Summary of Estimated RF EME Levels around the ProposedRailCorp DTRS Site at Wollongong, NSW 2500Introduction: Date 16/02/2012 NSA Site No (052)This report summarises the estimated maximum cumulative radiofrequency (RF) electromagnetic energy (EME) levels atground level emitted from the proposed RailCorp DTRS Site at Wollongong, NSW 2500. Maximum EME levels are estimatedin 360° circular bands out to 500m from the base station. The procedures for making the estimates have been developed bythe Australian Radiation Protection And Nuclear Safety Agency (ARPANSA) 1 . These are documented in the ARPANSATechnical Report; “Radio Frequency EME Exposure Levels - Prediction Methodologies” which is available athttp://www.arpansa.gov.auEME Health StandardARPANSA, an Australian Government agency in the Health and Ageing portfolio has established a Radiation ProtectionStandard 2 specifying limits for continuous exposure of the general public to RF transmissions at frequencies used by mobilephone base stations. Further information can be gained from the ARPANSA web site.The Australian Communications and Media Authority (ACMA) 3 mandates exposure limits for continuous exposure of thegeneral public to RF EME from mobile phone base stations.

Theestimated levels have been calculated on the maximum capacity anticipated for this site. This estimation does not include possible radio signalattenuation due to buildings and the general environment. The actual EME levels will generally be significantly less than predicted due to pathlosses and the base station automatically minimising transmitter power to only serve established phone calls 4 . Where applicable, particularlocations of interest in the area surrounding the base station, including topographical variations, are assessed in Appendix A “ Other areas ofInterest” table on the last page.Summary – Proposed Radio SystemsRF EME levels have been estimated from the proposed antennas at Wollongong NSW 2500. The maximum cumulative EMElevel at 1.5 m above ground level is estimated to be 0.015 % of the ARPANSA public exposure limits.Environmental EME report (2007 ARPANSA Format) Page 1 of 3
