This study found no blood-brain barrier damage from cell phone-frequency radiation at levels exceeding typical device limits in young rats.

Plain English Summary

Summary written for general audiences

Researchers exposed young and developing rats to cell phone-frequency radiation (1439 MHz) for 90 minutes daily to see if it damaged the blood-brain barrier, which protects the brain from harmful substances. Even at high exposure levels (up to 6 W/kg), they found no changes in barrier function or protective proteins after 1-2 weeks of exposure. This suggests that this type of radiofrequency radiation may not compromise the brain's natural protective barrier in young animals.
