COBALT-60 INDUSTRIAL RADIOISOTOPES

SENTINEL™ Cobalt-60 Industrial Radioisotopes.

QSA Global, Inc. is the world-leading supplier of SENTINEL Cobalt-60 (Co-60) sealed radioisotope sources to the industrial gamma radiography industry. Our exclusive and diversified supply chain ensures a reliable, long-term supply of SENTINEL Co-60 to our customers.

QSA Global, Inc.’s SENTINEL Co-60 radioisotope sources are compacted High Specific Activity (HSA), double-encapsulated, and laser welded for superior quality and safety. 

Our SENTINEL Co-60 radioisotope sources are available in 300 Ci (11.10 TBq) activity. Custom activities may be ordered to meet your specific application needs. 

Designed, tested, and manufactured to the requirements of ISO 9001/EN46001


SENTINEL Co-60 in Gamma Radiography

Cobalt is used throughout the industrial radiography industry to detect structural damage to metal parts. QSA Global, Inc.’s SENTINEL Co-60 radioisotope sources are used to perform industrial gamma radiography with relatively short exposure time on thicker materials such as heavy castings, thick steel weldments, and concrete.

SENTINEL Co-60 Gamma-Ray Source Projectors
QSA Global, Inc.’s SENTINEL Co-60 radioisotope sources are generally in the configuration of a right circular cylinder with an end mounted hemisphere of equivalent diameter. The active material is coaxial with the source capsule. QSA Global, Inc.’s SENTINEL Co-60 isotope assemblies were designed specifically for use in our SENTINEL Co-60 gamma radiography source projectors to perform weld quality inspection in Fabrication Shops and Shipyards and to investigate the condition of large valves in piping systems. SENTINEL Co-60 radioisotopes are available for the following current and previous SENTINEL Co-60 gamma-ray source projectors.
