Behavioral sensitivity to microwave irradiation med./bio.

Published in: Science 1971; 172 (981): 398-401

Aim of study (acc. to author)

To assess in rats the efficacy and the reliability of modulated microwaves as a warning stimulus for impending electrical shock.

Time of investigation:
  • during exposure
  • after exposure

Main outcome of study (acc. to author)

Rats were able to detect the presence of the microwaves at doses of power approximating 0.5 to 6.4 mW/g. Efficiency of detection was strongly related to the amount of microwave energy to which the animals were exposed.
