Thirty minutes of 3G phone radiation showed no measurable impact on brain blood flow in this small study of nine men.

Plain English Summary

Summary written for general audiences

Japanese researchers used brain scans to study whether 30 minutes of exposure to 3G mobile phone radiation (W-CDMA at 1950 MHz) affects blood flow in the brain. Testing nine healthy men with PET scans before, during, and after phone exposure, they found no significant changes in regional brain blood flow compared to fake exposure. This suggests that 3G phone radiation at typical usage levels doesn't measurably alter blood circulation in the brain.

Study Details

This is the first study to investigate the effects of the third generation system on regional cerebral blood flow (rCBF) in humans.

We compared effects of the electromagnetic field (EMF) emitted from the Wideband Code Division Multi...

The subtraction analysis revealed no significant rCBF changes caused by the EMF conditions compared ...
