Installing the rod source shielding
IMPORTANT
Before installing the source shielding or the source, you have to
determine the
background (see Volume 3, chapter 7.1).
Size and position of the measuring range to be covered are deter-
mined in the projection phase for the measuring site and defined
by drawings, sketches or details in writing. For assembly, these
specifications have to be observed closely, since deviations may
cause malfunctions of the measuring system.
Fig. 2-24 shows a
standard arrangement.
Fig. 2-24 Rod Source Arrangement
The shielding must be mounted at the measuring site, so that the
top point of the rod source (size
G ) and the center of the detector
are on a horizontal line, which defines the upper point of the mea-
suring range (Max).
