Abstract
Behavioral sequelae of exposure to high peak power microwave pulses, similar to those produced by operational radar systems and experimental, directed energy weapons systems, were studied using rats trained on fixed-ratio, variable-interval, and differential reinforcement-of-low rate schedules. Ten minute exposures to 240, 720, 2160, and 6480 pulses at a 1 Megawatt peak power level caused a rectal temperature rise of 0.7 to 2.5°C in the animals. Regardless of their schedule of reinforcement, animals exposed to the highest dose level failed to respond, on the average, for 13 minutes after the exposure when they were placed in operant conditioning chambers. However, as soon as their rectal temperatures decreased, responding resumed and no further changes in response pattern were exhibited. No long-term effects were observed in exposed animals. Thus, the behavioral effects that were seen were thermal in nature and independent of the pulsed nature of the fields.
