Behavioral effects of microwaves relationship of total dose and dose rate
The goal of this research was to compare the relationship of wholebody averaged specific absorption rate (SAR) and specific absorption (SA) to determine if dose rate or dose was a better predictor of biological effects. Sperm positive Long-Evans female rats were exposed to approximately 10 W/kb for 1 or 3 hours to 2450 MHs CW microwaver ratiation. The maternal subjects were irradiated and then observed for natural delivery of their litters. The resultant pups made up the subject pool for the behavioral studies. Sensitivity to thermally induced seisures and huddling were studied. Analyses revealed that there were no statistically significant differences on the behavioral indices. The behavioral measures did not appear to be effected by prenatal exposure to microwave radiation at this level. The huddle sises did become smaller as the pups aged and the two different huddle measurements employed differed in the proportion of variance accounted for by the age of the pups.
