2. Toolbox presentation: Radiation Safety Part Two – Managing the risks

3. Only one aspect in protecting exploration workers from health hazards

4. Regulation of U mining in WA based on national and international standards

5. Mines Safety and Inspection Act and Regulations (MSIR) Free copies of the Act and Regulations may be downloaded from the WA State Law Publisher http://www.slp.wa.gov.au

6. MSIR Part 16 – Radiation Safety • Important notes • “Exploration” is considered to be mining under MSIR • Compliance with all regulations is required in exploration, including Part 16

7. Exemptions Dose limits Monitoring requirements Radiation management plan Radiation Safety Officer Defects Notifications Supervised and controlled areas Young and pregnant persons Designated employees Dose reduction Exposure control MSIR - Part 16 regulations cover

8. Respiratory protection Reporting Record keeping Approvals Import and removal of radioactive material Storage Stockpile control Waste disposal Using best technology Discharges Abandonment MSIR - Part 16 regulations cover continued 8

9. Exploration – radiation management plan (RMP) required by MSIR 16.7. Preparation of radiation management plan (1) Each responsible person at a mine must ensure that a plan for the safe management of radiation at the mine that complies with subregulation (2) is prepared — (a) in the case of an existing mine, as soon as is practicable after the commencement day; or (b) in any other case, before mining operations commence at the mine.

10. Company and site details Employee workgroup details Type of drilling Work and hygiene practices Radiation monitoring equipment Drilling and personnel monitoring Storage of radiation material Disposal of radioactive material Decontamination of equipment Recording of monitoring data Reporting to regulators Environmental considerations and site radiological clean up Training Transport of radioactive material Pre- and post-drilling background monitoring (including ground water sampling where practical) Exploration – RMP minimum requirements

11. NORM Guidelines - Preparation of RMP Exploration (NORM 2.1)

12. System of radiation protection

13. Other areas of control Risk assessment of hazards Radiation controls and plan put in place Monitoring of employees and environment Safe transport of radioactive material Correct storage of radioactive material Appointing a Radiation Safety Officer (RSO) Training of employees in radiation safety Emergency response in case of radiation spill or transport accident Auditing of radiation safety work procedures Reporting exposures and incidents to State Mining Engineer Regular review of radiation safety process
