Applications
Model 880 series exposure devices are used for industrial applications of gamma radiography, mainly with Iridium-192, to inspect materials and structures in the density range of approximately 2.17 g/cm3 through 8.53g/cm3. Low energy isotopes can be accommodated to permit radiography of materials and structures of thin sections of steel and low-density alloys.

The 880 series exposure devices are also designed for use with low activity sources with high photon energies for mass absorption (gamma scanning) studies of high-density materials up to 18.7g/cm3.

Exposure Device

SENTINEL Model 880 source projectors are portable, lightweight and compact industrial radiographic exposure devices. The exposure device body consists of a titanium ‘S’ tube and cast Depleted Uranium (DU) shield contained within a 300 series stainless steel tube with stainless steel discs welded at each end forming a cylinder shaped housing. The discs are recessed o provide protection for the rear mounted locking mechanism and front mounted outlet port.

The horizontally oriented design allows the locking mechanism, source assembly connector and outlet port to be easily operated, simplifying the connection of source guide tubes and projection sheaths.

The internal void space of the housing s filled with rigid foam to prevent the ingress of water or foreign material, but is open to atmospheric pressure.

The exposure device body, containing the DU shield, locking mechanism, outlet port, protective covers and requires labels, comprises the radioactive material transport Type B package*.

The Sentinel 880 series source project is available in 2 models:

• Delta 150 Ci – The lightest 150 Ci device currently available.

• Elite 50 Ci – Idea for use with low-energy isotopes and lower activity Ir-192 sources.
