Effects of Microwave Irradiation on Embryonic Brain Tissue.
Abstract
Several groups of dated pregnant rats were exposed starting on the 13th day of gestation in the anechoic chambers or in a calibrated oven. All the exposures to microwave irradiation were conducted after 0700 and before 1500 hours. The rats were sacrificed on the 19th day of gestation, the fetuses weighed and their brained fixed and serially sectioned. No differences were found between the irradiated fetuses and the controls which had been similarly handled but not irradiated. In a final experiment rats were exposed to irradiation from 1700 to 1900 hours or overnight (from 1800 to 0800 or 1000 hours) at 1700 MHz and 5 or 10 mw/sq cm, on the 6th to the 9th and the 12th to the 16th days of gestation. The exposed fetuses were heavier than the controls and the brains larger. The difference was approximately 10 percent. This finding suggests that the effect may be due to some factor which varies with the circadian rhythm. It may also have resulted from the earlier or the repeated irradiation.
