Primate-Performance Assessment Following 3.2-GHz Exposures.

Performance data were obtained from 2 rhesus monkeys exposed to 3.2-GHz 50-microsec square wave pulses at 4000 pps with an average transmitter output power of 200 W. Subjects were exposed for 3 hours per day in a continuous exposure for 7 days. The root-mean-square value about the mean was measured from a Primate Equilibrium Platform in which the subject was trained to use a control stick to maintain the platform in a level position in the pitch axis. Comparisons were made with baseline measurements of 8 animals in a similar experiment. No performance decrements were evidenced in this pilot study, and ophthalmic examinations completed 22 months postexposure showed no abnormalities. (Author)
