Alpha band of resting electroencephalogram perturbed by radio frequency exposure

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. 30 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. Statistical analysis is ongoing for alpha, theta and beta waves. Data so far analyzed suggest a trend towards the difference in the alpha band between sham and exposed periods. Completed data will be presented at the meeting.
