Long-term intermittent cell phone radiation at typical usage levels showed no detectable brain tissue damage in this rat study.

Plain English Summary

Summary written for general audiences

Swedish researchers exposed rats to GSM-900 cell phone radiation once weekly for over a year at power levels similar to what humans experience during phone calls. When they examined the rats' brains afterward, they found no signs of damage including blood-brain barrier leakage, cell death, or aging-related changes. This suggests that intermittent cell phone radiation exposure at typical usage levels may not cause detectable brain tissue damage.

Study Details

We have investigated in a rat model the effects of repeated exposures under a long period to Global System for Mobile Communication-900 MHz (GSM-900) radiation.

Out of a total of 56 rats, 32 were exposed once weekly in a 2-h period, for totally 55 weeks, at dif...

In this study, no significant alteration of any these histopathological parameters was found, when c...
