Mortality in Rats Exposed to CW Microwave Radiation at 0.95, 2.45, 4.54,and 7.44GHz.

摘要

Dose-response (lethality) data have been obtained for rats exposed frontally to CW microwave radiation in the frequency range 0.9to 8GHz. Approximately 1400male rats of the Sprague-Dawley strain have been exposed groups to four separate frequencies: 0.95, 2.45, 4.54,and 7.44GHz. Power density levels have ranged from approximately 0.2 W/sq cm to 12 W/sq cm,and lethal exposure durations from approximately 10sec to 300sec. Gross and histologic evaluation of selected tissues from some 20animals has been obtained. The cause of death has been established as congestion,hemorrhage,and obstruction of nasal passages and/or congestion,hemorrhage,and often edema of the lungs. The lethality data have been subjected to a probit analysis,yielding LD50curves for each of the four frequencies,and the LD50values have been empirically fitted with a mathematical model.
