  2. Content • Introduction • Regulatory Expectations • Conclusion

  3. Introduction • Focus on regulatory expectations when conducting a radiography field inspection. • Just a perception of what we look for in Canada

  4. NSRD 30 – Obligations of Licensees • Appropriate and calibrated dosimetry • Calibrated radiation detection equipment • A safe and properly functioning device • Well maintained accessory equipment • Emergency Equipment • Signage and Barriers • Trained workers Please note – this is not a comprehensive list

  5. NSRD 31 – Obligations of Operators • Properly worn dosimetry • Use of a calibrated Survey Meter • Immediate availability of emergency equipment • DRD Readings and Pre-Op Checks • Placement of signs, barriers and persons • Locking of device while not in operation Please note – this is not a comprehensive list

  6. NSRD 31(6) – Emergency Situations • Source retrieval requires specialized training • Know your company’s response procedure • FOLLOW THIS PROCEDURE

  7. Field Documents • Valid CNSC Licence • Transport Document • TDG Certificate • Radiation Safety Manual • Device Operating Procedures • Emergency Response Procedures • CEDO Cards – highly recommended, but may soon be required.

  8. Required Equipment • Survey Meters – How many depends on what is in your company’s procedures • Dosimetry – TLD/OSLD, DRD, PAD • Emergency Equipment – Tunnel, Cutters, Tongs • Signage and Barriers – Condition and Placement

  9. Security • Overnight storage, unattended vehicle or return to the shop? • What security is required for your situation? • Know how to properly arm and disarm your system • Know what features your system has – GPS, FOB, etc • System condition – Bad contacts and loose wires

  10. CEDO Expectations (Knowledge) • Operator Obligations • Company Procedures • Signage and Area Control • Emergency Procedures • No-Go Gauge Checks • Teleflex Flex-test – we do expect to see this.

  11. Operations – Survey Meter Use • NSRD 31(1)(h) -after each attempt to move the sealed source assembly to the shielded position inside the exposure device, use a radiation survey meter to determine that the sealed source assembly is in the shielded position • Question: Does my surveymethod meet the intent of this regulation?

  12. Operations – The Device • Legible labels • Consignor ID • Source ID Tag • Field ID • Guide Tubes • Cranks • General Condition

  13. Operations – Signs and Barriers • Signs – posted at 25uSv/hr (2.5mR/hr) • Barriers – erected at 100uSv/hr (10mR/hr) Questions: Can I see the entire radiography area? Can I control the area? It is the Operator’s responsibility to ensure the area is properly controlled

  14. Operations - Transport • 4 Class-7 Placards • Transport Document within Driver’s Reach • Device securely stowed • PTNS 28(2) Exception: Certified device, one consignor only, 4 Class-7 placards • Words “Exclusive Use” can no longer be used.

  15. Operation – Dose to the Public • NSRD 30(6) and NSRD 31(1)(i): 0.1 mSv per week and 0.5 mSv per year. • CNSC Inspectors may ask for documented evidence that you are in compliance with these regulations. • What may raise our concerns? - Unexpected dose rates - Near-by occupied buildings - Reports from the Public

  16. Conclusion CNSC Expectations • Adherence to the Act and the Regulations • Adherence to your company’s policies and procedures • Safe and Responsible use of Nuclear Substances Field Inspections help the CNSC evaluate the adherence & effectiveness of a licensee's program.
