1 International Telecommunication Union Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda, 3-5 September 2003 ITU-T activities in EMF safety Greg Jones ITU Telecommunication Standardization Bureau

2 Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda September 2003 Context o 1996 – ITU-T SG5 became involved in the subject of human exposure to Electromagnetic Fields (EMF) o Increased use of radio systems has raised public awareness on EMF in the environment o Operators are now looking to control, measure and calculate EMF radiated to comply with the limits proposed by international bodies (such as the International Conference on Non- Ionizing Radiation Protection, ICNIRP) or national authorities

3 Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda September 2003 ITU-T Study Group 5 o Study Group 5 Protection against electromagnetic environment effects o Q 3/5 Radio-frequency environmental characterization and health effects related to mobile equipment and radio systems

4 Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda September 2003 EMF exposure standards o Basic restrictions The amount of electromagnetic energy absorbed by the human body o Reference levels Specify the limits in terms EMF

5 Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda September 2003 ITU-T Rec. K.52 o Guidance on complying with limits for human exposure to EMF Compliance with limits for mobile base stations and microwave links Based on simple prediction methods Includes mitigation techniques where limits are not met

6 Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda September 2003 Ongoing work o ITU-T SG5 is developing Recommendations for measurements and numerical prediction o Other areas that may be considered Additional installation guidelines Handset compliance

7 Seminar on Impact of Electromagnetic Field Emissions Kampala, Uganda September 2003 WHO EMF project o Gaps in knowledge Pulsed and modulated radio frequency fields o ITU-T SG5 collaboration o May result in revision of national or international exposure limits If this occurs, SG5 will evaluate the impact of the changes and revise any Recommendation affected
