Observations of rat fetuses after irradiation with 2450-MHz (CW) microwaves. med./bio.

Published in: J Microw Power 1981; 16 (1): 9-13

Aim of study (acc. to author)

This in vivo study was conducted to explore possible effects of microwave exposure during pregnancy in rat fetuses.

Background/further details

A total of 70 female rats (90-day-old) were microwave irradiated and 67 animals sham exposed. On the 21st day of pregnancy, each female was killed and their fetuses examined.
