It is based on differential absorption of penetrating radiation by the part being inspected. The degree of absorption depends upon the thickness as well as physical density variations in the object. The forms of penetrating radiation that are used in radiographic inspection of pressure vessels and valves are X-rays and Gamma rays. X-rays are generated in vacuum tubes when metals like tungsten stop accelerated electrons. Gamma rays originate from artificially produced radioisotopes when elements such as iridium and cobalt are treated in a reactor with a flux of neutrons.

SITAS successfully executed a order for carrying out Radiographic test on 8 nos Horton spheres in Cairo, Egypt using the panoramic method, the first of its kind in Egypt. SITAS inaugurated its new NDT and casting up-gradation facility in Coimbatore with two enclosures to operate 100 curie Co-60 isotopes, four enclosures to operate 100 ci I-192 isotopes, training room to accommodate 40 students, MPI using 4000 amps etc. This facility is rated as the biggest in the whole country spread over 2 acres. SITAS inaugurated its new NDT and casting up-gradation facility in Shimoga with Co-60 & Ir-192 enclosures in Karnataka on 14th December 2011.
