​ITU-T Study Group 5 – Activities on Human exposure to electromagnetic fields (EMFs) due to radio systems and mobile equipment

The World Telecommunication Standardization Assembly (WTSA-12) held in Dubai, 20-29 November 2012, approved Resolution 72: Measurement concerns related to human exposure to electromagnetic fields.
Within the Telecommunication Standardization Sector (ITU-T) of the International Telecommunication Union (ITU), ITU-T Study Group 5 (SG5) is the lead study group on ICT environmental aspects of electromagnetic phenomena and climate change.

SG5’s Working Party 2 studies EMF issues under Question 7/5: “Human exposure to electromagnetic fields (EMFs) due to radio systems and mobile equipment”. The resulting international standards (ITU-T Recommendations) provide high-level frameworks for the management of human exposure to EMFs emitted by telecommunication equipment (best-practice regulatory guidelines), and also offer guidelines for the assessment of human exposure based on existing ITU-T Recommendations and standards produced by other standards development organizations (SDOs).

To achieve these goals, Question 7/5 looks at measuring techniques, procedures and numerical models for evaluating the electromagnetic fields stemming from telecommunication systems and radio terminals.

A new EMF handbook or web-based ‘technical information paper’ including the option of an EMF information application is being developed.


​ITU-T K.52 provides guidance to compliance with safety limits for human exposure to electromagnetic fields (EMFs) as it relates to telecommunications installations,mobile handsets and other consumer devices emitting electro-magnetic radiation.
A new Appendix to ITU-T K.52 details the K52-calculator software that supports the application of the calculations presented in Appendix III, “Example of Equivalent Isotropically Radiated Power (EIRP) calculation”.


​EMF Estimator is a software application that implements the methodology described in ITU-T K.70 to calculate the cumulative radio frequency exposure levels in the vicinity of transmitting antennas. EMF Estimator also contains the library of the radiation patterns of transmitting antennas for a wide range of radio communication and broadcast services.
A typical application for EMF estimator would be the calculation of EMF levels in a local community from a cellular base station or community broadcast service. New features of the EMF Estimator software include options to import antenna patterns directly from manufacturers’ websites, as well as an option to present results of exposure level evaluations overlaid on a Google map.
