Radiographic Inspection and Interpretation

Radiography (RT) and Radiographic Interpretation (RI) uses X-rays or gamma-rays to produce an image of an object on film.

The image is usually natural-size. X-rays and gamma-rays are very short wavelength electromagnetic radiation which can pass through solid material, being partly absorbed during transmission. Thus, if an X-ray source is placed on one side of a specimen and a photographic film on the other side, an image is obtained on the film of the thickness variations in the specimen, whether these are surface or internal. This is a well-established technique which gives a permanent record and is widely used to detect internal flaws in weldments and castings and to check for mis-constructions in assemblies.
