Assessment of Brainwave Asymmetry and Hemisphere Dominance Due to RF Radiation

This paper discusses the characteristics of the electroencephalogram (EEG) signals due to the effects of mobile phone RF radiation exposure. The observation is focused on beta and alpha sub-bands. EEG recording was conducted on 66 healthy subjects for 3 sessions, pre, during and post RF radiation with 5 minutes exposure for each session. The subjects were divided into two groups refer to the side of exposure which is Left Exposure (LE) and Right Exposure (RE) group. Power Asymmetry Ratio (PAR) has been applied to determine the brainwave characteristics due to RF radiation. PAR value of the EEG signals in LE and RE group shows a decrement from pre to post RF radiation session. The correlation of PAR beta-alpha signals decrease when comparing between the sessions after exposed to the RF radiation (0.774 to 0.618 in LE and 0.579 to 0.295 in RE).
