Rats exposed to cell phone radiation for up to 24 weeks showed no spatial memory problems, even at levels four times current safety limits.

Plain English Summary

Summary written for general audiences

French researchers exposed rats to 900 MHz cell phone radiation (the same frequency used by GSM phones) for either 8 or 24 weeks, then tested their spatial memory using a maze. The rats showed no memory problems compared to unexposed rats, even at radiation levels up to four times higher than current safety limits. This suggests that chronic cell phone radiation exposure may not impair spatial learning and memory functions in the brain.

Study Details

This study was carried out to investigate the behavioural effects of sub-chronic and chronic head-only exposure to 900 MHz GSM (Global System for Mobile communications) in male rats.

Rats were exposed for 45 minutes per day, at a brain-averaged specific absorption rate (SAR) = 1.5 W...

Performance of exposed rats (1.5 or 6 W Kg(-1)) was compared with that of sham, negative control an...

Sub-chronic and chronic head-only exposure of rats to GSM 900 MHz signal (45-minutes, SAR = 1.5 or 15-minutes, SAR = 6 W Kg(-1)) did not induce spatial memory deficit in the radial-arm maze
