Source Radio-isotopes SENTINEL™ Sélénium-75

The radioisotope sources from QSA Global, Inc. are made of a patented vanadium-selenium metal alloy that provides the highest possible thermal stability combined with physical strength and durability compared to commonly used elemental Se-75.

The SENTINEL Se-75 radioisotope sources from QSA Global, Inc. are ideal for controlling exclusion zone size during radiographic exposures in congested work sites.

SENTINEL Se-75 radioisotope sources are used on offshore oil platforms and in power plants during outages to reduce exposure to non-professional workers.
