| 在无线电通信电台附近限制人体暴露于电磁场（EMF）方面的缓解技术 |
ITU-T K.70建议书规定了可被电信运营商用于评估发射天线附近累积（总）暴露比并确定主要辐射源的方法。它提供了可降低辐射水平，以便遵守暴露限值的缓解方法的导则。它也提供了（现场）环境（绝大多数情况下，同时暴露于许多不同来源的多个频率）所需程序的导则。辐射源可能属于多个运营商且可能代表着不同的无线电通信业务（如蜂窝系统、集群系统、广播、无线电中继、无线接入等）。 |

| Observation: | This Recommendation contains a software EMF-estimator that implements the methodology described in ITU-T K.70, and gives the possibility to calculate the cumulative exposure for the reference levels. It also contains the library of the radiation patterns of transmitting antennas for a wide range of radiocommunication and broadcast services. The EMF-estimator is not appropriate for the equipment certification in order to put it on the market.
A new version v2.0.0 of EMF estimator is available in ITU-T K.70 (2007) Amend.2 (2011-05). |
