Sentinel Selenium-75 Industrial Radioisotopes
Only by Request
Our SENTINEL Se-75 radioisotope sources are available in maximum focal sizes ranging from 1.4 mm to 3.5 mm and nominal activities up to 100 Ci. (3.7 TBq).
Radioisotope sources contain a quasi-spherical metallic pellet for the smallest possible focal dimension which minimizes Source-Film-Distance (SFD) and heightens sensitivity on fixed geometries.
Safety is our top priority. QSA Global, Inc. radioisotope sources are made of a patented vanadium-selenium metal alloy producing the highest possible thermal stability combined with physical strength and durability compared to commonly used elemental Se-75.
Our SENTINEL Se-75 radioisotope sources are available in maximum focal sizes ranging from 1.4 mm to 3.5 mm and nominal activities up to 100 Ci. (3.7 TBq).
SENTINEL Se-75 is designated for use within the steel thickness range of 0.20 in-1.57 in (5 mm-40 mm) per ISO 5579:2013.

SENTINEL Se-75 Gamma-Ray Source Projectors
Small, light-weight SENTINEL Se-75 exposure devices can be used in difficult to access locations that x-ray generators cannot go due to their size, weight, and power requirements.
SENTINEL Se-75 is the preferred isotope for our SCAR exposure devices to enable the safety exclusion zone at worksites to be minimized during radiographic exposures in congested areas.
QSA Global, Inc.’s SENTINEL Se-75 radioisotope sources are also designed for use in our 880 Series projectors for traditional radiography.
