Industrial radiography is a method of Non-Destructive Testing (NDT) where many types of simple or complex geometry manufactured components can be examined to verify the internal structure and integrity. Industrial radiography can be carried utilizing either X-rays (using an X-ray tube and generator) or Gamma Rays (using a radiography source such as Ir 192, Se 75, Yb 169 or Co 60 held in or projected from a Gamma projector). Both are forms of electromagnetic radiation.
Both methods have their own hazards and must only be carried out by fully trained personnel. Both methods use either industrial film or a digital imaging plate to capture an image which is either developed and viewed on a film viewer or displayed on a screen so as an inspector can review. Industrial Radiography can be carried out in a radiography bay or on-site such as a shipbuilding yard or oil refinery.
