Radiography Testing


Radiographic Testing (RT) is a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation to penetrate various materials. In Radiography Testing the test-part is placed between the radiation source and film (or detector). The material density and thickness differences of the test-part will attenuate (i.e. reduce) the penetrating radiation through interaction processes involving scattering and/or absorption. The differences in absorption are then recorded on film(s) or through an electronic means. There are two different radioactive sources available for industrial use; X-ray and Gamma-ray.


Our solution 

AlphaNDT’s RT can be provided as the inspection solution for weld quality, corrosion, erosion, cracks and loss of wall thickness, material deposits and blockages of new construction and in-service inspection.


AlphaNDT’s on-site RT can also provide the use of close-proximity radiography by using SCAR (Small Controlled Area Radiography).
