GSM 900MHz signal affects a spectral power of alpha band in the resting human electroencephalogram
Abstract
The aim of this study was to examine the possible effect of exposure to radiofrequency electromagnetic field (RF EMF) GSM 900 MHz, on brain electrical activity. 26 healthy volunteers aged 18-35 years underwent two experimental sessions in which one session served as control (sham) and second one as exposure session. Subjects were exposed to mobile phone signals at intensity of 0.49 W/kg. In each session, waking EEG was recorded before, during and after an exposure period. These results suggest that GSM-EMFs of a mobile phone affect alpha band within spectral power of resting human EEG.
