Mobile phone radiation at typical call levels showed no immediate effects on cognitive performance in healthy men during brief exposure periods.

Plain English Summary

Summary written for general audiences

Finnish researchers exposed 36 healthy men to mobile phone radiation at two different power levels (continuous and pulsed waves) while they performed cognitive tests, comparing left-brain versus right-brain exposure. They found no measurable effects on thinking abilities, reaction times, or other brain functions from either type of phone radiation. This suggests that typical mobile phone use doesn't impair basic cognitive performance in healthy adults.

Study Details

The possible effects of continuous wave (CW) and pulse modulated (PM) electromagnetic field (EMF) on human cognition was studied in 36 healthy male subjects.

They performed cognitive tasks while exposed to CW, PM, and sham EMF. The subjects performed the sam...

An additional control group of 16 healthy male volunteers performed the same tasks without any expos...
