Nuclide
To set the ROI by nuclide, touch the Nuclide: field box. The Select Nuclide screen
will appear.
The screen displays a listing of nuclides stored in the calibrator’s memory (both
default and user added nuclides) – 10 at a time. Reference the Appendix for a
complete listing of the nuclides included in the CAPRAC
®
-t’s memory.
The nuclide list is in alphabetical order. User added nuclides are displayed at the top
of the list. The number of pages (or screens) will be shown in the upper right corner of
the screen indicating the length of the list. To scroll through the list, touch the DOWN
ARROW (▼) button. The next group of 10 nuclides will be displayed and the UP
ARROW (▲) button will appear allowing the user to scroll up in the list.
To cancel nuclide selection and return to Figure 10-12 Wipe General Measurement
Set Nuclide Screen, touch the CANCEL button.
To select a nuclide, do one of the following:
• Touch the Nuclide name on the list. The nuclide will become highlighted. (If
necessary, scroll the list until the desired nuclide is displayed.) Once a nuclide
is selected from the list, an ACCEPT button will appear. Touch the ACCEPT
button to choose the nuclide. Figure 10-12 Wipe General Measurement Set
Nuclide Screen will re-appear with the selected nuclide shown in the Nuclide:
field box and the keV of the main energy peak in the Region of Interest (ROI)
Start: and Region of Interest (ROI) End: field boxes.
• Touch the CLEAR SELECTED NUCLIDE button. This will cause the Nuclide:
field box to be blank (no nuclide assigned). Figure 10-12 Wipe General
Measurement Set Nuclide Screen will re-appear with the Nuclide:, Region of
Interest (ROI) Start: and Region of Interest (ROI) End: field boxes blank.
Figure 10-12 Wipe General Measurement Set Nuclide Screen depicts an ROI based
on a selected nuclide (in this case Cs137).
To abort the General Measurement, touch the HOME button. Figure 10-1 Main
Screen will appear.
To save the set ROI and continue with the General Measurement, touch the BACK
button. Figure 10-11 Wipe General Measurement Screen will re-appear with the
selected nuclide displayed in red on the screen below the COUNT TIME button
similar to that shown in Figure 10-14 General Measurement Results Screen.
