Heat-dissipation rate of mice after microwave irradiation

The heat dissipation rate from individual CF1 male mice was determined by a bio-calorimeter before and after exposure to microwave radiation. The animals were irradiated singly in an environmentally-controlled waveguide apparatus with 2450 MHz CW microwave radiation. The incident power levels were 0 (sham), 0.4, 0.8, 1.7 and 3.3 W, which resulted in corresponding mean average absorbed dose rates of 0 (sham), 7, 12, 27 and 39 mW/g. The environmental conditions were 24 degrees C temperature, and 50% relative humidity. The results indicate an increased heat-dissipation rate of the animals (compared to sham) for average absorbed dose rates above 12 mW/g.
