This 1976 study examined why people hear sounds when exposed to pulsed microwave radiation, a phenomenon known as the microwave auditory effect. Researchers compared three possible mechanisms and found that thermal expansion (rapid heating and cooling) in the head likely creates the perceived sounds. The study helps explain how microwave energy can directly stimulate auditory sensations without sound waves.

This 1976 study analyzed how plastic restraining devices used to hold laboratory animals during microwave experiments scatter and amplify microwave radiation. Researchers found that these supposedly "low-loss" materials created highly uneven radiation patterns, with some areas receiving nearly twice the intended exposure levels.

This 1976 study exposed mice to microwave radiation at different dose rates and found that slower exposure rates required higher total doses to cause death. The research demonstrated that both the rate of microwave absorption and total dose matter for biological effects, not just the total amount absorbed.

This 1976 technical report documented the specifications and calibration procedures for digital power meters designed to measure RF and microwave power levels. The instruments were capable of measuring power in dBm units across various frequencies, providing precise measurement tools for electromagnetic field assessment. Such equipment became essential for accurately quantifying RF exposure levels in research and regulatory contexts.

Scientists exposed rabbit eyes to 2.45 GHz microwave radiation (the same frequency used in microwave ovens and WiFi) at levels known to cause cataracts. They found the radiation disrupted normal cell division in the eye lens, either suppressing it initially or causing abnormal increases later, depending on the severity of lens damage.

Researchers exposed isolated turtle hearts to 960 MHz microwave radiation and found it caused the heart rate to slow down (bradycardia) at specific power levels between 2-10 mW/g. This effect appeared to work through nerve pathways rather than simple heating, since higher power levels that caused heating actually increased heart rate instead.
Roberts Rugh · 1976
Researchers exposed 114 male and female mice of different ages to lethal doses of 2450 MHz microwave radiation to determine sensitivity differences. They found that older mice survived longer under constant exposure, but the total energy dose needed to cause death remained similar within each sex. Male mice consistently required higher radiation doses to die compared to females across all age groups.
