This study found no immediate brain wave changes during single mobile phone exposures, but doesn't address long-term health effects.

Plain English Summary

Summary written for general audiences

Researchers exposed 15 healthy adults to electromagnetic fields from both GSM (2G) and UMTS (3G) mobile phones while measuring their brain activity with EEG and asking about their well-being. They found no significant changes in brain wave patterns or reported symptoms compared to fake (sham) exposure. The study suggests that typical mobile phone radiation levels don't produce detectable immediate effects on brain activity in healthy users.

Study Details

The aim of this study is to investigate Effects of weak mobile Phone-Electromagnetic fields (GSM, UMTS) on well-being and resting EEG.

we tested the effects of both types of EMF, 1950 MHz UMTS (SAR 0.1 and 1 W/kg) and pulsed 900 MHz GS...

Neither the UMTS- nor the GSM-EMF produced any significant changes in the measured parameters compar...

The results do not give any evidence for a deleterious effect of the EMF on normal healthy mobile phone users.

Quick Questions About This Study

A 2008 study found that 1950 MHz UMTS (3G) radiation produced no significant changes in brain wave patterns measured by EEG. Researchers exposed 15 healthy adults to both UMTS and GSM signals, finding no detectable differences in brain activity compared to fake exposure sessions.
Research shows 3G phone signals don't cause immediate symptoms in healthy users. A controlled study exposing adults to both 3G UMTS and 2G GSM radiation found no significant changes in reported well-being or physical symptoms compared to sham exposure sessions.
EEG studies provide no evidence that mobile phone EMF harms brain function in healthy users. A 2008 study using precise brain wave measurements found neither GSM nor UMTS electromagnetic fields produced detectable changes in normal brain activity patterns.
GSM and UMTS phone signals don't affect the brain differently according to EEG research. A study comparing both 2G GSM and 3G UMTS exposure found neither technology produced significant changes in brain wave patterns or well-being in healthy adults.
The Kleinlogel 2008 study revealed no evidence of harmful effects from mobile phone radiation on healthy users. Using EEG monitoring and symptom tracking, researchers found neither GSM nor UMTS electromagnetic fields caused detectable changes in brain activity or well-being.
