Plain English Summary
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...
