电源电磁场是指电力输配电网络在其供电和用户在用电过程中,因电源的线路布设均暴露在外,从而在人们的日常生活环境中形成了无处不在的电磁场。这种电磁场的存在,长期以来被认为是无害的,甚至能够被传统的理论所证明。近十几年来,随着生活水准和质量的不断提高,以及实际的观察和初步的研究,这个结论似也受到了挑战。电源电磁场对人体健康是否有影响,可能会产生哪些影响,是目前职业病和流行病研究的前沿之一。 瑞典从事这方面的研究经历了15年的过 Power electromagnetic field refers to the power transmission and distribution network in its power supply and the user in the process of power supply, due to the layout of the power lines are exposed, thus forming a ubiquitous electromagnetic field in people’s daily living environment. The existence of such an electromagnetic field has long been considered innocuous and can even be proved by traditional theories. In the past decade or so, with the continuous improvement of living standards and quality, as well as practical observations and preliminary studies, this conclusion seems to be challenged. It is one of the frontiers of current occupational diseases and epidemiological studies about the potential impact that power electromagnetic fields have on human health. Sweden has been engaged in research in this area for 15 years
