DANGER – IMPORTANT WARNINGS
These transport containers must only be used for radiography source assemblies that are approved for use. Please
refer to Tables 1 & 2 for a listing of source assemblies that are authorized for use in each design. The containers
must be operated only by trained and qualified radiographers who have read and understand this Operating Manual
or by trained assistants working under their direct supervision.
WARNING
The use of these radiographic gamma-ray source projectors by unqualified personnel or when safety
procedures are not fully met, could result in life-threatening dangers.
Do not use these containers for unauthorized, damaged or cropped source assemblies.
The radioactive source assemblies utilized in these containers emit high levels of highly penetrating radiation during
use.
An unshielded radiation source at close range can cause injury, sickness or death to anyone who is exposed to it
even for a short period of time.
A radiation source must not be touched by the hands under any circumstances.
Since gamma radiation cannot be detected by the human senses, strict operating and emergency procedures must
be followed. The proper use of calibrated and operable survey meters must be employed to avoid potentially
dangerous levels of radiation exposure.
Proper dosimetry including film badges or thermoluminescent dosimeters, optically stimulated luminescence badges
(OSL); direct reading pocket dosimeters and audible alarm ratemeters must be worn during all radiographic
operations.
It is imperative that the users of these containers perform adequate radiation surveys of the gamma-ray source
projector. Surveys must be performed using a calibrated survey instrument before, during and after source
exchanges, source exposures, and before transport to determine if the source assembly is properly shielded within
the container. The failure to perform an adequate radiation survey can cause unnecessary exposure to personnel
resulting in a reportable incident.
It is very important, and required by national regulations, to prevent access by unauthorized persons to radiographic
equipment and to the area where radiography is performed.
Take advantage of the three basic radiation protection methods to minimize radiation exposure:
Time: Spend less time near the radiation source.
Distance: Increase your distance in a direction away from the radiation source.
Shielding: Use effective shielding between you and the radiation source.
Do not perform any unauthorized modifications to the radiographic gamma-ray source projector or components of
the radiography system.
It is important that trained and qualified radiographers perform or supervise a daily safety inspection of the
radiography system for obvious defects prior to operation of the system.
Do not use any components that are not approved for use with the radiography system, or after-market components
that ma

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.

1.3 Applications & Authorized Contents
The SENTINEL SENTRY 110 and SENTRY 330 are radiographic gamma-ray source projectors used for
industrial applications of gamma radiography with Cobalt-60 to inspect materials and structures. They
are intended for industrial gamma radiography of various materials in the following approximate thickness
range:
Steel from 2 to 8 inches (50-200 mm)
Light alloys from 1.5 to 7.5 inches (40-190 mm)
Concrete from 10 to 40 inches (200 to 1,000 mm)
Compacted metallic Cobalt-60 pellets are doubly encapsulated in welded stainless steel or titanium
capsules. The sealed sources are designed and tested to achieve an ISO/ANSI minimum classification of
97C64515 and to comply with the IAEA and USDOT requirements for ‘Special Form’ radioactive material.
The ISO/ANSI classification 97C64515 stated in this manual refers to the complete source capsule which
is attached to the source assembly.
The double-encapsulated sealed source is swaged to one end of a source holder consisting of a flexible
steel cable which has a female half of a connector at the other end, used for coupling to a control cable
connector. The female connector also incorporates a stainless steel stop-ball swaged onto it (older
versions of this source wire had the stop-ball as a separate component from the female connector). The
purpose of the stop-ball is to provide mechanical positioning of the source assembly within the gamma-
ray source projector’s shielding and to provide a means of securing the source assembly in the gamma-
ray source projector’s locking mechanism.

1.4 Operating Distance
The distance between the remote control and the exposure head is determined by summing the length of
the remote control conduits plus the total length of source guide tubes used, and normally should not
exceed 47 ft (14.2 m) with standard 25 ft. controls.
Standard lengths of remote controls: 25 ft (7.6 m), 35 ft (10.7 m), 50 ft (15 m)
Standard lengths of guide tubes (projection sheaths): 7 ft (2.1 m) - three guide tubes, 21 ft total (6.4 m)
WARNING
The total length of source guide tubes utilized must be shorter in length than the remote controls to
ensure the source assembly will project into the working position.
e.g. When using 25 ft (7.6 m) remote controls, a maximum of three 7 ft (2.1 m) source guide tubes can
be used with a combined length of 21 ft (6.4 m).
Conversely, when using 35 ft (10.7 m) remote controls, a maximum of four 7 ft (2.1 m) source guide
tubes can be utilized.
When using 50 ft (15 m) remote controls, a maximum of six 7 ft (2.1 m) source guide tubes can be
utilized. This limitation is due to the weight and friction of remote control cable length.
