Sentinel Iridium-192 Industrial Radioisotopes

Our SENTINEL Ir-192 radioisotope sources are available up to 240 Ci (8.88 TBq) activity.

Part # Ir-192 Category Tags ,

The SENTINEL Ir-192 radioisotope sources are available up to 240 Ci (8.88 TBq) activity. Custom activities may be ordered to meet your specific application needs.

QSA Global, Inc.’s SENTINEL Ir-192 radioisotope sources are double-encapsulated and laser welded for superior quality and safety. Natural and enriched Iridium-192 sources are constructed using iridium metal discs or pellets of uniform size in a welded stainless steel capsule. Utilizing enriched Ir-192 produces smaller focal sizes for optimum image quality.

SENTINEL Ir-192 is designated for use within the steel thickness range of 0.39 in-3.54 in (10 mm-90 mm) per ISO 5579:2013

Transportation, Support, & Disposition

Transporting Isotopes

QSA Global, Inc. distributes radioisotope sources worldwide by utilizing the industry’s largest fleet of source changers.  Source changers are available to deliver a single source up to ten sources in a container for device reloads at your facility or at one of QSA Global, Inc.’s authorized service centers.

Loading & Unloading

QSA Global, Inc. offers a variety of options for SENTINEL Ir-192 source changes to minimize downtime of your assets.  QSA Global, Inc. and our authorized distributors can reload your SENTINEL Ir-192 device at local facilities around the world by trained technicians or sources can be delivered directly to your facility for reload by your trained technicians.

Isotope Disposition

Radioactive materials that are no longer required must be transferred to a licensed recipient for final disposition. QSA Global, Inc. provides a one for one exchange on SENTINEL Ir-192 radioisotope sources.

SENTINEL Ir-192 in Gamma Radiography

Iridium is also used throughout the industrial radiography industry to detect structural damage to metal parts. QSA Global, Inc.’s SENTINEL Ir-192 radioisotope sources are used to perform industrial gamma radiography on materials such as castings, forgings, and weld defects
