Two years of high-level cell phone radiation exposure produced no detectable brain cell activation in mice, even at levels exceeding typical phone use.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to cell phone radiation (900 MHz) at high levels (4 W/kg SAR) for five days per week over two full years, then examined their brains for signs of astrocyte activation - a cellular response that indicates brain injury or stress. They found no detectable changes in these protective brain cells compared to unexposed mice, suggesting this level of radiofrequency exposure did not trigger measurable brain inflammation or damage.

Study Details

This study was designed to determine whether long-term (2 years) brain exposure to mobile telephone radiofrequency (RF) fields produces any astrocytic activation as these glia react to a wide range of neural perturbations by astrogliosis.

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

It was concluded that long-term (2 years) exposure of murine brains to mobile telephone RF fields did not produce any astrocytic reaction (astrogliosis) detectable by GFAP immunostaining.
