The NRCan NDTCB has implemented a user fees update to existing fees; this update will take effect July 1st, 2017. Additional new services and fees will be introduced at a later date. Application and fee submissions to the NRCan NDTCB that are postmarked, emailed or faxed after June 30th, 2017 are subject to the new fee schedule.
The NRCan NDTCB has transitioned to a new certification photo ID card design and format as of April 26, 2017. All cards issued after May 12, 2017 will utilize the new design and format. Both the new and old card versions are valid unless the card has expired.
To perform gamma radiography or operate an exposure device in Canada, by law you must either:
- Hold a valid exposure device operator (EDO) certificate from the Canadian Nuclear Safety Commission (CNSC), or
- Be working under the direct supervision of a certified EDO (CEDO)
Our role in EDO certification
The Canadian Nuclear Safety Commission (CNSC) is responsible for certifying exposure device operators. The Natural Resources Canada Non-Destructive Testing Certification Body (NDTCB) serves as the qualifying body for CNSC's written examination for EDO certification.
If you are successful on the EDO written examination, NDTCB will issue you a photo identification card. This card is used in conjunction with a valid CEDO card issued by CNSC.
For questions about EDO certification beyond the written examination stage, please contact CNSC.
