本文500kV高频场强进行了现场测试,结果站内场强最高达78.6dB,线路场强最高达67.7dB。并对在此环境中工作的人员进行了临床、电生理、生化、激素、免疫等42项指标测试;结果:出现不同程度的疲劳症状者占89%(47/53)。证实了高压场强所致疲劳的现象确实存在。并把这种现象称为高频场强对人体的生物学负效应。生化与免疫学测试中K~+、Ca~(++)、Mg~(++)、血糖增高与IgG、IgA、IgM及HP抗体有统计学意义的降低可能与场强负效应有关。强调机体免疫水平降低可能是高频场强所致疲劳的重要原因。提出提高免疫功能,增强机体抗场强辐射能力,调节免疫活性细胞的凋亡周期,延缓细胞凋亡的时间,将成为抗疲劳的重要手段和研究方向。
In this paper, a field test of 500kV high frequency field was carried out. As a result, the maximum field strength within the station reached 78.6dB and the maximum field strength reached 67.7dB. And 42 staffs in this environment were tested in clinical, electrophysiology, biochemistry, hormones and immunity. Results: 89% (47/53) patients showed different degrees of fatigue symptoms. Confirmed the phenomenon of fatigue caused by high-pressure field does exist. And this phenomenon is called the biological high frequency field negative effect on the human body. Biochemical and immunological tests K ~ +, Ca ~ (++), Mg ~ (++), elevated blood glucose and IgG, IgA, IgM and HP antibody statistically significant reduction may be negative field effects. Emphasis on the body to reduce the level of immunity may be caused by high-frequency field fatigue caused by an important reason. Put forward to improve immune function, enhance the body against field radiation ability, regulate the immune apoptotic cell cycle, delay cell apoptosis time, will become an important means of anti-fatigue and research direction.
