目的探讨高频电磁辐射对作业者神经系统的影响及脑电波变化特征。方法选择接触高频电磁辐射者166人为研究对象,无任何职业危害接触的60名健康成人为对照组。通过对他们神经系统及脑电图(EEG)的检查,分析不同的频率对高频电磁辐射作业者神经系统症状的影响及脑电波变化的特征,并与对照组比较。结果电磁辐射接触人员的神经系统症状及心悸的检出率明显高于对照组(P<0.01),其慢波(θ波和δ波)数量及EEG异常率与对照组比较,差异有统计学意义(P<0.01);EEGα波频率、波幅、百分率、功率及慢波(θ波和δ波)波幅三组之间差异无统计学意义(P>0.05)。结论高频电磁辐射可引起接触者EEG慢波增多,增加EEG异常率,并引发其神经系统症状。
Objective To investigate the effect of high frequency electromagnetic radiation on the operator's nervous system and the characteristics of brain wave changes. Methods Sixty-six people who were exposed to high-frequency electromagnetic radiation were selected as the research objects. Sixty healthy adults without any occupational hazards were selected as the control group. Through the examination of their nervous system and electroencephalogram (EEG), the influence of different frequencies on the nervous system symptoms of high frequency electromagnetic radiation workers and the characteristics of brain wave changes were analyzed and compared with those of the control group. Results The detection rate of nervous system symptoms and palpitations of people exposed to electromagnetic radiation was significantly higher than that of the control group (P <0.01). The number of slow wave (θ wave and δ wave) and EEG abnormal rate were significantly different from those of the control group (P <0.01). There was no significant difference between the three groups in EEGα wave frequency, amplitude, percentage, power and slow wave (θ wave and δ wave) (P> 0.05). Conclusion High-frequency electromagnetic radiation can cause slow wave of EEG in contact, increase the abnormal rate of EEG, and trigger its neurological symptoms.
