Aim of study (acc. to author)

Rats, with their fur clipped, were trained to press a lever to turn on an infrared lamp for 2 seconds while in a cold chamber. The aim was to study the effects of 2450 MHz continuous wave (CW) microwaves on thermoregulatory behavior.

Main outcome of study (acc. to author)

When the rats were exposed to continuous wave microwaves at 2450 MHz, the rate at which they turned on the infrared lamp decreased as a function of the power density (which arranged between 5 and 20 mW/cm²).
