NDT - Conventional Radiography
The Objective
Radiography is a Non-Destructive Examination method that uses X-ray and Gamma-ray for detecting internal imperfections, for measuring wall-thickness and for detection of corrosion.
The Solution
Conventional Radiography involves the process where radioactive rays are directed at the object to be inspected, to pass through it and the resulting image is captured on a film. This film is in-turn processed and image displayed as a sequence of gray shades between black and white.
With radiographic examination the material is exposed to a homogenous ray from a radioactive isotope or an X-ray tube, while a negative film is positioned behind the material to be examined. After development of the film, thickness and density differences (i.e. material imperfections) will show as blackness differences. Acceptance criteria define whether or not the indication is non-acceptable (a defect) or not.
Application Range
Radiography encompasses sources such as X-rays, Gamma rays as well as newer methods such as Real Time Radiography, Computed Radiography (CR) and Computed Tomography (CT). Not one solution can meet all radiographic needs. The right choice depends upon the application.
