| 摘 要： | [目的]调查宝山区居民住宅工频电磁场的接触水平。[方法]选取160户居民住宅，分别测定每户住宅各房间不同部位在室内所有电器打开、关闭的状态下的工频电磁场强度。[结果]家用电器关闭时，距高压线100m以内的住宅王频电磁场强度均明显高于100m以外的住宅；家用电器打开时，距高压线100m以内、以外住宅工频电场强度无明显差别，距高压线100m以内住宅工频磁感应强度明显高于100m以外的住宅。无论家用电器开、关，居民住宅内工额电磁场强度均高于上海市环境电磁辐射本底值，但远远低于国家环保标准限值。同一房间内，工频电场强度房间中央高于床头,工频磁感应强度没有差别。[结论]目前住宅内工频电磁场强度较室外本底值有所升高，但均明显低于国内外相关标准所确定的限值。
