Study type: Medical/biological study (experimental study)

An evaluation of the teratogenic potential of protracted exposure of pregnant rats to 2450-MHz microwave radiation: I. Morphologic analysis at term. med./bio.

Aim of study (acc. to author)

To study if chronic exposure of pregnant rats to 2450 MHz microwave irradiation at a power density level that does not result in a significant increase in maternal body temperature is teratogenic.

Main outcome of study (acc. to author)

No significant changes were found for the following parameters: maternal weight gain during pregnancy, maternal organ weights, term fetal weight, resorption rate, or abnormality rate. These data indicate that the protracted exposure of pregnant rats to 2450 MHz microwave irradiation at a power density level of 20 mW/cm² is not embryopathic.
