RT Result


Radiographic Testing (RT), or industrial radiography, is a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials.


  • The course is suitable for:
  • • Radiographers, inspectors, engineers and surveyors who wish to interpret radiographs but do not have a good understanding of the principles of radiography.

    • Course Content:
    • • This course designed for personnel responsible for judging the quality of radiograph and reaching informed decisions regarding the identity and extent of the defects revealed. Training in radiographic interpretation provides essential knowledge on radiographic theory and practice to enable interpreters to judge radiographic quality and practical interpretation of welds and castings respectively.
    • • Principles of X- and gamma-radiography; equipment; safety; selection of films and screens; exposure; processing; characteristics of the image; choice of technique; relevant standards; sensitivity, factors affecting the quality of radiographs.
    • • The course ends with the certificate examination.
    • • Training in accordance with the requirements of BS EN ISO 9712.

    • Certification/Awarding Body:
    • • CSWIP

      • Course Objectives:
      • • To explain the basic theory of radiography
      • • To state origin of defects
      • • To state basic radiation safety principles
      • • To explain principles relating to selection of films, energy levels and techniques
      • • To evaluate radiographic sensitivity
      • • To recognise and differentiate between film artefacts and defect indicators
      • • To interpret radiographs
      • • To meet the syllabus of CSWIP Level 2
