LACK OF BEHAVIORAL-EFFECTS IN NONHUMAN-PRIMATES AFTER EXPOSURE TO ULTRAWIDEBAND ELECTROMAGNETIC-RADIATION IN THE MICROWAVE FREQUENCY-RANGE

The effect of acute exposure to ultrawideband (UWB) electromagnetic ra diation on the Primate Equilibrium Platform (PEP) task, where the monk ey's task is to manipulate a joystick control to compensate for the ra ndom perturbations in the pitch plane that are generated by a computer at unpredictable intervals, was examined. The duration of the UWB exp osure was 2 min at a pulse repetition rate of 60 Hz (total of 7200 pul ses). The bandwidth of the pulse was 100 MHz to 1.5 GHz (peak power be tween 250-500 MHz) with a peak E-field strength of 250 kV/m. Each monk ey was exposed twice. The interval between exposures was 6 days. The e xposure to UWB electromagnetic radiation had no effect on PEP performa nce when tested immediately after exposure.
