ITU-T K.70 (06/2007)

عربي | 中文 | English | Español | Français | Русский
Mitigation techniques to limit human exposure to EMFs in the vicinity of radiocommunication stations
ITU-T Recommendation K.70 defines techniques which may be used by telecommunication operators to evaluate the cumulative (total) exposure ratio in the vicinity of transmitting antennas and to identify the main source of radiation. It offers guidance on mitigation methods which allow reduction of radiation level in order to comply with exposure limits. It also provides guidance on procedures necessary in the environment (on site) in which, in most cases, there is a simultaneous exposure to multiple frequencies from many different sources. Radiating sources may belong to many operators and may represent different radiocommunication services (e.g., cellular systems, trunking systems, broadcasting, radio relays, wireless access, etc.).

Provisional, K.pred
Approval process:AAP
Status: Superseded
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).
