What is Radiographic Testing?

Radiographic Testing (RT) is a nondestructive testing (NDT) method that uses X-rays or gamma rays to look inside an object and check for hidden defects. When radiation is directed at the object, some of it is absorbed, some is scattered, and some passes through. The radiation that makes it through is captured by a detector.

Most radiographic testing methods use special film that records an image when exposed to radiation. Other detectors, like digital imaging plates, are also used, and new imaging technologies continue to be developed. RT is commonly used to inspect welds, castings, and other materials for internal flaws without damaging them.
