Efficiency data for 11 nuclides are built into the system. Reference the Appendix for a
complete listing of the nuclides included in the CAPRAC
®
-t’s memory.
Existing efficiencies may be changed and/or new ones may be added for nuclides which do
not have any.
From Figure 6-4 Advanced Detector Setup Screen, touch the EFFICIENCIES button. Figure
6-10 Efficiencies Setup Screen will appear.

Wipe Full Spectrum Efficiency
Besides the built-in and user added nuclides, there is also a Wipe Full Spectrum Efficiency.
This is an artificial construct and corresponds to the counting rate in all the channels. The
activity for the Wipe Full Spectrum Efficiency is always reported.
This efficiency cannot be measured. The default value is 37.04%.
