The SENTINELTM range of double encapsulated special form sealed source assemblies caters to most industrial applications using gamma radiography.

A choice of isotopes provides solutions for the widely varying requirements demanded by different materials and site conditions. Sources with outputs ranging from less than one curie up to several hundred are available; all precision constructed to ensure the highest possible specific activities and the smallest focal spot sizes.

Source exchange is available as a service either on-site or when source projectors are returned to SENTINELTM for inspection or overhaul. Sources can be shipped in the source projector or in a suitable returnable transport container.

Cobalt-60 sources are constructed using compres sion fused cobalt metal pellets confined within welded titanium and stainless steel capsules.

INC-IR100 uses Source Model # 87703, and SPEC-150 uses Source Model # 96901

1 Selenium-75 and Iridium-192 use the 650L Source Changer, while Cobalt-60 uses the 770 Source Changer.
