Abstract

Research has been carried out to investigate the effects of pulsed microwave exposure without pause (7 GHz, 400 pps, 100 microseconds, 70-150 mW/cm2, exposure 10 min) and pulsed interrupted cyclical microwave exposure (5 min exposure--4 min pause--5 min exposure) on learned behaviors of rats in the paradigm of extraordinary situation (the rescue of the life). It was shown that reductions in conditioned behavior after acute pulsed microwave exposure occurred at SAR of 21 W/kg (100 mW/cm2) and after cyclical pulsed microwave exposure at SAR of 28.4 W/kg (135 mW/cm2).

Main findings

Reductions in conditioned behavior after acute pulsed microwave exposure without pause were observed at SAR 21 W/kg (100 mW/cm2). Reductions after interrupted cyclical pulsed microwave exposure were observed at SAR 28.4 W/kg (135 mW/cm2).

Outcomes measured

learned/conditioned behavior in an extraordinary situation paradigm (rescue of life)

Limitations

Sample size not reported in abstract.
Only acute exposures described; longer-term effects not addressed.
Exposure conditions are high (SAR values in tens of W/kg), which may limit generalizability to lower-level exposures.
