Radiography Level 1 & 2
Radiography Level 1

PREREQUISITE: Registrants must satisfy all prerequisites that pertain to this training course.

TRAINING OBJECTIVES:  This course provides the basic knowledge of industrial radiography to enable the graduate to conduct radiographic inspection to established procedures under the supervision of Level 2 or Level 3 personnel. The course includes hands-on experience in the use of x-ray radiography and darkroom techniques.

APPLICABLE STANDARDS: This course meets the training syllabus requirements of CAN/CGSB-48.9712, ISO 9712 and SNT-TC-1A.

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.
