Itu t study group 5

ITU-T Study Group 5

Question 3/5 :Human exposure to electromagnetic fields (EMF) due to radio systems and mobile equipment

Guidance for the telecommunication sector

 Collaboration with other standardization bodies (IEC, CENELEC, WHO) in order to avoid duplication of work

Support to developing countries – Resolution 72


Itu t recommendations related to human exposure to e m fields

ITU-T Recommendations related to human exposure to E.M. fields

  • ITU-T Recommendations K.52 and K.61

  • Guidance on complying with safety limits for human exposure to e.m. fields from a telecommunication installation or mobile handset

  • Adopts a step-by-step approach to determine an exceedance zone (within which field exceeds reference limits)

  • Compliance achieved if exceedance zone is not accessible to personnel under normal conditions

  • ITU-T Recommendation K.70

  • Mitigation Techniques to limit human exposure to EM fields in the vicinity of radiocommunication stations

  • Software provided that implements methodology: EMF- estimator


Itu t recommendations related to human exposure to e m fields1

ITU-T Recommendations related to human exposure to E.M. fields

  • ITU-T Recommendations K.83: “Monitoring of EMF levels”

  • Gives guidance on how to make long-term measurement for monitoring of electromagnetic fields (EMF) in the selected areas that are under public concern in order to show that EMF are under control and under the limits.

  • The purpose of Recommendation K.83 is to provide for the general public clear and easily available data concerning electromagnetic field levels in the form of results of continuous measurement.

  • The balance between costs and

  • accuracy is very important


Itu t recommendation k 91

ITU-T Recommendation K.91

  • Guidance on how to handle the problem of the human exposure assessment in order to help the user to apply existing standards

    • Gives guidance on how to assess and monitor human exposure to (EMF) in the areas with surrounding radiocommunication installations based on existing exposure and compliance standards in the frequency range of 9 kHz to 300 GHz.

    • Oriented to the examination of the area accessible to people in the real environment of currently operated services with many different sources of RF EMF

    • Gives references to standards and recommendations related to EMF compliance of products.

  • A software is provided in order to help in the calculation of the uncertainty

  • Recommendation ITU-T K.91 developped with Resolution 72 taken into account

"Guidance for assessment, evaluation and monitoring of human exposure to radio frequency electromagnetic fields”


Itu t sg5 regional group for africa

ITU-T SG5 Regional Group for Africa

  • Created by SG5 (In accordance with Resolution 72), in May 2009

  • Objectives :

    • Encourage national authorities, operators and consumers from developing countries to work together and better contribute to ITU-T activities on the achievement of EMC in telecommunication installations as well as on EMF and human health

    • To enhance the collaboration on all activities related to “Climate change” in conformity with SG5 extended mandate

  • Contact: [email protected]


Conclusion

Conclusion

  • Presentation of the objectives of ITU-R and ITU-T with regard to studies on EMF

    • Activities relating to EMF exposure assessment for which Recommendations can be used to identify potentially hazardous situations and to comply with exposure limits

  • ITU-T SG5 takes part in standardization by preparing Recommendations, which give appropriate guidance for administrations and telecommunication operators and supports developing countries (Resolution 72)

  • ITU activity is complementary to the works carried out in other international standardization bodies involved in this subject - there is no duplication of work

  • Objectives of the SG5 Regional Group for Africa


Overview of itu t sg 5 activities

  • All the SG5 activities are reported in our web site: http://www.itu.int/ITU-/studygroups/com05/index.asp

    The vast majority of all Recommendations are available in electronic (PDF) form free of charge
