The effects of prenatal exposure of rats to a 900 MHz electromagnetic field on the development of kidneys should be investigated.
Pregant rats were either exposed to the electromagnetic field or not exposed (n=3 each). The offspring from exposed rats was assigned to the exposure group (group 1, n=7) and the offspring from unexposed rats was assigned to the control group (group 2, n=7). After 60 days (remark EMF-Portal: 60 days after start or end of exposure or after birth? reference not clear), young animals were killed and investigated.

Mild congestion and renal tubule defects as well as a dilatation of Bowman's capsule and increased apoptosis were observed in the kidney tissues of rats in the exposure group compared to the control group. However, these changes were not statistically significant.
The only significant result was an increased potassium level in exposed rats compared to the control group.
The authors conclude that prenatal exposure of rats to a 900 MHz electromagnetic field might have an effect on the renal development.
