Researchers discovered that the human head acts like an antenna at 350 MHz microwave frequency, absorbing three times more energy than expected. This "head resonance" effect means the head region absorbs far more radiation than previously calculated when the whole body is considered, not just the isolated head.

Researchers exposed chicken eggs to electromagnetic fields of up to 160 gauss for 3 seconds each before incubation, then measured hatching rates and chick weights. The study found no effects on hatchability, body weight, or hatching time, contradicting a U.S. patent's claims that similar EMF exposure improves hatching success by 5-8%.

Researchers exposed chickens to extremely high electric fields (30 kV/m at 50 Hz) for 43 weeks, from hatching through their first laying period. While egg production remained normal, exposed birds showed behavioral changes including increased aggression in roosters and abnormal nesting behaviors in hens. The study found no effects on fertility or offspring development, but egg weight gain was reduced in the exposed group.

Researchers tested how much radiofrequency energy from 800 MHz portable radio transmitters gets absorbed into simulated human tissue, particularly near the head. They found that different antenna designs create "hot spots" about 1 inch below the temporal bone, with some antennas exposing the eye area to higher energy levels. The temperature increases were small enough that researchers concluded normal radio use shouldn't cause thermal tissue damage.
