Radiographic examination is a nondestructive testing (NDT) method that uses ionizing radiation, such as X-rays or gamma rays, to inspect the internal structure of materials. It is widely used in the fabrication and inspection of pressure vessels, boilers, and piping systems to detect defects, such as cracks, porosity, and inclusions.
