Exposure device operators

To perform gamma radiography or operate an exposure device in Canada, the law requires you to be certified by the Canadian Nuclear Safety Commission (CNSC) as an exposure device operator (EDO) or be working under the direct supervision of a certified EDO.

As of January 1, 2017, the CNSC will consider a worker 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.

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.

More information on EDO certification:

  • EDO candidates – for individuals looking to become exposure device operators
  • Certified EDOs – for individuals seeking renewal of certification, seeking a certification card with an expiry date, or seeking to replace a damaged, lost or stolen certification card
  • Vocational training providers – for educational institutions and other organizations that design or offer vocational training programs for EDO candidates
  • On-the-job training providers – for educational institutions, gamma radiography licensees and other organizations that design or offer on-the-job training programs for EDO candidates
  • Licensees who employ certified EDOs
