Exposure device description
The Model 880 Delta, Model 880 Sigma and Model 880 Elite are physically small,
lightweight, portable industrial radiographic exposure devices. The ‘S’ tube design exposure
device consists of a cast depleted Uranium (DU) shield contained and secured within a
300 series stainless steel tube with stainless steel discs welded at each end to form a cylinder
shaped housing. Both discs are recessed into the stainless steel tube to provide protection
for the locking mechanism at the rear side and the outlet port at the front side.
The welded tubular housing is oriented horizontally to provide easy access to the locking
mechanism and source assembly connector and to provide easy access to the outlet port for
connection of projection sheaths. The internal void space of the welded housing is filled
with polyurethane foam to prevent the ingress of water or foreign material but is open to
atmospheric pressure. The stainless steel housing containing the DU shield, locking
mechanism, outlet port, protective covers and required labels comprise the radioactive
material transport package.
A plastic jacket surrounds the welded housing and serves as a protective barrier for the labels
and provides the means for carrying and placement during use as a radiographic exposure
device. The Model 880 Delta is identified by a yellow colored jacket, the Model 880 Sigma is
identified by a black colored jacket and the Model 880 Elite is identified by a blue colored
jacket. The plastic jacket incorporates a carrying handle and a base that is used during
radiographic operations but is not required for transportation purposes. The plastic jacket may
be removed for certain applications such as when the exposure device is securely mounted
to a pipe-crawler locomotive or a pipe-liner sled.
The Model 880 Delta, Sigma and Elite exposure devices are designed, tested, manufactured to
meet the requirements of ANSI N432-1980, ISO 3999-1:2000(E), IAEA-ST1, IAEA TS-R-1 (1996),
USNRC 10CFR34, 10CFR71 and 49CFR173 requirements. Additionally, the exposure device is
designed, manufactured and serviced under a ISO 9001 QA program and a USNRC 10CFR71,
Subpart H QA program. The QA program also includes the reporting requirements of
USNRC 10CFR21 for suppliers of source and byproduct materials.
