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.
New 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 documentCSA PCP-09, Certified Exposure Device Operator Personnel Certification Guide is the official guide for CNSC EDO certification and renewal of certification.
