Iridium-192 Industrial Radioisotopes

Iridium-192 (Ir-192) is a radioisotope created from the element, Iridium, that emits gamma rays from 0.26 MeV to 0.612 MeV.  This energy range of gamma rays emitted makes Ir-192 ideal for industrial radiography.  Industrial radiography is the practice of using ionizing radiation to view internal flaws in objects such as pipelines to verify the integrity of welds.  Industrial radiography using Ir-192 has become a major element of non-destructive testing.

Ir-192 is used in conjunction with our SENTINEL™ 880 series projectors to inspect materials and structures in the density range of approximately 2.71 g/cm3 to 8.53 g/cm3.  During a radiographic exposure using Ir-192, an image of the material being inspected is captured on a digital panel, phosphor plate, or film.  Ir-192 can be used to inspect pipeline welds, castings, forgings and many other industrial subjects.
