2.1 Proper use
The source with shield is used in connection with a detector and a suitable
evaluation unit provided by BERTHOLD TECHNOLOGIES to measure the radiation
intensity occurring during a radiometric measurement.
The shield was developed as shield/protective container for radioactive sources
and may be used exclusively for this purpose.
Usually, the shield contains a radioactive source. The notes on radiation
protection contained in the present manual as well as any statutory requirements
in this respect are to be strictly adhered to.
The following constitutes proper use:
• Adhering strictly to the instructions and operation sequences and not
undertaking any different, unauthorised practices which could put your safety
and the operational reliability of the shield at risk!
• Observing the provided safety instructions!
• Carrying out the prescribed maintenance measures or having them carried out
for you!
The following constitutes improper use and is to be avoided:
• Any non-compliance with the present operating manual for the supplied
products
• Applying conditions and requirements which do not conform to those stated
in the technical documents, data sheets, operation and assembly instructions
and other specific guidelines of the manufacturer.
• Using the product after any repair carried out by employees who have not
been authorized by BERTHOLD TECHNOLOGIES GmbH & Co. KG.

2.2 Ambient conditions during operation and storage
The shield was specifically designed for use in rough ambient conditions. The
compliance with the operating conditions specified below contributes to
guaranteeing the permanent functionality of the shield and the prevention of
damage.
Shields containing radioactive substances and sources are to be stored in a
lockable storage room complying with the national requirements as regards the
storage of radioactive substances.
Furthermore, the following prescribed ambient conditions are to be observed:
• The minimum admissible operating/storage temperature is -40°C. Below this
temperature, the sealing rings of the shield may become brittle. In such case,
the leakproofness of the shield can no longer be guaranteed.
• The maximum admissible operating/storage temperature is +100°C. Above this
temperature, the sealing rings of the shield may be destroyed. In such case,
the leakproofness of the shield can no longer be guaranteed.
• The higher the dust and dirt content of the environment, the more likely
stiffness or an entire blockage of the locking mechanism is. For this reason, the
functional test intervals (see chapter 6) should be adjusted to the ambient
conditions.
• Highly combustible or explosive substances must not be kept in the vicinity of
shields in order to prevent a fire from spreading to the radioactive substances.
2.3 Qualification of the personnel

2.4 Radiation Protection
2.4.1 Basic principles and regulations
The amount of radiation absorbed by the body (exposure to radiation) is
determined by three parameters from which the basic radiation protection
regulations can be derived:
Distance
If work close to equipment containing
radioactive substances is required, the
largest distance possible is to be kept. In
particular, this shall apply for employees
which do not immediately participate in
such work.
Time
Any
work required in the vicinity of
radiometric measuring systems is to be
prepared carefully and to be organised
in a way that the work can be executed
as quickly as possible. Here, providing
the correct tools and aids is particularly
important.
Shield
W
hen mounting and dismounting the
shield, it is to be ensured in advance that
the radiation beam outlet is closed.
2 Safety manual Rod source shields LB 8300
14
64217BA2 Rev. 00, 10/2017
2.4.2 Exposure of employees to radiation
During installation, maintenance and decommissioning of the shield, employees
may be exposed to radiation.
In order to keep such exposure as low as possible, the shield with the source may
only be mounted and/or dismounted by authorized employees. Such authorised
staff is to be instructed as regards all rules of behaviour when handling
radioactive substances in advance.
It is to be ensured that the locking mechanism of the shield is closed and secured
in order to prevent the emission of unshielded radiation. Modification or damage
to the shield must be avoided at all times.
Work may only be executed according to the instructions and under the
supervision of the radiation safety officer, who furthermore has to calculate or
estimate the exposure of the employees to radiation in order to ensure that the
statutory dose rate limits are not exceeded.
2.4.3 Theft protection
Radioactive substances or equipment containing radioactive substances must be
secured in a way that they are protected against access by unauthorized persons.
In the case of firmly installed equipment containing radioactive substances, the
protection against unauthorized access is generally provided by the firmly
attached installation.
Shields with radioactive sources which are decommissioned for a certain period of
time must be dismounted and securely stored in a storage room complying with
the national regulations as regards the storage of radioactive substances.
Portable measuring systems must never be left unsupervised. When this
equipment is out of use, it is to be protected against access by unauthorised
persons.
2.4.4 In the case of fire
The shield material can melt and leak from the shield if exposed to very high
temperatures for an extended period of time. During and after a fire, there is a
risk of major long-time consequences for your health due to the incorporation of
lead as well as a risk of increased radiation exposure.
When planning the use of radiometric measuring systems, constructional
measures ensuring fire prevention are to be provided.
In the case of fire, these measures limit the access to this area.
Avoid the incorporation by keeping sufficient distance.
Notify BERTHOLD TECHNOLOGIES of the situation; you will promptly receive
information on immediate measures.

64217BA2 Rev. 00, 10/2017
3 System Description
The rod source shield is intended as shield/protective container for radioactive
rod sources. The radioactive substance is contained in a leak-proof welded source
capsule and installed in the rod source shield. Apart from source and shield,
additional system components such as detectors and evaluation units are required
for a complete measuring system. Usage of these system components is not
subject of this operating manual. Please refer to the individual manuals of the
respective system components.
The shield container consists of a robust steel housing filled with lead. The
locking cylinder of the shield is pivoted. The provided lever rod can be used to
turn the locking cylinder to the two end positions. The radiation beam outlet is
thereby opened and closed.
The locking plate on the upper side of the shield ensures that the source cannot
be removed by unauthorized persons. Operators can secure the locking plate by
installing a padlock at the right-hand and the left-hand side.
The locking cylinder can be locked in both rotational positions (radiation beam
outlet open, radiation beam outlet closed) using fixing screws or a padlock.
Only the lower mounting plate and additionally the holes in the vertical bars
are permitted to mount the shield!
The rod source shield is available in different versions. You can find an overview
of all variants in the appendix (Technical Information).
The shield has the following functions:
• Shield radiation to a level that is non-hazardous for the operating personnel
• Locking the radiation beam outlet channel for transport and during
installation
• Protecting the integrated source capsule from mechanical damage and the
effects of the surrounding environment

Consult the radiation safety officer responsible for your company.
Ensure that no one is in the radiation beam during operation.
Longer repair and maintenance work on shields must not be carried out
with the source installed. If a removal of the source is not possible, please
contact the manufacturer.
IMPORTANT
The applicable national regulations of the country of use have to be observed.
IMPORTANT
Document the results of the tests you conducted using the check list in the
appendix. This documentation as well as the seal test certificates must be kept
during the entire life cycle of the shield.
NOTICE
Adjust the intervals of the visual inspection and the functional check to the
ambient conditions. If the ambient conditions are especially rough, the
atmosphere is corrosive and / or there is a serious threat of contamination, the
intervals should be shortened accordingly.
NOTICE
If damage affecting the secure function of the shield is detected during
handling, maintenance or regular checks, the damage must be repaired after
consultation with BERTHOLD TECHNOLOGIES GmbH & Co KG before the
system is used again. Only spare parts specified by
BERTHOLD TECHNOLOGIES GmbH & Co. KG may be used and required repair
work may be carried out exclusively by authorized persons.

6.2 Visual inspection
The visual inspection must be carried out by persons who are at least employees
with general knowledge at the following intervals:
• before initial commissioning
• with every repair that may be required
• regularly at least every six months
• before dispatch
When determining the intervals for the visual inspection, the following
conditions are to be considered:
• ambient conditions (outdoors, rain, sunlight, wind)
• operating conditions (degree of utilisation of the plant, misuse)
Performing the visual inspection:
1. Check the shield for obvious damage (dents, cracks, holes etc.) and corrosion.
2. Only before dispatch: Check if the shield is in closed position and if the
padlock as well as the transport securing device are installed.
Tip
If there is any doubt regarding the actual position of the locking mechanism:
Check the dose rate at the shield using a dose rate measuring device. If the
shield is closed, the dose rate in the direction of the beam may not be
significantly higher than at other parts of the shield.
3. If any defects are identified during visual inspection, inform the radiation
safety officer who will initiate the measures required for repairing the
defects.
For further information, please contact the manufacturer.
6.3 Leak test
Depending on the supervisory authority responsible for the area where the
source is used, regular leak tests must be carried out. These tests are to be carried
out at the discretion of the competent supervisory authority either by an
authorized expert or by the manufacturer. For this test, the corresponding source
documentation must be made available.
6 Maintenance and Repair Rod source shields LB 8300

64217BA2 Rev. 00, 10/2017
Required documents
• Inventory list of the sources to be tested including indication of previous leak
tests.
•
Source certificate containing the following information: Nuclide, activity,
procurement date, physical/chemical form, description of the enclosure and
type of sealing, resistance against mechanical and thermal influences or
classification of the source design. The source certificate is provided together
with the source.
• Information on the location, application as well as on the maximum customary
mechanical and thermal strains.
• If the source is installed in a device, a drawing is to be provided. In the
drawing, the position of the source and of all parts intended to protect the
source against external influences must be clearly indicated. Recommendations
regarding the most appropriate test method should be given, e.g. by
indicating alternative test areas. If required, recommendations should be given
on how the necessary test can be conducted without affecting the
functionality of the system or device.
Alternative test areas:
Alternative test areas are areas of a shield which will most likely be contaminated
if a source is leaking.

6.4 Checking the locking mechanism
The functional test of the locking mechanism must be carried out by a person
who is at least an employee with general knowledge. We recommend conducting
the test of the locking mechanism at the same intervals as the visual inspection if
the operating condition of the system allows.
1. Ensure that no employees are present in the direction of the radiation beam
outlet. Otherwise, these persons will be exposed to the radiation beam when
the locking mechanism is opened.
2. Open and close the locking mechanisms several times (see chapter 5) while
observing the measuring signal of the corresponding measurement system.
The locking mechanism works properly if the measured value approximately
corresponds to the maximum value when the locking mechanism is closed
(CLOSED position).
Tip
Alternatively, you can measure the dose rate in the beam path. In this case,
the dose rate in the CLOSED position must be clearly lower than in the OPEN
position. At the same time, the dose rate in the CLOSED position may not be
significantly higher than at other parts of the shield.
3. Return the locking cylinder to its starting position (OPEN position or CLOSED
position).
4. If applicable, reinstall the fixing screws and/or the padlock.
5. Immediately report any malfunction or stiffness of the locking mechanism to
the competent radiation safety officer.
