880 Sigma Source Projector

A lightweight,portable and compact industrial radiographic device

SENTINEL Model 880 Delta, 880 Sigma, 880 Elite and 880 Omega source projectors are portable, lightweight and compact industrial radiographic exposure devices. The patented 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 to provide protection for the rear mounted locking mechanism and front mounted outlet port.

Model 880 series source projectors are used for industrial applications of gamma
radiography, mainly with Iridium-192, to inspect materials and structures in the
density range of approximately 2.71g/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.
