磁场对动物及人的生物学效应问题,国外巳有专著并发表过综述性文章。笔者等曾报道过国内有关作业工人接触磁场的强度并简述其防护措施。本文就稳态磁场(Stationary magnetic field,SMF)对接触工人行为功能的影响作一初步研究,并探索其安全接触强度。 对象与方法 一、调查对象 上海电化厂食盐电解车间金属阳极工段及石墨阳极工段操作工列为接触组,并选择年龄、性别组成类似的同厂非磁场及化学物接触工人作为对照组(见表1)。接触组两个工段90％的工人(33/37及23/26)的磁场接触工龄均为3年,其余为1—2年。
The biological effects of magnetic fields on animals and humans have been published monographs and published comprehensive articles abroad. I have reported on the domestic workers exposed to the strength of the magnetic field and briefed its protective measures. In this paper, a preliminary study on the effect of Stationary Magnetic Field (SMF) on the behavior of workers exposed to contact was conducted, and the safety contact strength was explored. Subjects and Methods 1. Survey respondents The metal anode section and the graphite anode section operator in the salt electrolysis plant of Shanghai Dianhua Chemical Plant were classified as the contact group and the same non-magnetic field and chemical contact workers of the same age and gender as the control group (see Table 1). 90% of workers (33/37 and 23/26) in both sections of the contact group have a magnetic field exposure of 3 years and the rest 1-2 years.
