Effects of Pregnancy Exposure to 1800 MHz Electromagnetic Irradiation on Hippocampus Ultrastructure of Offspring Rats / 环境与健康杂志

ABSTRACT

Objective To study effects of 1 800 MHz electromagnetic field exposure in pregnancy on the ultrastructure of the hippocampus of offspring rats. Methods Ninety Wistar rats(female and male was 21) were mated,and the pregnant rats were exposed to 1 800 MHz microwave field with power density of 0.5 mW/cm2 or 1.0 mW /cm2,12 h/d,for 21 consecutive days,the rats in the control group received dummy exposure. Three rats aged 3 days and 72 days were selected from groups for ultrastructure observation of hippocampus. Results No significant pathological changes were observed in nerve cells and capillary vessels in the hippocampus. Conclusion The results of the present paper indicate that pregnancy exposure to 1 800 MHz electromagnetic field,may not lead to abnormal ultrastructure changes in hippocampus of offspring rats
