过去这20年间,科学家一直在调查诸如儿童白血病和成年人癌症等罕见疾病同其暴露于电磁场辐射之间可能存在的联系。这种暴露是因住在接近电流线路的地区或在电气设施周围工作而造成的。在斯堪的纳维亚国家、美国、加拿大和英国进行的一些大型研究得出结论说:因电磁场暴露而患癌症的危险很小。但是,他们所用方法中的某些缺点和他们的研究结果缺乏一致意见而使这场争论难以深入进行。 For the past 20 years, scientists have been investigating possible links between rare diseases such as childhood leukemia and adult cancer and exposure to electromagnetic radiation. This exposure is caused by living in areas near current lines or working around electrical facilities. Some large studies conducted in Scandinavia, the United States, Canada, and the United Kingdom have concluded that the risk of cancer due to exposure to electromagnetic fields is small. However, some of the shortcomings in the methods they used and the lack of consensus on their findings made this debate difficult to carry out.
