The expert LCX Mode (Section 5.2.3.3) also displays suspected IDs, i.e., nuclides that have been tentatively
identified at too low a confidence level to list them as definitively “found.”

3.2. Identification Mode
The Identification Mode lists the radionuclides present; and displays them in one of two ways,
according to the ID Display Mode selected on the Identify setup screen (Section 5.2.3.2).

There are two ID Display Modes:
!
“ANSI” Mode — This is the default mode. Radionuclide IDs are listed on a background
color-coded according to their status as innocent (green), suspect (yellow; LCX Mode
only), or threat (red). The color background can be suppressed (Section 5.2.3.4).
!
“Classify” Mode — In this mode, the list of detected radionuclides are listed according
to category instead of radionuclide name, e.g., Medical, Industrial, Nuclear Plutonium,
Other.
Chapter 4 lists all nuclide IDs along with “ANSI” their threat/suspect/innocent status and
“Classify” category.
Figures 25 and 26 compare the same four IDs as displayed in the “ANSI” and “Classify” modes,
respectively. In each figure, the Detective-EX has found one industrial nuclide (unshielded
241
Am; innocent), and two uranium isotopes (
235
U and
238
U; threats).
In addition, this screen allows you to:
!
Pause/Continue the current identification measurement. This button has additional
functions if you are counting to a real-time preset (see Section 3.2.2).
!
Save the current spectrum and IDs (Section 3.2.3).
!
On the “Classify” display, tap to display found-nuclide reports (Section 3.2.3).
!
Tap Intense to display a continuously updating list of the 10 highest-confidence peaks
currently being detected (Section 3.2.5).
!
Display the real-time spectrum for the current data acquisition (Section 3.2.6). Note that
if the spectrum view has been disabled on the Settings dialog (Section 5.2.4.2), the
Display button is gray (inactive).
