This study found no DNA damage from prenatal WiFi-frequency exposure, even at levels higher than typical human use.

Plain English Summary

Summary written for general audiences

Researchers exposed pregnant mice to 2.45 GHz radiofrequency radiation (the same frequency used in microwave ovens and WiFi) for 16 hours daily throughout pregnancy, then examined their offspring for DNA mutations in brain, liver, spleen, and reproductive organs. They found no increase in genetic damage compared to unexposed mice, even at radiation levels significantly higher than typical human exposure. This suggests that prenatal RF exposure at these levels does not cause detectable DNA mutations in developing mammals.

Study Details

A possible mutagenic effect of 2.45 GHz radiofrequency exposure was examined using lacZ-transgenic MutaTM mice.

Pregnant animals were exposed intermittently at a whole-body averaged specific absorption rate of 0....

Mutation frequencies at the lacZ gene in spleen, liver, brain, and testis were similar to those obse...

The data suggest that the level of radiofrequency exposure studied is not mutagenic when administered in utero in short repeated bursts.
