2.8 General instructions on radiation protection
When working with radioactive sources, avoid any unnecessary exposure to radiation. All
unavoidable radiation exposure must be kept to a minimum. Three basic concepts apply to
achieve this:
ABC
A0016373
A Shield
B Time
C Distance
2.8.1 Shield
Ensure the best possible screening between the radiation source and yourself and all other
persons. Source containers (e.g. FQG60, FQG61, FQG62, FQG63, FQG66) and all high-
density materials (lead, iron, concrete) can be used for effective screening purposes.
2.8.2 Time
The time spent in the exposed area should be kept to a minimum.
2.8.3 Distance
Keep as far away from the radiation source as possible. The local radiation dose rate
decreases in proportion to the square of the distance from the radiation source.
2.9 Legal regulations for radiation protection
The handling of radioactive emitters is legally controlled. The radiation protection
regulations of the country in which the plant is operated are of overriding importance and
must be strictly observed. In the Federal Republic of Germany, the current versions of the
Radiation Protection Act and the Radiation Protection Directive apply. The following points
derived from this Ordinance are particularly important for radiometric measurement:
2.9.1 Handling permit
A handling permit is required by the operator of a plant that uses gamma radiation. Permit
applications are made to the local state government or the authority responsible (State
Offices for Environmental Protection, Trade Inspection Offices, etc.). The Endress+Hauser
sales organization will be happy to help you obtain the handling permit.

Source container FQG66 Basic safety instructions
Endress+Hauser 9
2.9.2 Radiation safety officer
The plant operator must appoint a radiation safety officer (RSO) who has the necessary
specialist knowledge and who is responsible for observing the Radiation Protection
Directive and all radiation protection procedures. Endress+Hauser offers training courses
in which individuals can acquire the necessary specialist knowledge.
2.9.3 Control zone
Only persons who are exposed to radiation during the course of their job and are subject to
official personal dose monitoring procedures may work in control zones (i.e. areas where
the local dose rate exceeds a specific value). The limit values for the control zone are
specified in the current Radiation Protection Ordinance applicable for your area.
The Endress+Hauser sales organization will be pleased to provide further information on
radiation protection and regulations in other countries.
2.10 Supplementary safety instructions
Please observe the safety instructions in documents SD00292F/00 (for Canada) and
SD01561F/00 (for the United States).

5.1 Installation conditions
The source container can be mounted as follows:
• On an external construction with low to zero vibration
• Directly mounted on clamping device, provided by customer, attached to the pipe
LCAUTION
Mounting the source container
‣The source container may only be mounted according to local regulations and/or the
handling permit by certified, specially trained personnel whose radiation exposure is
monitored. Ensure that this is allowed by the handling permit. All local conditions must
be taken into consideration.
‣Mount the source container in a horizontal position (i.e. with the cover pointing to the
right or left).
‣All work must be carried out as quickly as possible and as far away as possible from the
radiation source (shielding!). Suitable measures (e.g. blocking of access) must also be
taken to protect other individuals from all possible risk.
‣Mounting and removal is only permitted with the switch in the "AUS/OFF" position,
secured by the lock pin.
‣Take the weight of the source container into consideration: max. 435 kg (959.18 lb)
‣Optimum fire resistance can only be guaranteed if the FQG66 is mounted horizontally
(device standing on the device base).
‣If using the device in non-stationary plants, additional measures must be taken to
ensure the device cannot be lost, and to protect it from collision and impact.
‣Use the lifting eye and suitable lifting equipment. Consider the weight and center of
gravity of the container!
5.2 Mounting the measuring device
5.2.1 Orientation for level measurement
For continuous level measurement, the source container must be mounted at the height of,
or slightly above, the maximum level.
The radiation must be aligned exactly with the detector mounted on the opposite side. The
source container and detector should be mounted as close as possible to the product vessel
to avoid control zones.

• Gammapilot FMG60: 14 to 29 kg (30.87 to 63.95 lb)
• Gammapilot FTG20: 15.5 kg (34.18 lb)
• Source container FQG66: 435 kg (959.18 lb)
5.3 Post-installation check
 Is the device undamaged (visual inspection)?
Are the measuring point identification and labeling correct (visual inspection)?
Does the device comply with the measuring point specifications? For example:
•  ambient temperature
•  Measuring height
•  Source activity
•  Angle of emission
Are the securing screws firmly tightened?
5.3.1 Measuring the local dose rate
After mounting, the local dose rate in the vicinity of the source container and the detector
must be measured.
LCAUTION
‣Depending on the installation, radiation can also occur outside the actual radiation
emission channel through scattering. In such cases it must be shielded off by the use of
additional lead or steel shielding. Render and mark all control and exclusion areas as
prohibited for unauthorized entry.
What to do in event of empty process vessel or pipe
LCAUTION
‣If the process vessel is empty, once the unit has been correctly mounted the control
area around the empty process vessel must be measured. If necessary, this area must be
cordoned off and marked accordingly. If there is an entry into the interior space of the
process vessel, it must be sealed off and marked with a "radioactive" safety sign. Access
can only be permitted by the competent radiation safety officer after he/she has
checked all the safety precautions. The source container must be switched off for access
to be permitted. If maintenance is required in or on the product vessel, it is mandatory
to switch off the radiation. Additional shielding measures may also be required.
