Exposure Device Operator (EDO) Certification

To perform industrial radiography or operate an exposure device in Canada, by law, you must hold a valid CNSC exposure device operator (EDO) certification.

Status Update:

  • A re-examination of EDO certification requirements is currently underway. In 2013, new EDO standards will be developed with respect to training, certification, renewal and recertification.

EDO Certification Process

The CNSC uses Certification of Exposure Device Operators (G-229) (PDF) to evaluate applications for certification as an EDO.

Once you are eligible for EDO certification, an application can be completed and submitted to the CNSC.  The following information is required to process the application:

  • The $1,000.00 processing fee, payable by credit card, or cheque or money order made payable to the Receiver General for Canada (see payment details - PDF);
  • A copy of the training certificate you received after successfully completing a 40-hour Exposure Device Operator vocational training program;

This letter should provide details of the Exposure Device Operator apprenticeship program that you completed, including the names of your supervisors and the topics that were covered during the program.  For more information on what should be submitted, see the sample Exposure Device Operator Apprenticeship Program letter;
  • A copy of the practical examination that you successfully completed, either with your employer or at a recognized testing centre. This practical examination should cover the topics listed under the eligibility requirements for EDO certification.

Processing time for an EDO certification

The CNSC typically processes an EDO application within 60 days of receipt of a completed application form, with payment of applicable fee, and required supporting documentation referenced.

If the CNSC requires additional information or does not accept your application, you will be notified within 10 working days of receiving your application.

To avoid delays:

  • Fill in the application form using clear readable print
  • Ensure that your application is complete and includes all required information
  • Verify that the contents of the CNSC document templates are included
  • Use the letterhead of the licensee and/or certifying authority
  • Ensure that applicant contact details are provided (e-mail address and phone number)
  • Provide a street address instead of a P.O. Box

To inquire about your EDO application 60 days after submission, please email the CNSC or call 1‑800‑668‑5284.

Alternative Training and Experience

To conduct industrial radiography in Canada, you must be certified through the CNSC, regardless of whether or not you are certified as an EDO in another country. Canada does not have agreements with other countries for recognition of EDO credentials.

The CNSC will assess each EDO application on a case-by-case basis, and may consider alternative types of education, training, and experience if they meet or exceed those specified in G-229. The CNSC will not issue a certification until it has reasonable assurance that the EDO candidate has the knowledge and skills required to safely operate an exposure device.

How to replace an EDO certificate

If you have damaged or lost your EDO certificate, have this request form (PDF) filled out by a licensed gamma radiography facility representative and send it to CNSC:

Mail:
Personnel Certification Division
Canadian Nuclear Safety Commission
280 Slater Street
P.O. Box 1046, Station B
Ottawa, ON

Email: edo-oae@cnsc-ccsn.gc.ca

There currently is no fee for a replacement certificate.

Maintaining EDO certification

The CNSC reserves the right to verify EDO operating experience and ensure that the required knowledge and skills to operate devices safely are maintained.  The CNSC can suspend or decertify if the EDO is not found to be operating in accordance with safety protocols and conditions, or if the EDO is causing undue risk to the public or the environment.

The CNSC publishes information about individuals who have lost their EDO certification.
