Russian researchers exposed rabbits to low-intensity pulsed microwave radiation (1.5 GHz) for 30 minutes daily over one month and tracked their movement patterns. After two weeks of exposure, the animals began showing clear signs of behavioral disruption, including increased anxiety and alarm responses. This study demonstrates that even relatively weak microwave exposure can alter nervous system function when the exposure continues over time.

EPA researchers exposed female mice to 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) for one hour daily throughout their lives. Mice exposed to higher power levels lived significantly shorter lives - an average of 572 days compared to 706 days for unexposed mice, representing a 19% reduction in lifespan. This suggests chronic microwave exposure may accelerate aging or increase mortality risk.

Researchers studied blood cell counts in 14 radar technicians exposed to microwave radiation for 7-14 years, comparing them to unexposed airport workers. They found significantly lower counts of white blood cells, red blood cells, and platelets in the exposed workers. This suggests that chronic occupational microwave exposure may suppress the body's ability to produce healthy blood cells.
Joseph D. Bowman et al. · 1988
This 1988 study measured extremely low frequency (ELF) electromagnetic fields at 114 electrical worker job sites and compared them to residential exposures.

Przemyslaw CZERSKI, Stanislaw SZMIGIELSKI · 1975
This 1975 research review analyzed microwave radiation effects on biological systems through animal experiments and human occupational studies. The study found that high-dose microwave exposure causes heating effects, while chronic low-dose exposure produces unexplained effects on the nervous system and blood formation that can't be explained by heating alone. This early research highlighted gaps in understanding microwave health effects that remain relevant today.
A.S. HYDE, J.J. FRIEDMAN · 1975
This 1975 study exposed mice to 3 cm and 10 cm microwave radiation to examine effects on body weight and blood cell counts.
