Selenium-75
Safety is our priority. The radioisotopic sources QSA Global, Inc. are made of a selenium metal alloy contained in a vanadium capsule, providing the highest thermal stability, physical strength and durability compared with common elemental Se-75. SENTINEL Se-75 sources are available with maximum focal sizes from 1.0 to 3.5 mm and with typical nominal activities up to 90 Ci (3.33 TBq).
Selected Se-75 sources are single encapsulation.

The advantages of Selenium-75
Superior quality and safety
QSA Global, Inc.'s SENTINEL Se-75 radioisotope sources are double encapsulated and sealed by laser welding to ensure maximum quality and safety. The sources contain an almost spherical metal pellet which allows to obtain the smallest possible focal size, reducing the Source-Film Distance (SFD) and increasing the sensitivity on fixed geometries.
Focal size and nominal activity
QSA Global, Inc.'s Se-75 radioisotope sources are available in maximum focal sizes from 1.0 to 3.5 mm and with typical nominal activities up to 90 Ci (3.33 TBq).
Transport of radioactive sources
QSA Global, Inc. distributes radioisotope sources worldwide using the industry's largest fleet of source changers. Source changers are available to transport from a single source to up to ten sources in a container, for charging the device at your facility or at one of QSA Global, Inc.'s authorized service centers.
Loading and unloading options
