Fetal mouse brains showed no stress response to cell phone radiation at twice current safety limits throughout pregnancy.

Plain English Summary

Summary written for general audiences

Researchers exposed pregnant mice to cell phone radiation (900 MHz) for one hour daily throughout pregnancy to see if it caused stress in developing fetal brains. They measured heat shock proteins, which are biological markers that cells produce when under stress. The study found no evidence that the radiation caused stress responses in the fetal brain tissue, suggesting no detectable harm at the exposure levels tested.

Study Details

To determine whether whole of gestation exposure of fetal mouse brain to mobile telephone radiofrequency fields produces a stress response detectable by induction of heat shock proteins (HSPs).

Using a purpose-designed exposure system at 900 MHz, pregnant mice were given a single, far-field, w...

There was no induction of HSP32 or 70 in any brains, while HSP25 expression was limited to two brain...

Whole of gestation exposure of fetal mouse brains to mobile phone radiofrequency fields did not produce any stress response using HSPs as an immunohistochemical marker.
