Report Tab

This screen (Fig. 140) controls the contents, destination, and some details of the output report discussed in Chapter 7.

Reporting Options

Select one or more Reporting Options by marking the checkboxes. If there is not enough information for GammaVision to generate one or more of the requested options, the software can print another option if there is enough information for it. For example, suppose a nuclide activity report is the only report option selected. If the spectrum has not been efficiency calibrated, the activities cannot be calculated. In this case, GammaVision will instead print the peak list because there is sufficient information to do that.

Output examples for all the reporting options are discussed in Chapter 7.

The ISO NORM Report

Note that analysis flags in the library editor and in the analysis parameters file,

b30winds.ini

, are treated differently between GammaVision’s standard analysis and its ISO NORM implementation. The ISO NORM report contents are discussed and illustrated in Section 7.7.11.

Library

No-MDA flag

Note that the “No MDA” flag functions differently for ISO NORM than for the standard GammaVision analysis. If an isotope flagged as “No MDA” is not detected in the sample, it is not reported in the standard GammaVision report sections unless the Directed Fit flag is turned on. However, the isotope is always reported in the ISO

NORM table.

b30winds.ini

The

b30winds.ini

file includes settings for the ISO NORM report (Section A.2.2), e.g., settings for the three probability factors,

α, β, and δ, plus a flag to report MDA if the activity is less than the CL (

In ISO NORM Table, print MDA if y < y*

). The probabilities for these factors are set by default to 0.05 for 5% error, with a range of 1.0E

!6 to 1. If the input values are outside this range, 0.05 is used. Changing the default parameters requires editing the

probability alpha

,

probability beta

, and

probability gamma

flags in the

b30winds.ini

file (see page 448 in Section A.2.2). By default, if the CL is greater than the activity, the MDA is reported. However, the

In ISO NORM Table, print MDA if y < y*

flag can be set to false so that the activity and associated uncertainty are always reported.

Following are additional

b30winds.ini

flags that operate differently for the ISO NORM calculations than for other parts of the GammaVision report:

Print MDA in Nuclide Summary

When the ISO NORM reporting option is selected, this flag (page 447) is ignored so the format of the ISO NORM table remains fixed.

Nuclide Summary MDA Text

This flag (page 448) is ignored; the “MDA” title cannot be changed to read “CL” in the ISO NORM section of the report.

Background Width for MDA

This flag (page 447) is not used in ISO NORM calculations.

Second MDA Type

This flag (page 447) is ignored because there is no second MDA in the ISO NORM table. A second MDA can still be calculated through the regular GammaVision analysis.

Allow MDA Type Change

This flag (page 443) is ignored in the ISO NORM table because there is no other

MDA type.

Uncertainty Reporting

The Confidence level multiplier shown here is used on the report only. All internal checks on peak uncertainty are done at the 1-sigma level. See Section 6 for details on the total uncertainty calculation. The uncertainty can be in Activity (e.g., 200 Bq ± 10 Bq) or Percent (e.g.,

200 Bq ± 5%). If Counting is selected, counting uncertainty will be printed. If Total is selected, both the counting and total uncertainty will be printed.

Output

When GammaVision performs an analysis, a spectrum files is automatically created with the extension of

.AN1

. In addition, the results are written to a

.UFO

file and an ASCII-format

.RPT

file that use the same base filename as the spectrum file. Use the Output section of the Report tab to send the appropriate results file to any Windows-supported Printer available to the PC, a disk File, a Program, or the optional GammaVision Report Writer. You can also choose to display the analysis results graphically onscreen, in the same form as for Analyze/Display

analysis results (Section 5.5.6).

When File is selected, you can specify a new or existing filename; click Browse... and select an existing file to overwrite with the new output data; or leave the default asterisk (*) in the filename field. In this case, the report filename will remain the spectrum filename with the extension

.RPT

.

When Program is selected, you can choose any 32-bit Windows program to be run with the report filename as an argument on the command line. The report filename sent to the program is the spectrum filename with the extension

.RPT

. The default program is Windows Notepad,

Notepad.exe

. In this case, when the analysis finishes, Notepad automatically starts, and opens the

.RPT

file. (You can also use Notepad to save the

.RPT

file to a different filename if desired or print the report.) The analysis is not complete until you close the selected program.

Instead of

Notepad.exe

, any user-written program (actually, any program that can read ORTEC

.RPT

files) can be selected here. In this case, the

.RPT

filename is used as an argument on the command line of the specified program.
