The SENTINEL 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 SENTINEL for inspection or overhaul. Sources can be shipped in the source projector or in a suitable returnable transport container.

Selenium – 75 sources are available in cylindrical and quasi-spherical focals, permitting shorter SFDs and greater sensitivity on fixed geometries.

IRIDUM – 192
Iridium – 192 sources are constructed using iridium metal discs or pellets of uniform size in a welded stainless steel capsule.

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