This study found no brain cell damage from chronic cell phone radiation exposure at levels nearly four times higher than regulatory limits.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to cell phone radiation at 849 MHz and 1763 MHz frequencies for up to 12 months, delivering radiation directly to their heads at levels much higher than typical phone use. They found no evidence of brain cell death, abnormal cell growth, or other cellular changes in the exposed animals compared to unexposed controls.

Study Details

To study the effect of local exposure of mobile phone frequency irradiation to the mouse brain for 12 months

We established a carousel-type exposure chamber for 849 MHz or 1763 MHz of mobile phone RF radiation...

The brain tissues were obtained from 3 groups at 6 months and 12 months to examine the differences i...

From these data, we conclude that the chronic exposure to 849 MHz and 1763 MHz RF radiation at a 7.8 W/kg specific absorption rate (SAR) could not induce cellular alterations such as proliferation, death, and reactive gliosis.
