A single sub-lethal exposure to a mean of 7.2 watts forward power of 2450 MHZ microwave radiation for 4 minutes of pregnant mice on gestation days 0 to 11 inclusive showed that when all damage to implantations was considered, that gestation day 8 showed 68% of all embryos damaged when compared with the controls showing only 22% failed to develop normally. This included dead and resorbed embryos and surviving anomalies of a gross nature. The prime effect on days 3 and 10 was killing. When anomalies alone were considered it was found that days 4 and 8 showed definite but minimal statistically significant increments when compared with the controls, the primary anomalous condition being stunting. There was no statistical significance in the resorption data. This differential effect at different gestation days might indicate a different thermal sensitivity of embryos stressed with thermal levels of radiation.
