Two years of cell phone radiation exposure at levels four times higher than phone limits caused no detectable brain stress in mice.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to 900 MHz cell phone radiation for either 60 minutes or five days a week for two years, then examined their brains for signs of microglial activation - a cellular stress response that occurs when brain tissue is damaged. They found no evidence of brain cell stress or activation at either exposure duration, even at radiation levels much higher than typical cell phone use.

Study Details

To determine whether acute or long-term exposure of the brain to mobile telephone radiofrequency (RF) fields produces activation of microglia, which normally respond rapidly to any change in their microenvironment.

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

There was no increase in microglial Iba1 expression in brains short or long-term exposed to mobile t...

Acute (60 minutes) or longer duration (2 years) exposure of murine brains to mobile telephone RF fields did not produce any microglial activation detectable by Iba1 immunostaining.
