A survey of 50 Hz electric and magnetic fields in the electric power industry has distinguished differences in exposure among the employees making it possible to compare health effects as a function of exposure. The workers that were most exposed to electric and magnetic fields were linemen and substation personnel who worked on facilities at operating voltages above 20 kV. On average, they were exposed to an electric field strength above 30 V/m for approximately 1.5 to 3 hours per day and to a magnetic flux density of around 1 to 2 microT. The least exposed group were linemen working in the 0.4 to 20 kV part of the network with exposure to a magnetic field of 0.10 microT. The electric field seldom exceeded 30 V/m.
一项对电力行业50赫兹电场和磁场的调查显示，员工之间的暴露情况存在显著差异，这使得能够根据暴露情况比较健康影响。接触电场和磁场最多的工人是线路工人和变电站工作人员，他们在运行电压高于20 kV的设施上工作。平均而言，他们每天暴露在30 V/m以上的电场强度下约1.5至3小时，磁通密度约为1至2微特斯拉。暴露最少的一组是在0.4至20 kV电网部分工作的线路工人，其磁场暴露为0.10微特斯拉。电场很少超过30 V/m。
