Abstract
The present study was conducted to determine whether adolescents and or the elderly are more sensitive to mobile phone MP related bioeffects than young adults and to determine this for both 2nd generation 2G GSM and 3rd generation 3G W CDMA exposures To test this resting alpha activity 8 12 Hz band of the electroencephalogram was assessed because numerous studies have now reported it to be enhanced by MP exposure Forty one 13 15 year olds forty two 19 40 year olds and twenty 55 70 year olds were tested using a double blind crossover design where each participant received Sham 2G and 3G exposures separated by at least 4 days Alpha activity during exposure relative to baseline was recorded and compared between conditions Consistent with previous research the young adults alpha was greater in the 2G compared to Sham condition however no effect was seen in the adolescent or the elderly groups and no effect of 3G exposures was found in any group The results provide further support for an effect of 2G exposures on resting alpha activity in young adults but fail to support a similar enhancement in adolescents or the elderly or in any age group as a function of 3G exposure
