摘　　要：用PMM8053A场强分析仪测量了北京邮电大学信息网络中心的工频电场、磁场与高频电场。测试的工频电场强度为0.348～6.204V/m;工频磁通密度为0.059～0.412μT;高频电场强度为0.45～1.30V/m,都远小于国家标准与导则的限值水平。对比了一般室内电磁环境与一些电子电气设备的辐射水平,结果表明网络中心的辐射要大于一般居民室内的平均水平,但是远小于一些设备3cm处的辐射量值。The power frequency electric and magnetic fields and high frequency electric field in information network centre of Beijing University of Post and Telecommunications are measured by PMM8053A general-purpose field meter. The measured power frequency electric field strength is within the range from 0.348 V/m to 6.204 V/m; the power frequency flux density is within the range from 0.059 [aT to 0.412 ~T; the radio frequency electric field strength is within the range from the range from 0.45 V/m to 1.30 V/m; those ranges are much less than the limit values specified in relevant guidance and national standards. The radiation level in common indoor electromagnetic environment and the radiation levels of some electrical and electronic devices are compared, and comparison results show that the radiation level in network centre is higher than that in common habitable rooms, however the radiation level in network centre is much less than those of some devices measured at 3cm to the devices.
