Radiographic testing uses radiation passed through a test piece to detect defects. X-rays are commonly used for thin or less dense materials while gamma rays are used for thicker or denser items. The results can be processed using film radiography, computed radiography, computed tomography. Whichever method is used, the radiation will show discontinuities in the material due to the strength of the radiation
Radiographic Testing (RT) is a non-destructive testing (NDT) method that uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between the radiation source and film (or detector).
