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.

Researchers exposed 90 adult salamanders to static electrical charges ranging from 0 to 500 volts to test whether electrical fields affect limb regeneration after amputation. After 35 days, they found no consistent differences in regeneration rate or quality between any voltage groups, including controls.

Researchers investigated why electrical stimulation through the skin often causes sharp, pricking pain. They discovered the pain results from thermal damage to the skin's outer layer caused by high energy concentrations at uneven skin-electrode contact points. The study found this pain can be controlled through proper electrode application techniques without using conductive gels.

This 1976 technical study analyzed how signal timing affects Doppler flow measurement systems used in medical diagnostics. Researchers found that random signal Doppler systems produce the same output as pulsed RF Doppler systems when properly calibrated. The work focused on improving medical ultrasound and flow measurement technology rather than health effects.

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.

Researchers used 2450 MHz microwaves (the same frequency as microwave ovens) to heat tumors in mice, finding that 200 watts was barely enough to warm small tumors. They developed a technique combining warm air with microwaves to achieve therapeutic heating levels more efficiently and uniformly.

This 1976 NIOSH technical report documented the development of specialized equipment to create and measure radiofrequency electromagnetic fields in the 10-40 MHz range for research purposes.

This type of instrumentation was essential for early occupational health research into RF radiation effects on workers.

Researchers used scale models and thermographic imaging to measure how much radiofrequency energy the human body absorbs when exposed to high-frequency electromagnetic fields. They found that exposure to 31 MHz radiation at 10 mW/cm² can create power absorption densities as high as 5.63 W/kg in certain body regions. This pioneering 1976 study helped establish methods for measuring EMF absorption that are still used today.

Researchers exposed rats to 1.6 GHz microwave radiation for 10 minutes, causing a 4°C temperature rise and measuring brain neurotransmitter changes. The radiation decreased key brain chemicals including norepinephrine, serotonin, and dopamine - effects that went beyond simple heating. This suggests microwave radiation can directly alter brain chemistry in ways that temperature alone cannot explain.

Researchers exposed rodents to intense electromagnetic pulse (EMP) radiation for 94 weeks, delivering 250 million pulses at extremely high field strength (447 kV/m). Despite this massive exposure, scientists found no biological effects on blood chemistry, chromosomes, fertility, or tumor development. This 1976 study suggests rodents can tolerate very high levels of pulsed electromagnetic radiation without measurable harm.
