Radiography Testing

Radiography Testing (RT) Level I

Training Course Objective

To provide a basic knowledge of RT to enable a participant to carry out tests according to an established procedure under the supervision of a Level II or Level III personnel. The course is especially designed to provide sound theoretical knowledge and practical skill for RT required for a Level I technician.

RT Level I Responsibilities

To carry out operations as per written procedure/instruction from Level II personnel. A Level I technician shall be able to set up and carry out tests as per established and approved RT procedures, classify and report the results, and follow safety norms. They shall not be responsible for the choice of test technique nor for assessment of the test results.

RT Level I Course Outline

• Nuclear physics and interaction of radiation with matter
• Shielding, radiation detectors, and biological effects
• Radiation protection, basic rules, and techniques
• Sources of radiation and their characteristics
• Film radiography and film processing
• Inspection techniques and procedures
• Sensitivity and definition, I.Q.Is, and other accessories
• Types of discontinuities

RT Level I Practical Training

Radiography of castings and welds using X-ray and gamma ray.

Radiography Testing (RT) Level II

Training Course Objective

The course is intended to provide thorough grounding in the principles of Radiography Testing (RT) and fundamentals of material and process, such that the trainee is able to identify the suitability of RT for the material and inspection technique, develop techniques and procedures that can be followed by a Level I operator, analyse the test result and document the same, be familiar with codes, standards, and specifications for RT to evaluate results of the tests, and be conversant with all statutory and safety norms of the authorities under jurisdiction.

RT Level II Responsibilities

A certified RT Level II personnel is qualified to:

• Select proper test technique, equipment, films, IQI, and other test parameters
• Set up the equipment and perform testing
• Manually process film for high contrast and resolution and interpret the results as per applicable standards
• Have knowledge of the scope and limitations of RT
• Be familiar with production processes of the test material and knowledge of the type and location of expected defects
• Describe the operational steps in the radiography test method and understand the importance of each step
• Develop RT technique for testing a particular job
• Prepare test reports for: (i) Accept, (ii) Reject, (iii) Rework
• Prepare written instructions for Level I
• Guide and check test results of Level I operators
• Be responsible for the care and maintenance of the NDT/RT equipment

RT Level II Course Outline

• Review of Level I course
• Non-conventional radiography techniques
• Codes, standards, and procedures
• Acceptance standards
• Manufacturing processes and discontinuities
• Interpretation of radiographs

RT Level II Practical Training

Same as Level I, plus interpretation and evaluation of radiographs, recording of test results, and preparation of test reports.
