在家庭中发现的工频磁场进行了调查，集中在背景场。其目的是调查目前的知识状况，并强调与流行病学研究有关的家庭领域的各个方面。在可能的情况下，强调不同国家之间的比较。考虑的场的方面是：背景场的来源;不同国家的平均背景场的强度;场的其他特征-谐波、椭圆率、方向、与静态场的关系-以及与家庭中的场的强度相关联的其他因素;不同来源的场对总的个人暴露的相对贡献，假设各种不同的确认-响应关系;场随时间变化的方式;最后，电场与磁场的不同之处，以及关于平均电场的稀疏信息。
The power-frequency magnetic fields found in homes are surveyed, concentrating on background fields. The aim is to survey the present state of knowledge and to highlight aspects of the fields in homes which are relevant to epidemiological studies. Wherever possible, emphasis is given to comparisons between different countries. Aspects of fields which are considered are: the sources of background fields; the strengths of average background fields in different countries; other features of the fields - harmonics, ellipticity, direction, relation to the static field - and other factors which are associated with the strength of the field in a home; the relative contribution of different sources of field to total personal exposure, assuming various exposure-response relationships; the way in which fields vary over time; and finally, the ways in which electric fields differ from magnetic fields, and the sparse information available on average electric fields.
