ITU-T K.91 (11/2019)

无线电频率电磁场对人体辐射的评定、评估和监测指导意见

存在着多种可能的暴露评估方法且每种各有利弊。ITU-T K.91建议书为在周围有无线电通信设施的区域，如何在现有9 kHz至300 GHz频率范围内的暴露和合规标准的基础上评估和监控人体暴露于射频（RF）电磁场（EMF）提供了导则。这包括评估暴露及如何根据现有的标准显示是否满足暴露限值的程序。

ITU-T K.91建议书旨在研究人们可以进入的、当前正在运营业务的真实环境中有各种不同射频电磁场源的地区，但也给出了与产品EMF合规有关的标准和建议书。ITU-T K.91建议书包括含有不确定性计算器和Watt 保护模块的电子附件。
