Content • Introduction • Regulatory Expectations • Conclusion

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

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

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

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

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.

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

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

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.

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 survey method meet the intent of this regulation?

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

Operations – Signs and Barriers • Signs – posted at 25 u. Sv/hr (2. 5 m. R/hr) • Barriers – erected at 100 u. Sv/hr (10 m. R/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

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. • •

Operation – Dose to the Public • NSRD 30(6) and NSRD 31(1)(i): 0. 1 m. Sv per week and 0. 5 m. Sv 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

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.
