Body heating induced by sub-resonant (350 MHz) microwave irradiation: cardiovascular and respiratory responses in anesthetized rats. med./bio.

Published in: Bioelectromagnetics 1997; 18 (4): 335-338

Aim of study (acc. to author)

To investigate the effects of microwave exposure (350 MHz, average power density 38 mW/cm², average whole-body specific absorption rate 13.2 W/kg) on selected physiological parameters (heart rate, mean arterial blood pressure, respiratory rate, body temperature).

Main outcome of study (acc. to author)

The increase in peripheral body temperature during 350 MHz exposure was greater than that in earlier experiments performed at 700 MHz. Heart rate and mean arterial blood pressure were significantly elevated during a 1°C increase in colonic temperature due to 350 MHz exposure. Respiratory rate showed no significant change.
