In utero exposure to low-level microwaves does not affect rat foetal development.
Forty pregnant Sprague-Dawley rats were used in a study to determine low-level microwave effects on foetal development. Animals were continuously exposed to 2450 MHz radiation from day 2 to day 18 of gestation, at a specific absorption rate of 0.4 W/kg. Foetuses were removed, weighed and measured. They were then either fixed in Bouin's fluid, sectioned at 6 microns, stained with hematoxylin and eosin and examined by light microscopy, or cleared and stained with alizarin red. No significant difference was noted with respect to foetal weight, length, resorption rate or abnormality rate.
