Abstract

The aftereffects of high-power pulsed microwave radiation were studied on adult Wistar rats trained to perform a lever-pressing task to receive a food pellet. Each trained animal was exposed to a 1-MW peak-power microwave field for 10 min. Whole body dose rate levels were adjusted by using different pulse repetition rates. Only animals exposed at the highest dose level failed to respond immediately after exposure, and this was associated with elevated rectal temperatures. They started responding when their rectal temperatures dropped to pre-exposure levels. It is concluded that these behavioral aftereffects are thermal in nature
