Behavioral Effects of 1300 MHZ High-Peak-Power-Microwave

Abstract

Results of behavioral and physiological studies on the effects of high-peak-power microwaves (HPPM) are reported. Rats were typically irradiated for 10min using the following HPPM characteristics: 1300MHz, 10 MW power, 5 and 10 pulses per second (pps), 1.8 kW/cm2 peak-power density with 1, 5, or 10 microseconds pulse widths. Average-power densities were 9, 45 and 90 mnW/cm2 at 5 pps and 18, 90 and 180 mW/cm2 at 10 pps (average colonic specific absorption rate (SAR) = 1.8, 6.5, 13.1 W/kg and 3.6, 13.1, and 26.2 W/kg, respectively). Results indicated the following: (1) Irradiation under 10 microseconds/10 pps protocol (SAR = 26.2 W/kg) reduced locomotor activity. (2) Response rates under a variable-interval (VI schedule declined after irradiation protocols yielding SARS greater than 13.1 W/kg. Keywords: High-peak-power-pulsed microwave; Psychology, Learning, Electromagnetic radiation; 1.30 GHz; Operant conditioning; Memory processing; Discrete trial avoidance behavior.
