Select Trigger List
The “Trigger List” is the list of all of the nuclides that are currently enabled for detection
and analysis. Knowing the kind of nuclides you normally search for will help reduce
false identifications. There are five standard lists included, although your
Administrator
may choose to have different options available. These are:
ANSI – standard nuclides from ANSI N42.34.
BNC – list of common check sources and “laboratory” isotopes
MED – list of medical isotopes, normally a subset of the ANSI list
IND – list of industrial isotopes, normally a subset of the ANSI list
SNM – list of special nuclear materials, normally a subset of the ANSI list
In addition to changing lists with L
EFT
and R
IGHT
, pressing E
NTER
will display the
contents of the currently selected list. You can press E
NTER
again to return to the
menu.
Audible Count Rate
This option simply turns on and off the audible clicks that indicate the count rate. It is
important to note that if the speaker is muted (see next item), you will not hear these
clicks. Generally, you should hear the clicks as soon as you check the check box.
