One hundred and eighteen male rats (Long-Evans) were acclimated to experimental procedures for 2 wk and then subjected to cage confinement for 3 days before microwave (MH) exposure to 2,450 MHz at 1 to 70 MW.cm-2 or sham exposure. Colonic temperature increased after exposure to power densities greater than or equal to 20 MW.cm-2 and was the most sensitive parameter measured. Inverse relationships between corticosterone and thyrotropin or growth hormone were noted after exposure for 1 h at 50 MW.cm-2 and above. Corticosterone, thyrotropin, and growth hormone levels could be correlated with power density or colonic temperature in rats exposed to MW for 1 h; corticosterone and thyrotropin levels correlated with colonic temperatures in shams.
