Co-60 in Gamma Radiography

Cobalt-60 sealed sources are used throughout the industrial radiography industry to detect structural damage to metal parts. QSA Global, Inc.’s Co-60 sealed 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.

Co-60 Gamma-Ray Source Projectors

QSA Global, Inc.’s Co-60 sealed 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 Co-60 isotope assemblies were designed specifically for use in our 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.
