To study the effects of microwave irradiation on escape behavior of rats.
Rats received 25 2-min trials of training under one of four stimulus conditions: exposure to a highly intense 918 MHz field (dose rate, 60 mW/g); exposure to photic stimulation; exposure to the field in synchrony with photic stimulation; or exposure to faradic shock (i.e. by electric current). During conditioning trials, entry by a rat into a safe area of a multimode cavity resulted in immediate and complete cessation of stimulation; exit, in resumption.

Additional info | 4 groups were used in this study; One group served as active control which received faradic shocks to the feet, the other groups were either microwave exposed or received photic stimulation or both. |

Acquisition of the escape response was rapid and highly efficient for shocked rats and was less rapid and efficient but was reliably demonstrated by exposed animals that were also signaled by light. In the absence of microwaves, cessation of light did not reliably motivate escape behavior. Although there was weak evidence of escape learning by animals subjected only to microwave irradiation, their performance failed to differ reliably from those of rats in the light-only condition. These results confirm and extend those of Carroll et al. (publication 88), which indicate that potentially lethal, deeply penetrating, nonpulsed microwaves in a multipath field lack the sensory quality to motivate efficient aversive behavior by the rat.
