本研究旨在确定青少年和/或老年人是否比年轻人对移动的电话（MP）相关生物效应更敏感，并确定第二代（2G）GSM和第三代（3G）W-CDMA暴露的敏感性。为了测试这一点，评估了静息α活动（脑电图的8-12 Hz波段），因为许多研究现在已经报告它被MP暴露增强。41名13-15岁的青少年、42名19-40奥尔兹的青少年和20名55-70奥尔兹的青少年使用双盲交叉设计进行测试，其中每个参与者接受Sham、2G和3G暴露，间隔至少4天。记录暴露期间相对于基线的α活性，并在不同条件下进行比较。与之前的研究一致，年轻人在2G条件下的α值大于假手术条件下的α值，然而，在青少年或老年人组中没有观察到影响，并且在任何组中都没有发现3G暴露的影响。结果进一步支持2G暴露对年轻人静息α活性的影响，但未能支持青少年或老年人或任何年龄组作为3G暴露的函数的类似增强。Bioelectromagnetics 31：434-444，2010.

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.
