SG 5 Mandate
Study Group 5 is responsible for :Studies relating to protection of telecommunication networks and equipment from interference and lightning;
Studies relating to electromagnetic compatibility (EMC), to safety and to health effects connected with electromagnetic fields produced by telecommunication installations and devices, including cellular phones ;
Studies on the existing copper network outside plant and related indoor installations.
Studies on ICT & Climate Change
Nairobi, Kenya, 26 – 27 July 2010 6
Meaning of the Mandate: Example
Study Electromagnetic Phenomena which can cause damages or disturbancesdamages or disturbances to telecommunication installation or injury to people injury to people (telecommunication personnel and service users) or health effect health effect to population

Nairobi, Kenya, 26 – 27 July 2010 9
Main tasks & Responsibility
Assignment of the exposure limits considered as safe for people - Medical bodies responsibility: WHO, ICNIRP, National medical authoritiesStandards 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 10
ITU-T Study Group 5Question 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
Nairobi, Kenya, 26 – 27 July 2010 11
History of Study on EMF in ITU-TNew 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 12
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

WTSA 08: Resolution 72"Measurement concerns related to human exposure to electromagnetic fields"
o Recognizing that some publications about EMF effects on health create doubt among the population, in particular in developing countries
o Resolves to invite ITU-T, in particular Study Group 5, to expand and accelerate its work and support
o Invites to contribute actively to the work of
Study Group 5 in providing relevant and timely information in order to assist to assist developing countriesdeveloping countries in providing information and addressing measurement concerns related to RF exposure
Nairobi, Kenya, 26 – 27 July 2010 15
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 16
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 17
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 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 workthere is no duplication of work
Nairobi, Kenya, 26 – 27 July 2010 18
Conclusion (2)
All the SG5 activities are reported in our web site: http://www.itu.int/ITU-/studygroups/com05/index.aspThe vast majority of all Recommendations are available in
electronic (PDF) form free of charge free of charge
