Abstract :
Results of behavioral and physiological studies on the effects of high-peak-power microwaves (HPMs) are reported. Rats were typically irradiated for 10 min using 1300-MHz microwaves with 10-MW forward power, 5- and 10-Hz pulse repetition frequency, 1.8-kW/cm2 peak-power density with 1-, 5-, or 10-μs pulse widths. Results indicated that irradiation reduced locomotor activity and response rates under a variable interval schedule but did not disrupt discrete-trial avoidance or escape response. A single 10-min exposure caused deficits in memory processing and caused rats to form an aversion to the site of irradiation. The results of these experiments establish a preliminary threshold of HPM irradiation sufficient to produce behavioral effects consistently
