1.2 General Gamma-Ray Source Projector Description

The SENTINEL SENTRY 330 and SENTINEL SENTRY 110 are mobile industrial radiography gamma-ray
source projectors and are identical in size and shape, but differ in the total weight, maximum capacity and
color of the lifting and securing provision. These devices include a handling rib assembly that provides a
means for lifting and securing the gamma-ray source projectors. These devices incorporate an 'S' tube
design depleted uranium (DU) shield contained within a welded stainless steel construction and utilize an
automatic securing mechanism to secure the sealed source assembly in the stored position after full
retraction into the gamma-ray source projector. Both the lock assembly and the front plate assemblies
are protected by stainless steel tube extensions welded to the device main body.
The front and rear plate port weldments are designed to provide easy access to the locking mechanism
and source assembly connector and to provide easy access to the outlet port for connection of the
projection sheaths. The outlet port is designed to permit the attachment and the removal of projection
sheaths without an elevation of measurable radiation. 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 device which also serves as a
Type B(U) transport package.
The devices include a handling rib assembly to increase ease of lifting and securing. The devices are
compliant to all industry standards referenced in this manual as well as the requirements of a Type B(U)
package with or without the handling rib assembly attached. (Note: Although the devices are compliant
for Type B(U) shipment with or without the rib assembly attached, ONLY the devices WITH the handling
rib assemblies attached are compliant to the operational ANSI/ISO standards referenced below. For easy
recognition, the SENTINEL SENTRY 330 is equipped with a yellow handling rib assembly and the
SENTINEL SENTRY 110 is equipped with a blue handling rib assembly.
The SENTINEL SENTRY 330 and SENTINEL SENTRY 110 gamma-ray source projectors are designed,
tested, and manufactured to meet the requirements of ANSI N432-1980, ISO 3999:2004(E), IAEA TS-R-1
(1996 Revised), USNRC 10 CFR 34, 10 CFR 71 and 49 CFR 173 requirements. Additionally, these
gamma-ray source projectors are designed, manufactured and serviced under an ISO 9001 QA Program
and a USNRC 10CFR71, Subpart H QA Program. The QA program also includes the reporting
requirements of USNRC 10 CFR 21 for suppliers of source and byproduct materials.
