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.



Exposure Parameters
Exposure 1: 2.45 GHz
Modulation type: CW
Exposure duration: 100 min/day for 6th to 15th day of gestation
  • SAR: 4.2 mW/g (at 28 mW/cm²)
