Female Sprague-Dawley (CD) rats were exposed to 2450-MHz (CW) microwave radiation at incident power densities of 0 or 40 mW/sq. cm. (SAR = 6.0 W/kg) for 100 min daily on the sixth through 15th day of gestation. One-time exposure to the same conditions increased average colonic temperatures 2 C at the end of irradiation in pregnant rats of similiar size. There were 23 sham-irradiated and 24 microwave-irradiated females. When these groups were compared on the 21st day of gestation, no significant differences were found in pregnancy rates; in the numbers of live, dead or total fetuses; nor in the incidences of external visceral or skeletal anomalies or variations. However, mean fetal body weight was significantly (p=0.00008) lower after microwave irradiation and was 9% less than that of sham-irradiated litters.
