Note:
Section 5.2.1
covers instrument behavior if IDENTIFY is started from the MAIN MENU.
Section 5.2.2
covers the ANALYSIS Mode of operation.
5.2.1 IDENTIFY DISPLAY
Once the location of the source is detected the
user can attempt to identify the type of source
by switching to the IDENTIFY function. The
IDENTIFY function is activated by pressing
ENTER, displaying a new screen:
Note: To obtain good results, position the Syclone at
the highest point of radioactivity found by the
SEARCH function. Keep the Syclone as stable
as possible during sampling to get a good result.
IDENTIFY
display (Information Line):
SCANNING!
– the function currently activated.
Alternative displays in information line are:
MOVE CLOSER
– means that the
signal is very weak so if
possible the user should move the unit closer to the suspect source of radiation. In
many cases this is impossible so no action need be taken, but if possible move the
unit closer until the display shows OK.
MOVE AWAY
– means that the signal
is stronger than is necessary
to take a proper sample. Correct action is to back away until the display shows
SCANNING!.
Labels are:
RANGE –
9-3265keV shows that the full 3MeV spectrum is displayed.
DEAD TIME - shows the Sodium-Iodide dead time as a %.
CURSOR – the cursor position data is displayed in keV.
TIME –
shows sample progress (10 secs currently).
ROI 4 –
This is the Region of Interest (4) collected by the sodium iodide (NaI) detector.
The current cursor position is in ROI 4.
NEUTRON – Shows that measurement is for Neutrons. The example shows 67 counts
(Counts of neutrons detected).
CURSOR – the cursor position data is displayed in counts.
SET –
shows the preset sample time of 20 seconds.
5.2.2 ANALYSIS DISPLAY
When the sample time terminates, the Nuclide Identification function is automatically
activated, displaying the Nuclide Identify Page.
