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.

2. OPERATING INSTRUCTIONS.
2.1 Job Site Safety Precautions
Instruments
The radiographer and radiography assistants must at all times wear a film badge or TLD and pocket
dosimeter with a range of 0-2 mSv (0-200 mRem). Regulatory requirements in the USA also require that
an audible alarm ratemeter be worn at temporary jobsites. Specifically, those locations that are not
permanent radiographic installations equipped with functional door interlocks and audible/visual alarms.
Radiographers in the USA must also have a survey meter capable of measuring in the range
20 µSv/hr (2 mR/hr) up to 10 mSv/hr (1,000 mR/hr). Canadian regulations require that survey meters
used for industrial radiography be capable of measuring from 2 µSv/hr (0.2 mR/hr) and up to 100 mSv/hr
(10 R/hr). In any regulatory jurisdiction, always verify survey meter requirements affecting the range and
calibration requirements prior to engaging in industrial radiography operations.
An audible ‘chirper’ pocket alarm may be required in some countries.
Restricted Area
Radiography must be performed only in a restricted area that is marked with the appropriate radiation
warning signs and secured against unauthorized entrance.
Distance
Since the source emits high levels of radiation it is good practice to operate the system from as great a
distance as possible.
Shielding
Whenever possible, situate the radiographic exposure area in a room with suitably thick walls, floor,
ceiling and doors. Whenever possible, the use of a collimator (beam limiter) provides effective shielding to
reduce radiation levels outside of the central beam. It is recommended that collimators be used at
temporary job sites to minimize occupational exposure to radiation.
Surveillance
Only trained and qualified radiographers or their assistants working under their direct supervision may
operate radiography systems. The radiographer must be physically present at the site and able to control
and limit access to the restricted area.
Locking
Keep the gamma-ray source projector locked while assembling the system and when not being used to
perform radiography. Locked is defined as the gamma-ray source projector's lock is fully engaged with
the key removed. Store the key in a secured location.

2.2 Operational Instructions
WARNING
It is essential that the 5 STEPS set out below are followed in the correct order to
ensure safe operation and compliance with regulations.
STEP 1 Gamma-ray source projector Survey
STEP 2 Connecting the Source Guide Tube(s)
STEP 3 Connecting the Remote Control Cable
STEP 4 Projecting and Retracting the Source Assembly
STEP 5 Dismantling Equipment
STEP 1
Gamma-ray source projector Survey
Protection against radiation incidents begins with proper survey meter use. Operators must inspect
the survey instrument to verify that it is operating properly in accordance with 10 CFR 34.31 and
applicable company specific operating procedures.
Check the operation of the survey meter by measuring the radiation level at the surface of the
gamma-ray source projector. The radiation level measurement should not exceed 2 mSv/hr (200
mR/hr) on any surface of the gamma-ray source projector. Use this measurement for verification
surveys of the source assembly’s return to the fully shielded/secured position within the gamma-ray
source projector after each radiographic exposure.
(Perform a daily inspection of all equipment used according to the daily inspection section.)
STEP 2
Source Guide Tube (projection sheath) Layout
Ensure all source guide tubes that will be utilized have received a daily inspection according to the
daily inspection section of this manual. Position and secure the source stop (exposure head) of the
terminating source guide tube at the radiographic focal position using the tripod stand and swivel
clamps or some other secure and suitable means.
Ensure that a source stop (end stop) is in place on the terminating source guide tube.
Use a collimator (beam limiter) to limit the primary beam in unwanted directions.
Determine where the gamma-ray source projector will be positioned and lay out the source guide
tubes as straight as possible, with no bend radius less than 20 in (0.5 m) to avoid restricting the
movement of the source assembly.
Make sure that the source guide tubes do not contact any heated surface greater than 140°F (60°C).
Avoid any risk of crushing the source guide tube(s) by falling objects, vehicles or doorways during
set-up and during radiographic exposure.

STEP 2 Continued
Connecting the Source Guide Tube(s)
The source guide tubes must always be attached to the outlet port of the device before connecting
the remote controls in the set-up for a radiographic exposure.
Connect the source guide tube(s) to the gamma-ray source projector outlet port.
Simultaneously pull and rotate the spring-
loaded outlet port cover a quarter of a turn in a
clockwise direction
Insert the bayonet fitting of the source guide
tube into the exposed outlet port.
Align the GREEN MARKINGS on the bayonet
connector and the outlet port.
Rotate the bayonet a quarter of a turn counter-
clockwise.
Rotate the spring-loaded outlet port cover an
additional 60 degrees in a clockwise direction
until it stops.

WARNING
Ensure that the available length of the control cable is greater than the total length of the
source guide tubes. See the technical specifications section for details.
If the remote control conduits are shorter than the total length of the source guide tubes:
1 The source assembly cannot be projected all the way to the source stop of the terminating
source guide tube and be correctly positioned for the exposure.
2 The source assembly may not reach a collimator; therefore, restricted area dose rates may be
higher than expected.
3 The control cable end may be cranked beyond the drive wheel of the remote controls if the drive
cable is not be fitted with a safety retaining spring. This scenario must be treated as an
EMERGENCY.
STEP 3
Remote Control Conduit Layout
Lay out the remote control conduits as straight as possible, with no bend radii less than
approximately 36 in (approximately 1 m).
Avoid any risk of crushing the remote control conduits by falling objects, moving vehicles or
closing doors, etc.
The remote control crank mechanism (operator's hand-crank) should be placed as far away from
the source focal position as possible (preferably behind shielding).
Connecting the Remote Control Cable
Connect the control cable to the source projector as shown.
Unlock the plunger lock with the key.

STEP 3 Continued
The protective cover will disengage from the
projector.
Secure the lock protective mechanism’s cover on
its bracket located above the locking mechanism.
Remove protective rubber cap from the remote control
connector.
Check the control cable and source assembly connectors
using the NO GO gauge according to the daily inspection
section.
IMPORTANT WARNINGS!
The control cable connector is made from
hardened steel and should never be left
unprotected or forced into connection with the
source assembly connector as this could
damage the connector over time, leading to
possible breakage during use.

STEP 3 Continued
Connecting the Remote Control Cable
ALWAYS use the protective rubber cap whenever the
remote controls are not connected to the gamma-ray
source projector.
ALWAYS manually move the inner sleeve of the
female connector of the source assembly to the
OPEN position when connecting and disconnecting
the control cable from the source assembly.
Slide the remote control connector assembly’s collar back
and open the jaws to expose the male portion of the
control cable connector (i.e. the ball-end on the control
cable connector).
Press back the spring-loaded locking pin of the source
assembly connector with a thumb-nail and engage the
male and female portions of the connectors.
Release the locking pin of the source assembly connector
and check that the connection is secure. (In low light
conditions, a gentle wag side-to-side and up and down
will provide confirmation of a secure connection).
Use the NO GO gauge to check the gap between the
joined connectors according to the daily inspection
section.
NOTE: The control cable connector, when properly
installed with the selector ring in the CONNECT position,
displaces anti-rotation lugs which allows the selector ring
to be rotated to the LOCK position and when required,
through to the OPERATE position.
Push and hold the remote control connector assembly
collar flush against the gamma-ray source projector’s
locking mechanism and rotate the selector ring from
CONNECT to LOCK.
Do Not Rotate past LOCK.
The remote control cable connector is now secured into
the gamma-ray source projector’s locking mechanism.
Keep the gamma-ray source projector in the lock position
until ready to start the exposure.
