This study examined lethal microwave exposures 240 times higher than cell phones, finding frequency-dependent heating patterns but no unusual cardiovascular responses.

Plain English Summary

Summary written for general audiences

Researchers exposed anesthetized rats to microwave radiation at 1 GHz, 10 GHz, or both frequencies combined at high power levels (12 W/kg) until the animals died from overheating. They found that rats exposed to 1 GHz died fastest, while those exposed to 10 GHz survived longest, with combined exposure falling in between. This study was designed to understand how different microwave frequencies affect heat distribution in the body and cardiovascular responses during extreme thermal stress.

Study Details

This study compares the thermal distribution and cardiovascular effects of exposure to a single MW frequency with effects of simultaneous exposure to two frequencies.

Ketamine-anesthetized male Sprague-Dawley rats (n = 58) were exposed individually to one of three co...

In both E and H orientations, survival time (i.e., time from colonic temperature of 37.5 degrees C u...

The results indicate that no unusual physiological responses occur during multi-frequency MW exposure, when compared with results of single-frequency exposure.
