Extremely low frequency (60 Hz) electric and magnetic field levels were measured at three Canadian pulp and paper mills, using area point-in-time measurements. Most electric field levels were below the limit of detection of 1 V/m (92 of 132 measurements); the highest measured field was 47 V/m. Measured magnetic field strengths ranged from less than the limit of detection (0.125 mG, 2 of 132 measurements) to 706 mG, with a median of 1.6 mG. Magnetic field levels were higher in mills that consume more electric power, but worker exposures could not be predicted according to plant power consumption. Overall, electric and magnetic field levels in the three pulp and paper mills were similar to those experienced by the general population. However, maximum magnetic field intensities in some areas were as high as those experienced by electrical workers.
利用区域即时测量法，在加拿大的三家纸浆和造纸厂测量了极低频（60赫兹）电场和磁场水平。大多数电场水平低于1伏/米的检测限（132次测量中有92次）；测得的最高场强为47伏/米。测得的磁场强度范围从低于检测限（0.125毫高斯，132次测量中有2次）到706毫高斯，中位数为1.6毫高斯。耗电量较大的工厂中的磁场水平较高，但无法根据工厂耗电量预测工人的暴露情况。总体而言，这三家纸浆和造纸厂的电场和磁场水平与普通人群所经历的水平相似。然而，某些区域的最大磁场强度与电气工人所经历的强度一样高。
