Effects of pulsed microwaves at 1. 28 and 5. 62 ghz on rhesus monkeys (Macaca mulatta) performing an exercise task at three levels of work. Final report
Abstract
The present experiment studies both behavioral and physiological consequences of exposing exercising rhesus monkeys to microwave radiation. At 1.28 Ghz four of the monkeys were exposed to power densities of 25, 41, and 89 mW/sg cm. At the highest power density exercising animals consistently had a lower response rate, a higher heart rate, and a greater increase in colonic temperature. At lower power densities the effects were generally less evident and were idiosyncratic. At 5.62 GHz five monkeys were exposed to power densities of 25, 41, and 89 mW/sg cm. Differences from controls were found only at 43 mW/sq cm: (1) colonic temperature averaged +0.8 C higher (N=2), (2) response rate decreased (N=5) when the heaviest work load occurred during the terminal third of the session, and (3) heart rate (N=2) was higher. These experiments demonstrate the microwaves will produce cardiovascular effects in addition to those produced by exercise alone and that body temperature induced by microwave energy does not seem to be further accelerated by exercise. The results also illustrate that monkeys working a physically arduous task are more likely to stop working when exposed to microwave than when working a less arduous task.
