BODY HEATING INDUCED BY SUBRESONANT (350 MHZ) MICROWAVE IRRADIATION -CARDIOVASCULAR AND RESPIRATORY RESPONSES IN ANESTHETIZED RATS

These experiments were designed to investigate the effects of sub-reso nant microwave (MW) exposure (350 MHz, E orientation, average power de nsity 38 mW/cm(2), average whole-body specific absorption rate 13.2 W/ kg) on selected physiological parameters. The increase in peripheral b ody temperature during 350 MHz exposure was greater than that in earli er experiments performed at 700 MHz (resonance). Heart rate and mean a rterial blood pressure were significantly elevated during a 1 degrees C increase in colonic temperature due to 350 MHz exposure; respiratory rate showed no significant change. The results are consistent with ot her investigators' reports comparing sub-resonance exposures with thos e at resonance and above. (C) 1997 Wiley-Liss, Inc.
