Structure of ITU-T SG5 ITU-T SG5 WP2/5 WP3/5 WP1/5 “Environment and climate change ” Q.14 Terminology WP1/5 Damage prevention and safety WP2/5 Electromagnetic fields: emission, immunity and human exposure WP3/5 ICT and climate change Study Group 5 has two working parties. WP1 studies protection of telecommunication systems and telecommunication personnel and users of telecommunication networks from lightning, induction from power lines. WP2 studies emission, immunity and security of telecommunication systems. EMC issues dealing with home networks are studied in Question 8. Also, it is necessary to include studies about protection from lightning and power line induction. The earthing system is essential for the countermeasure for the protection from lighting. These aspects are studied with relevant questions such as Q.4 and 6 and in WP1. 7 Questions 5 Questions 7 Questions Question 3/5 Human exposure to EMFs Nairobi, Kenya, 26 – 27 July 2010

ITU-T SG5 Question 3/5 "Human exposure to electromagnetic fields (EMFs) due to radio systems and mobile equipment" Rapporteur: Fryderyk Lewicki (Poland) Associate Rapporteur: Tariq Alamri (Saudi Arabia) Nairobi, Kenya, 26 – 27 July 2010

Main tasks & Responsibility Assignment of the exposure limits considered as safe for people - Medical bodies responsibility: WHO, ICNIRP, National medical authorities Standards for evaluation and measurement of exposure level - IEC, CENELEC, COST 281, National standardization committees Best practice, Implementation and guidance on telecommunication installations - ITU-T SG5 Nairobi, Kenya, 26 – 27 July 2010

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 Provide high level framework for managing the human exposure to EMFs (regulatory practices) emitted by the telecommunication equipment Provide guidelines for the assessment of human exposure based on the existing standards and commendations Activities specified in WTSA-08 Resolution 72 in order to assist developing countries in human exposure assessment. Nairobi, Kenya, 26 – 27 July 2010

History of Study on EMF in ITU-T New Question on EMF has started on 1996 and studying for 3 periods (12 years). Three Recommendations have established and revised since then : K.52: Guidance on complying with limits for human exposure to electromagnetic fields   K.61: Guidance on measurement and numerical prediction of electromagnetic fields for compliance with human exposure limits for telecommunication installations K.70: Mitigation techniques to limit human exposure to EMFs in the vicinity of radiocommunication stations Nairobi, Kenya, 26 – 27 July 2010

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 Nairobi, Kenya, 26 – 27 July 2010

ITU Recommendations related to human exposure E.M Radiation from a telecommunication installation E.M. Safety Limits Recommendation ITU-R BS.1698 ITU-T Recommendation K.52 ITU-T Recommendation K.61 ITU-T Recommendation K.70 Assessment of hazard and need for precautionary measures Mitigation Techniques to limit human exposure Nairobi, Kenya, 26 – 27 July 2010

WTSA 08: Resolution 72 "Measurement concerns related to human exposure to electromagnetic fields" Recognizing that some publications about EMF effects on health create doubt among the population, in particular in developing countries Resolves to invite ITU-T, in particular Study Group 5, to expand and accelerate its work and support Invites to contribute actively to the work of Study Group 5 in providing relevant and timely information in order to assist developing countries in providing information and addressing measurement concerns related to RF exposure Nairobi, Kenya, 26 – 27 July 2010

WTSA 08: Resolution 72 "Measurement concerns related to human exposure to electromagnetic fields"  Recommendation ITU-T K.guide will be written with Resolution 72 taken into account with big parts concerning EMF measurement with many examples with comparison measurement/calculation  Examples of action in accordance with Resolution 72 Technical session on EMF during SG5 meeting (May 2009) Workshop on EMF Nairobi, Kenya, 26 – 27 July 2010

ITU-T Recommendation K.guide "Guidance on how to manage human exposure to EMF’s" Guidance on how to handle the problem of the human exposure assessment in order to help the user to apply existing standards Procedures how to evaluate exposure by measurement by calculations Procedures how to show the compliance with exposure limits This Recommendation will be written in the possibly simple way and will be easy to understand Nairobi, Kenya, 26 – 27 July 2010

 Concerning human exposure to EMF: Conclusion (1)  Concerning human exposure to EMF: 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-T activity is complementary to the works carried out in other international standardization bodies involved in this subject - there is no duplication of work Nairobi, Kenya, 26 – 27 July 2010

Conclusion (2) Guide to the use of ITU-TSG5 publications 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 For a complete picture of SG 5 Publications: Guide to the use of ITU-TSG5 publications The document is aimed at telecommunications equipment designers and operators and will also be very helpful for users in developing countries Nairobi, Kenya, 26 – 27 July 2010
