soviet researchers exposed 20 white rats to a single 10-minute microwave treatment and found significant changes in adrenal cortex hormone production lasting 1-2 weeks. The adrenal glands first released stored hormones into the bloodstream, then accumulated new hormone-producing substances in response to the radiation exposure.
