摘要：
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 μT to 0.412 μT; 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 3 cm to the devices.
