1 Quito, Ecuador, 14 August 2013 Assessing EMF Levels Guidance and Recommendations Mike Wood EME Management Education & Compliance Telstra ITU Workshop on Human Exposure to Electromagnetic Fields (EMFs) (Quito, Ecuador, 14 August 2013)

2 Quito, Ecuador, 14 August Introduction This presentation covers Radio communications in the community Environmental radio spectrum plot Mobile network facilities Typical EMF assessments & methods ITU EMF recommendations Conclusions

3 Quito, Ecuador, 14 August Radio Communications Services

4 Quito, Ecuador, 14 August Radio Communication Powers

5 Quito, Ecuador, 14 August Radio Communication Spectrum Plot Typical radio signal levels in a community

6 Quito, Ecuador, 14 August Typical EMF Assessments Safety EMF compliance at sites OH&S for workers and public Environmental Radio signals in the community Educational & informative

7 Quito, Ecuador, 14 August Mobile Networks in the Community Example Town

8 Quito, Ecuador, 14 August Towers Masts or Poles

9 Quito, Ecuador, 14 August Rooftop Base Stations

10 Quito, Ecuador, 14 August Micro Cells

11 Quito, Ecuador, 14 August EMF Safety Assessment EMF Compliance Assessments on rooftops

12 Quito, Ecuador, 14 August EMF Safety Assessment - Public Assessment to the ICNIRP Guidelines

13 Quito, Ecuador, 14 August EMF Safety Assessment Assessment to the ICNIRP Guidelines

14 Quito, Ecuador, 14 August EMF Safety Assessment - microcells Micro cells operate at low power and typically have small compliance zones Assessment to the ICNIRP Guidelines

15 Quito, Ecuador, 14 August Example EMF Safety Assessment Assessment to the ICNIRP Guidelines Yellow – Public limit Red – Occupational limit Building Rooftop

16 Quito, Ecuador, 14 August Recommendations for EMF Assessments Safety EMF compliance at sites OH&S for workers and public Mitigation options to manage access Environmental Radio signals in the community Educational & informative

17 Quito, Ecuador, 14 August EMF Assessment Methods Calculations or Measurements? EMF Assessment method depends on site & environment Calculations - suitable in many cases, & have significant benefits - accurate, fast & cost effective. Measurements - required in very complex environments. Field Monitoring - Field monitoring is effective when working on towers for safety - Field surveys can provide public reassurance - Continuous monitoring – limited long term benefit where EMF levels are low and stable ITU Recommendations - guidance on both calculation and measurements

18 ITU Recommendations for EMF Assessments Quito, Ecuador, 14 August ITU-T K.91 guidance on how to assess and monitor human exposure to radio frequency (RF) electromagnetic fields (EMF) in areas with surrounding radio communication installations based on existing exposure and compliance standards – inc advantages and disadvantages of methods ITU-T K.83 guidance on how to make long-term measurements & monitoring of EMF in the selected areas that are under public concern, in order to show that EMFs are under control and under the limits. ITU-T K.70 defines techniques which may be used by telecommunication operators to evaluate the cumulative (total) exposure ratio in the vicinity of transmitting antennas and to identify the main source of radiation – includes EMF Estimator software ITU-T K.52 Guidance on complying with limits for human exposure to electromagnetic fields (telecommunications installations and handsets) ITU-T K.61 Guidance to measurement and numerical prediction of electromagnetic fields for compliance with human exposure limits for telecommunication installations

19 Quito, Ecuador, 14 August EMF Assessment Example - Australia Environmental EMF report is prepared for all base stations - follows Government calculation method & gives communities EMF information. Site ICNIRP Compliance Assessment is prepared for all base stations - follows accredited calculation and measurement process Government conducts site compliance audits & measurements at selected sites – ensures compliance, accurate information & public trust All site reports on internet database Public confidence has increased through transparency

20 Conclusions and Recommendations Quito, Ecuador, 14 August EMF Safety Important to assess EMF compliance at sites Important to establish OH&S procedures Environmental Educational & informative Radio signal levels are typically low & stable Calculation vs monitoring – a balance is needed Effective Public Communications
