General information
The clamping device must be installed in such a way as to withstand the weight of the
source container and the detector (e.g. Gammapilot) under all anticipated operating
conditions (e.g. vibrations). If necessary, the customer should provide additional support
with a separate, stable, low-vibration construction.
Note the weights:
• 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.

CAUTION
‣
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
L
CAUTION
‣
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.
