Also included is the Alarm Activity value column. Its value is affected by what is set
in the Contaminated Table Units “Activity” choices in the F5 – Configuration
screen as well as the Activity between ATP and ALS setting when determining the
value to print.
Contaminated “Print” displays Background Rate such that if Self Shield is set to 1
then “Background : # cps” is displayed. Otherwise, “Background : # x SS = #?SS
cps” is displayed (where measured background is # cps and self shield is SS). For
example, if # = 900 and SS = 1, then, it will show “Background : 900 cps”. If SS =
0.9, then, “Background : 900 x 0.9 = 810 cps” is displayed.
To customize the “Contaminated Results”, “Print” and “File & Print” choices do the
following:
1. First, file D:\MonitorProgram\CUSTOM\DLC_BEGIN.TXT is printed. This
file can be edited by user with any text editor like Windows Notepad (e.g. To
add facility banner).
2. Next, Monitor ID, Location ID and Serial Number is printed (from F3 –
Setup, F1 – Common Values).
3. Next, the following information for each enabled detector or pair sum zones is
printed. Zone, Zone Description, Bkg Rate, Net Rate, Activity, and Result.
4. Finally, file D:\MonitorProgram\CUSTOM\DLC_END.TXT is printed. This
file can be edited by user (e.g. To add signature block).
Clean & Contaminated Results Data Log
The Clean & Contaminated Results Data Log (filename RESULTS[*][*].CSV) is
similar to the Contaminated Results Data Log except that BKG, NET and UTP data
are provided for all zones for both clean and contaminated results. A final Status
column has been added to this file to record the Clean/Contaminated decision. In
Two-Step mode, the Position 1 and Position 2 results are reported on separate rows.
To customize the [Clean & Contaminated Results], [Print] and [File & Print] choices
see Contaminated Results Data Log on page 166.
Raw Background Data Log
Every background update is logged to this data log (filename RAW_BKG[*][*].CSV)
if enabled. This is intended for diagnostics and is not recommended for normal
operation since the file fills up quickly, resulting in a delay of several seconds when it
needs to be purged.
The data column headings include Gamma Bkg 1, Gamma Bkg 2, etc.
Each subsequent row of data contains the measured background collect time (sec)
followed by the total counts for each detector (there are no sum zones logged in this
