|Recommendation ITU-T K. 52 “Guidance on complying with limits for human exposure to electromagnetic
||This Recommendation aims to help with compliance of telecommunication installations and mobile handsets or other radiating devices used against one’s head with safety limits for human exposure to electromagnetic fields (EMFs). It presents general guidance, a calculation method, and an installation assessment procedure. The assessment procedure for telecommunication installations, based on safety limits provided by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), helps users determine the likelihood of installation compliance based on accessibility criteria, antenna properties and emitter power. The IEC Standard for the compliance measurement of mobile handsets is recommended.
|Recommendation ITU-T K.61 “Guidance on measurement and numerical prediction of electromagnetic fields for compliance with human exposure limits for telecommunication installations”
||Recommendation ITU-T K.61 helps telecommunication operators to verify compliance with exposure standards promulgated by local or national authorities. This Recommendation gives guidance on measurement methods that can be used to achieve a compliance assessment. It also provides guidance on the selection of numerical methods suitable for exposure prediction in various situations.
|Recommendation ITU-T K.62 “System level radiated emissions compliance using mathematical modelling”
||This Recommendation supports telecommunication operators in demonstrating the compliance of the radiated emissions generated by telecommunication systems. Telecommunication operators typically construct their systems from many items of equipment that are each engineered to individually meet EMC requirements, including radiated emissions. This means that a system will typically contain a number of emissions sources (i.e., separate equipment items) at a number of common frequencies. This is true if the system contains many items of the same equipment or many items of different equipment. The system as a whole will generally be expected to comply with a radiated emissions limit. This may be the same or different to the limit applicable to the individual constituent equipment. For each common emission frequency, the presence of many individual sources within the system means that the system emission level may be higher than that of the individual equipment. This Recommendation presents a method that allows the radiated emissions to be assessed without performing practical measurement. The method presented is particularly suited to the analysis of systems that are physically very large, for which practical testing is both prohibitively expensive and practically difficult to perform.
|Recommendation ITU-T K.70 “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.).
|Recommendation ITU-T K.83 “Monitoring of electromagnetic field levels”
||Recommendation ITU-T K.83 gives guidance on how to make long-term measurements for the monitoring of electromagnetic fields (EMF) in the selected areas that are under public concern, in order to show that EMFs are under control and under the limits. The purpose of this Recommendation is to provide for the general public clear and easily available data concerning electromagnetic field levels in the form of results of continuous measurement.
|Recommendation ITU-T K.90 “Evaluation techniques and working procedures for compliance with exposure limits of network operator personnel to power-frequency electromagnetic fields”
||Recommendation ITU-T K.90 provides evaluation techniques and guidelines for compliance with safety limits for human exposure to electromagnetic fields (EMFs) of telecommunication network personnel (e.g., outside plant craft) at power frequencies (DC, 50 Hz and 60 Hz). This Recommendation does not set safety limits; it seeks to provide techniques and procedures for determining the need for any precautions at the work site. This Recommendation includes an electronic attachment containing the EMFACDC program.
