2.6.3 Rod source
Increased radiation dose due to open beam channel!
A too high dose of radiation may be harmful to your health.
A source may be transported only in its shielding. The shielding
must be closed during transportation and installation.
Rod source shielding
For rod sources, cylinder-shaped shieldings having the length of
the source are used which are provided with a source exit channel
(see
Fig. 2-23 ).

These shielding are placed on a suitable bracket at the measuring
site. For larger measuring ranges several parts are mounted on top
of each other. Robust construction, especially of the moving parts
of the rotating shutter, ensures reliable performance even in
heavy-duty environments.
Function failure due to damage
The detector fixture must not transfer any vibrations or heat onto
the shielding; otherwise the locking mechanism may be damaged
and the shielding effectiveness may be adversely affected.
Therefore, install the fixture on a vibration-free support or attenu-
ate possible vibrations using vibration absorbers. Prevent heat
transfer by using suitable insulating materials.
