2.6.2 Point Source 45° Cascaded
For large measurement ranges or containers with small internal
diameter, it may be necessary or beneficial to use two point source
inside the measuring range to minimize the total activity and to
improve the linearization options. Fig. 2-22 shows the appropriate
measuring geometry. The shieldings are installed below each other
in a distance of size X. For detailed information on the size X please
see the respective documentation. Depending on the size of the
measuring range, this arrangement can be realized with one or
several detectors.
