中文摘要：

目的 分析文献报道的工频电场检测数据,对检测现状提出看法及建议.方法 检索历年来专业文献中的工频电场检测数据,得到306篇文献与193个有效检测数据.对检测数据进行Mann-Whitney和Wilcoxon W检验.结果 以接触限值的1/4（1.25 kV/m）、1/2（2.5 kV/m）和接触限值（5 kV/m）对数据进行划分,发现非电力设施和电力设施的检测数据的结构差异有统计学意义（P＜0.05）.结论 作为职业有害因素,工频电场辐射的暴露虽广泛,但除去特定的高电压电力相关设施,在工作中工频电场的检测数据却远小于接触限值,其危害性较小.目前存在过度检测的现象.

英文摘要：

Objective To analyze the literature on power frequency electric field testing data and to propose views and suggestions for current testing.Methods The literature on power frequency electric field testing data published in the previous years was searched to identify 306 articles involving 193 valid testing data.Mann-Whitney test and Wilcoxon W test were used for analyzing the testing data.Results The classification of data was carried out according to one quarter of occupational exposure limit （1.25 kV/m）,one half of the exposure limit （2.5 kV/m）,and the exposure limit （5 kV/m）.The structure of testing data showed a significant difference between the non-power facility group and the power facility group （P〈0.05）.Conclusion As occupational hazard factors,the radiation exposure from power frequency electric field is extensive.However,the power frequency electric field testing data in actual workplaces except high-voltage power facilities are far less than the occupational exposure limit with little harmfulness.There is a phenomenon of excessive testing at present.
