The Canadian Nuclear Safety Commission publishes REGDOC-2.2.3, Personnel Certification: Exposure Device Operators

News Release


March 1, 2017 Ottawa, ON

The Canadian Nuclear Safety Commission (CNSC) has published regulatory document REGDOC-2.2.3, Personnel Certification: Exposure Device Operators. This document does not introduce any new requirements and supersedes G-229, Certification of Exposure Device Operators, published in 2004.

REGDOC-2.2.3 provides a reference to the CNSC’s requirements and guidance for certification as an exposure device operator (EDO) and for renewal of EDO certification that can be found in the CSA Group’s Certified Exposure Device Operator Personnel Certification Guide and on the CNSC website.

An exposure device is a device that contains a sealed nuclear substance that is used in industrial radiography, to evaluate the internal structure and integrity of metals and other materials in pipelines, welds, castings and building structures. To operate such devices in Canada, a person must hold an EDO certificate from the CNSC or be working under the direct supervision of a certified EDO.

The CNSC regulates the use of nuclear energy and materials to protect the health, safety and security and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
