Mobile phones are indispensable for daily life, and the adverse effects of the electromagnetic field (EMF) emitted by mobile phones have been a great concern. We studied the effects of long-term evolution (LTE) -like EMF for 30 min on an awake electroencephalogram (EEG). Thirty-eight healthy volunteers, aged 20 to 36 years old, participated in this study. The maximum local SAR (specific absorption rate) averaged over 10-g mass was 2.0 W/kg. The EEG was recorded before and after real or sham exposures. The effects of exposure conditions (real or sham) and the recording time (before, during, and after exposure) on each EEG power spectrum of θ, α, and β frequency ranges were analyzed. The θ and α band waves were enhanced after both exposure conditions. These results may be explained by the participants' drowsiness during the EEG recording in both exposures. We conclude that an LTE-like exposure for 30 min in this study showed no detectable harmful effects on awake EEGs in healthy humans.

长期进化的电磁场对健康人清醒脑电图的影响

手机是日常生活不可或缺的一部分，手机发出的电磁场（EMF）的不良影响一直备受关注。我们研究了 30 分钟的长期进化 (LTE) 样 EMF 对清醒脑电图 (EEG) 的影响。38 名年龄在 20 至 36 岁之间的健康志愿者参与了这项研究。平均超过 10 克质量的最大局部 SAR（比吸收率）为 2.0 W/kg。在真实或假暴露之前和之后记录 EEG。分析了暴露条件（真实或假）和记录时间（暴露前、暴露期间和暴露后）对 θ、α 和 β 频率范围的每个 EEG 功率谱的影响。θ 和 α 波段波在两种曝光条件下都得到增强。这些结果可以由参与者的解释 两种曝光的 EEG 记录期间的困倦。我们得出的结论是，在本研究中，类似 LTE 的暴露 30 分钟对健康人的清醒脑电图没有可检测到的有害影响。
