Radiography is used to examine parts for internal imperfections using penetrating Gamma or X-ray. An X-ray generator or a radioactive isotope is used as the source of radiation. Radiation is directed through a test area and onto a film, through which an imperfection is indicated by a change in density on the film. These results in the clear detection of imperfections as they are more visible when compared to the results of the Ultrasonic Flaw Detection.
- All types of materials can be inspected
- Produces the permanent evidence (radiography film)
- Length of the defect can be sized
