随着电力工业和科学技术的发展、电磁场对人体健康的影响,广为世人关注。我国第一条50Hz、27.5KV电力牵引铁路运输干线开通至今三十余年来,该电磁场对人体健康的影响,长期引起铁路各级领导的重视和职工、家属的关心和疑虑。为提供充分科学依据,成都铁路局特立题调查研究,于1990年至1991年首次进行大样本广泛深入调查研究。其结果,报告如下。 1.调查研究内容与方法 1.1 调查对象观察组(Ⅴ):宝成、成渝铁路干线上,在50Hz、27.5KV电力牵引供电网环境中作业的接触网检修
With the development of the power industry and science and technology, the electromagnetic field has a great impact on human health. The first 50Hz, 27.5KV electric traction railroad trunkline has been in operation for more than 30 years now. The impact of this electromagnetic field on human health has long aroused the attention of railway leaders at all levels and the concern and doubts of employees and their families. In order to provide sufficient scientific basis, Chengdu Railway Bureau special investigation and research, from 1990 to 1991 for the first time conducted a large sample extensive and thorough investigation and study. The result is as follows. 1.
