Radiography Level 1
TRAINING OBJECTIVES: This course is intended to provide a basic knowledge of industrial
radiography sufficient to enable the graduate to carry out radiographic inspection to
established procedures under the supervision of Level 2 or Level 3 personnel. Graduates
will be fully versed in the safe operation of both x- and gamma-radiography equipment, use
and care of radiation monitoring devices, and film processing.
APPLICABLE STANDARDS: This program meets the requirements of CAN/CGSB-48.9712, ISO 9712 and SNT-TC-1A.
This particular program also provides practical laboratory work with individual instruction
in x- and gamma-radiography, and film processing.
DEFINITION OF LEVEL 1 PERSONNEL (AS PER CGSB): Level 1 personnel are defined as
personnel who will carry out industrial radiography under the supervision of Level 2 or
Level 3 personnel and will not be responsible for the radiographic method or technique
to be used, nor for the assessment of radiographs.
