Radiographic inspection is a non-destructive method of detecting hidden flaws in
materials, solid objects and fabrications. It then provides a permanent record
of what it finds.
Radiography is particularly good at identifying volumetric flaws such as voids,
gas pores and
solid inclusions.
The system works by positioning a source of ionising radiation at one side of
the item to be inspected and a photographic film at the other. Full size images
|
showing internal detail are then recorded on the film. Processed films are called radiographs.
Radiography uses either X-rays or gamma rays, depending on the thickness of the
material to be tested. Gamma sources have the advantage of portability. X-rays
are generated by means of high-voltage X-ray tubes. Gamma rays are produced by
the natural disintegration of nuclei in a radioactive isotope. Both methods require highly skilled personnel. All of our technicians are fully
qualified and have the latest technology at their disposal.
