【摘要】 目的 研究高压输电线路的电磁辐射对人体健康的影响。方法 测试220kV和110kV市区常用的高压输电线路的电场和磁场的分布，在湖北的三峡地区、湖南、江西、四川、贵州、北京等地对居住在高压输电线路附近的1400多人进行了高压输电线路对人体健康的流行病学调查并对比检测了长期生活在高压输电线路附近的人员与远离输电线人群的脑电、心电和血液指标等部分生理指标。结果 高压输电线路的电磁场辐射强度随着距离的增大而迅速减少，其电场强度值大约从7000V/m变化到300V/m，其磁场强度值大约从0.1高斯变到0.01高斯左右。流行病学调查结果显示高压输电线路确实对人体构成了不同程度的影响，女性受影响相对较小, 男性较大。生理指标的测试结果提示生活在变电站附近的人群项指标都不同于远离变电站的人。结论 高压输电线路对人体健康产生了不同程度的影响。【关键词】 高压输电；电磁辐射；人体健康；流行病学调查

【Abstract】 Objective To study the influence of electromagnetic irradiation of high-voltage transmission on human body.Methods The distributions of electric and magnetic fields generated by high-voltage transmission lines with 110kV and 220kV were measured. Epidemiological investigations to 1400 inhabitants near high-voltage transmission line in Hubei, Hunan and Jiangxi, etc, were made. Some physiological parameters were measured among those people who have been living beside transformer substations for a long time and who live far away from high-voltage transmission systems.Results The intensity of electric filed of high-voltage transmission lines ranged from 7000V/m to 300V/m while magnetic filed from 0.1 Gauss to 0.01 Gauss. Results showed that the intensity of the electromagnetic field decreased quickly with increasing of distance from the transmission lines. The electromagnetic irradiation of the high-voltage transmission can really influence health of human body, especially for men, through investigation of epidemiology in Beijing, Sichuan and Hunan etc. Physiological parameters of those who were exposed to transformer substations for a long time were different from those of people who lived far away from transformer substations.Conclusion The electromagnetic irradiation of high-voltage transmission line might cause some influence in human body at different degree. ......
