This display shows any Nuclides that have been
identified in 3 columns:
TYPE – the Nuclides in the library are divided into
4 categories INDustrial, SNM (Special
Nuclear Materials), MEDical and NOR(M).
See
Appendix C
for a list of isotopes and
types.
NUCLIDE – the full name of the nuclide (isotope)
(see
Appendix C
).
S:N – the relative size of the peaks of the isotope
in SD units.
(Standard Deviation units – this gives a
good idea of the significance of the peak). For isotopes with multiple peaks the
individual peaks SDs are summed.
Left click toggles between S:N and H.L(Isotope half life).
Note: This relatively simplified display is intended to offer quick user analysis capability. For
more expert users see the further functions below.
ENTER – pressing ENTER goes to the ANALYSIS menu for further functions.
SPECTRUM STORED AS #(x) - every time an IDENTIFY analysis takes place the radiation
data (spectrum) from this analysis is stored in memory where it can be accessed with
special software for subsequent analysis as required. “Spectrum stored as #(x)” is
shown at the lower part of the screen (where x is a sequential number) to advise the
user that the spectra is being saved in memory as SPECTRUM #(x) for future
retrieval. This number (x) can be anywhere from 1 to 498 and serves to uniquely
identify the data in system memory for use during data retrieval and analysis. It is
important to keep accurate records of the
spectra origin to link the spectra to a
particular source or event. (also see
Section 5.2.3.1
– Label Spectrum).
5.2.3 ANALYSIS MENU
When Nuclide Identification is complete, pressing
ENTER goes to the main ANALYSIS menu where
further functions can be selected.
5.2.3.1 LABEL SPECTRUM
The Spectrum is stored automatically, assigning it
a unique Sample Number and tagging it with the
date and time of measurement for easy
identification. All data recorded in memory can be
downloaded to an external computer.
Each spectrum can be labeled by using the keys
supplied with the LABEL SPECTRUM page.
