Behavior and Temperature of Rhesus Monkeys Exposed to Low Level Microwave Irradiation.
Abstract
Male rhesus monkeys, trained to respond on an auditory vigilance task, were exposed to vertically polarized 2450 MHz microwaves in an anechoic room. Power densities of 4, 16, 32, 42, 52, 62, and 72 mW/sq cm, and exposure times of 30, 60, and 120 minutes were used. The monkeys performed the vigilance task in a styrofoam restraint chair while irradiated from the front. Body temperature was monitored during exposure at all but the lowest power density. Vigilance performance was not affected until 72 mW/sq cm illuminations occurred. Colonic temperature increase appeared to be a logarithmic function of power density from 16 to 72 mW/sq cm, whereas no such relationship was observed with behavioral indices. The animals showed adaptation to the microwaves in both behavioral and thermal measures, and thermal equilibrium was obtained except at 72 mW/sq cm. (Author)
