Certified exposure device operators

Exposure device operators (EDOs) certified by the Canadian Nuclear Safety Commission (CNSC) are required to renew their certification every five years to continue working as certified EDOs. Renewal of EDO certification is not automatic.

The CNSC reserves the right to verify that certified EDOs maintain the required knowledge and skills to operate exposure devices safely and securely. The CNSC may take regulatory action – up to decertification – if a certified EDO is found to be operating contrary to safety protocols and conditions, or if a certified EDO is causing undue risk to the public or the environment.

As of January 1, 2017, the CNSC will consider a worker to be qualified to operate an exposure device only if they have a valid EDO certification card (that is, a card issued on or after February 1, 2013 that has not expired). As a result, any EDO whose certification card does not have an expiry date or whose certification card has expired will not be considered qualified to work as a certified EDO.

Valid EDO certification cards show the expiry date of the EDO certification:

Expectations for renewal of an EDO certification

The CSA Group's document CSA PCP-09, Certified Exposure Device Operator Personnel Certification Guide is the official guide for CNSC EDO certification and renewal of certification.

Certified EDOs are expected to maintain their knowledge and skills to safely operate an exposure device by completing an EDO practical examination, completing EDO-related continuing education and working continuously as a certified EDO. To renew your EDO certification, you are expected to have:

  • successfully completed an EDO practical examination within the past 12 months that was administered by an authorized examiner (see a sample EDO practical examination from CSA PCP-09)
  • successfully completed at least 40 hours of continuing education over the last five-year period
    • As a certified EDO, you are responsible for maintaining a log and retaining proof of the completion of your EDO-related continuing education activities (see a CNSC sample of a certified EDO continuing education log [FORM-EDO-R-CE]). You may be asked to submit this information to the CNSC.
  • continuously worked as a certified EDO:
    • at least 320 hours of work as a certified EDO in the previous two years and no single period of non-work as a certified EDO that exceeds 12 months in the previous three years
      OR
    • continuous work as a radiation safety officer, supervisor of certified EDOs, trainer of certified EDOs or an emergency responder over the previous three years, with any single period of work not related to certified EDOs not to exceed six months
  • As a certified EDO, you are responsible for maintaining a log of your EDO-related work experience (see a CNSC sample of a certified EDO work log [FORM-EDO-R-CW]). You may be asked to submit your EDO work log to the CNSC.

Certified EDOs who cannot meet these expectations for renewal of certification may have to complete the EDO written examination. For more information, visit the NRCan National Non-Destructive Testing (NDT) Certification Body website.

How to apply for renewal of your EDO certification

The CNSC recently updated the application forms for renewal of an EDO certification.

You must submit your application for renewal of your EDO certification within 6 months but no later than 60 days before the expiry date of your certification. If your application is received by the CNSC less than 60 days before the expiry date of your certification, your certification may expire before the CNSC completes its assessment.

Submit the following information to apply for renewal of your EDO certification:

  • a completed CNSC application form for the renewal of an EDO certification (FORM-EDO-R)
  • a copy of the EDO practical examination that you successfully completed within the past 12 months and that was administered by an authorized examiner (see a sample EDO practical examination from CSA PCP-09)
  • if you are currently employed as a certified EDO, a completed CNSC EDO employer attestation form (FORM-EDO-R-A)
  • if you completed the EDO written examination as an alternative to working continuously in gamma radiography, a copy of a letter from NRCan stating that you successfully completed the EDO written examination

There is currently no fee for renewal of an EDO certification.

No expiry date on your certification card?

If your certification card does not have an expiry date, submit an application for renewal of an EDO certification to the CNSC by following the steps outlined above.

Is your certification card damaged, lost or stolen?

If your EDO certification card is damaged, lost or stolen, complete the CNSC application form for a replacement EDO certification card (FORM-EDO-DLS). There is currently no fee for a replacement certification card.
