Sentinel Natural and Enriched Iridium-192

Ir-192 is used in conjunction with our SENTINEL™ 880 series exposure devices 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.

Description

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 nondestructive testing.

Ir-192 is used in conjunction with our SENTINEL™ 880 series exposure devices 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.

Our double-encapsulated, natural and enriched sealed Ir-192 sources are constructed by stacking iridium metal discs of uniform size in a source capsule to form a right-circular cylinder. The Ir-192 source capsule components are constructed of stainless steel, hermetically sealed by laser welding and finished to exacting standards. Each Ir-192 source is swaged to one end of a source holder consisting of a short flexible steel cable which has a connector at the other end for coupling to a control cable.  A stainless steel stop-ball is also incorporated into the Ir-192 source wire assembly .The stop-ball provides mechanical positioning of the Ir-192 source assembly within the Model 880 exposure device’s shielding.  It also provides a means of securing the Ir-192 source assembly in the Model 880 exposure device’s automatic securing mechanism.

Every capsule is subjected to a series of quality inspection tests to ensure weld integrity and uniform wall thickness.  The sealed Ir-192 sources are designed and tested to achieve an ISO/ANSI minimum classification of 97C64515 and to comply with the IAEA and USDOT requirements for ‘Special Form’ radioactive material.  The ISO/ANSI classification 97C64515 refers to the complete Ir-192 source capsule which is attached to the source assembly.
