Source container FQG60
20 Hauser
General information
The clamping device must be installed in a way such that it can support the weight of the source
container and the Gammapilot M FMG60 under all expected operating conditions (e.g. vibrations).
If necessary, the customer should provide additional support with a separate stable, low-vibration
construction. Note weights: Gammapilot M FMG60: 14 to 29 kg (30.87 to 63.95 lbs)
Source container FQG60: max. 18 kg (39.69 lbs)
NOTICE
Mounting instructions are provided in the documentation:
SD00330F/00 and SD00331F/00.

Post-installation check Measuring the local dose rate
The local dose rate in the vicinity of the source container and the detector must be measured after
mounting the unit.
CAUTION
!
Depending on the installation, radiation can also occur outside the actual beam-emitting channel
through scattering.
‣ In such cases it must be screened by the use of additional lead or steel shielding.
‣ Render or mark all control and exclusion areas as prohibited for unauthorized entry.
Behavior in event of empty process vessel or pipe
CAUTION
!
Radiation
‣ Once the unit has been correctly mounted, the control area of the empty process vessel has to be
measured.
‣ If it is necessary, this area must be blocked off and marked. If there is an entry into the interior
space of the process vessel, it has to be closed and marked with a sign "radioactive".
‣ The entry is only allowed after checking all safety regulation by the responsible radiation
protection officer.
‣ If maintenance operations are carried out in or at the product vessel, it is mandatory to switch the
radiation OFF.
If the pipe becomes empty as a result of operational processes, the level of radiation on the detector
side can reach dangerous levels.
• In such instances, the radiation emission channel must be closed immediately for reasons of
radiation protection.
• A high local dose rate also causes the detector unit (scintillator and photomultiplier) to age quickly.
The best way to avoid such a situation is to mount a second radiometric measuring system that
monitors the radiation intensity. If high radiation levels occur, an alarm is issued and the source
container shall be switched OFF.
