Abstract:
In this experiment mice were irradiated by 36.11 GHz millimeter wave at a power density of 10.0mW/cm~2 for 2 hours daily from the 6th to 15th day of gestation. The postnatal fetus was evaluated by psychophysiologic indexes. The data analysis indicated that millimeter wave radiation significantly delayed appearance time of 3 reflexes in each litter but had no effects upon 4 physiological indexes. Millimeter wave radiation lowered the learning capacity and memory of the offspring mice, which committed a higher quantity of errors and needed more training than the control group. The criteria of conditioned reflex were set by using Y-type electric maze. In addition, this experiment found no obvious effect on swimming endurance of the offspring, and a marked drop in the body weight of the offspring from 1st day to 8th week. These results indicated that exposure to millimeter wave radiation on the postimplantation embryos may result in subtle long-term neurophysiologic alterations.
