Figure 14 - Sample Analysis Report of
137
Cs
The initial part of the report shows the date the spectrum was acquired, the type (a manually
captured alarm), the collection time, and the same dose rate and count rate information normally
shown on the main screen.
Immediately after these, the “found nuclides” report is shown, which gives some of the most critical
information. It shows the name of any suspected nuclides, the class identification, the nuclide-
specific dose rate (in the same units as above), and the confidence in this particular identification.
The final lines in the report detail the hardware settings used in the data collection process.
Storing, Reviewing, and Retrieving Spectra
Spectra are automatically saved whenever an
Identify
process is completed. Spectra are also saved
for each background taken and for certain other operations like fine energy calibration. The Model
702i and 711i can store nearly 10,000 spectra in its “catalog.” Each stored alarm consists of a
spectrum and all the information necessary to analyze it. They are stored in a standard format
designed to comply with ANSI N42.42.
You can review and (when desired) erase these spectra using the
Spectral Data
menu.
