WebRadiographic Inspection involves the use of penetrating X or gamma radiation to examine parts and products for imperfections. An x-ray machine or radioactive isotope is used as a source of radiation, and is directed through a part and on to film. When the film is developed, a radiograph is obtained that shows the internal soundness of a part.
