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.

Scientists in 1972 used a superconducting magnetometer in a shielded room to measure magnetic fields produced by human skeletal muscles, called magnetomyograms (MMGs). These muscle-generated magnetic fields come from the same electrical currents that create surface electromyograms (EMGs), but MMGs can detect slower electrical changes that EMGs cannot. The research measured these natural magnetic fields near the elbow and palm.

Researchers exposed human blood plasma to 2450 MHz microwave radiation (the same frequency used in microwave ovens) at power levels up to 280 mW/cm² for up to 24 hours. They found no significant changes in blood clotting processes, platelet count, or clot strength when temperatures stayed below body temperature. Interestingly, microwave heating to 37-42°C caused less blood clotting disruption than conventional heating to the same temperatures.

Polish researchers exposed 24 rabbits to microwave radiation (0.1 cm wavelength) for up to 124 hours and found significant eye damage. The microwaves heated the vitreous fluid inside the eyes and caused microscopic lens damage including cell death, structural changes, and capsule thinning. This demonstrates that prolonged microwave exposure can cause cataracts through both heating and direct cellular damage.
