Model		918 MHz (CW) exposure to rats and analysis of learned avoidance behavior
Details		Long Evans rats were exposed to 918 MHz (CW) MW at 60 W/kg during 25 x 2 minute exposure periods (5 per day). Rats failed to learn to escape from this potentially lethal dose of MW. In other studies, rats were exposed to photic stimulation or Farady shock and allowed to escape into a MW chamber where they were alternatively exposed. While shock and light triggered escape behavior into the MW chamber, alternate MW exposure did not consistently trigger escape into the shock or light chamber. The authors conclude that potentially lethal thermal MW exposure lacks the sensory quality to motivate efficient escape behavior in rats. In an earlier study, however, Sprague-Dawley rats were exposed to 2450 MHz (PW) MW for 10 seconds at SARs of up to 430 W/kg and analyzed for learned behavior avoidance. At this high level of MW exposure that increased core temperature by 0.7 degrees C in 10 seconds, a learned avoidance behavior could be demonstrated.
