The Canadian Nuclear Safety Commission (CNSC) certifies exposure device operators. The Natural Resources Canada (NRCan) Non-Destructive Testing Certification Body (NDTCB) role is to serve as the qualifying body for the written examination for the CNSC's exposure device operator (EDO) certification.
An important step in becoming a certified exposure device operator (CEDO) is to register for and pass the EDO written examination. You can apply for and arrange this through the NRCan NDTCB. You will also need to provide CNSC with proof of appropriate vocational training. For information about training requirements, please contact CNSC.
How to apply and what is required for initial EDO written examination
Before applying to the NRCan NDTCB to write the EDO written examination, you must complete all required prerequisites as set out in the PCP-09 Certified Exposure Device Operator Personnel Certification Guide. You can download the guide from the CNSC website.

If you were approved to write your written EDO examination prior to the implementation of the electronic examination and you have not yet attempted the exam, you are required to submit to the NRCan NDTCB:
- A written request for electronic examination approval (via email)
- A scanned copy of your EDO Examination Admittance and Registration Form
After you have submitted your request and it has been processed, the NRCan NDTCB will issue electronic examination approval via email. If you have lost or misplaced your admittance form and cannot submit it with your request, fees may apply in order to obtain approval for the electronic examination. Please contact the NRCan NDTCB for more information on eligibility and registration for the electronic examination.
Please note: Email is the primary method of communication that the NRCan NDTCB uses to correspond with EDO applicants and candidates. The electronic written EDO examination is only available at approved EDO examination centres and other participating examination centres.
If your initial attempt to pass the EDO examination doesn’t succeed, you can attempt a re-examination. You should ensure there are at least 30 days between examination attempts. Candidates who are not successful after three attempts must repeat the vocational training program.
