Configuring and Generating the Gamma Total Reports

Background Counting Procedure

On the Gamma Total dialog, mark only the Count Background checkbox (unmark any

Gamma Total options in the left column, if they are marked). This procedure auto-generates a background report, so there is no need to mark the Write Background Report checkbox.

Select the location for the Gamma Total Report Dir. The background file will be written to this folder.

Remove any entries from the Background Spectrum, Cesium Spectrum, and Geometry

File fields, and click OK.

Count, analyze with Analyze/Entire spectrum in memory..., and save the resulting background spectrum for use in other Gamma Total analyses. This will generate a Gamma

Total background file,

B#ddmmyy.XXX

, in addition to the background

.SPC

file.

Cesium Counting Procedure

On the Gamma Total dialog, mark only the Count Cs-137 checkbox (unmark any Gamma

Total or background options, if they are marked). This selection auto-generates a maintenance report so there is no need to mark the Write Maintenance Report checkbox.

Select the location for the Gamma Total Report Dir. The maintenance file will be written to this folder.

Browse for a Background Spectrum; then select the Geometry File location and enter a new or existing geometry filename. Click OK.

Count, analyze with Analyze/Entire spectrum in memory..., and save the resulting cesium spectrum for use in Gamma Total Reporting analyses. This will generate a Gamma Total maintenance file,

.TXT

RDTCS_#.XXX

, and a geometry file with a user-assigned filename and a

extension, in addition to the cesium

.SPC

file.

Gamma Total Counting Procedure

On the Gamma Total dialog, mark the Enable Gamma Total Reporting checkbox (make sure Count Background and Count Cs-137 are unmarked). This will automatically mark the Enable Gamma Total Calculation and EDF Table Only boxes.

Select the location for the Gamma Total Report Dir.

Browse for a Background Spectrum; then select the Geometry File location and enter an existing geometry filename. Click OK.

If Write Background Report is checked, a background report will be generated. If you also specify a cesium spectrum, the K-factor to be used in the Gamma Total activity calculation will be calculated from the cesium and background spectra. If the geometry file is specified as well, then the K-factor calculated on-the-fly will be saved to the geometry file (instead of reading the K-factor from the geometry file). In addition, if the cesium spectrum is specified and Write Maintenance File is marked, a maintenance file will be generated.

Count, analyze with Analyze/Entire spectrum in memory..., and save the resulting spectrum. This will generate a Gamma Total analysis file

To count only the background within the Integration Range when performing background

QA measurements (Section 8.2.2), mark the Use Range for Background QA checkbox in the bottom section of the dialog.

Germanium Counting Procedure

On the Gamma Total dialog, mark only the Enable Germanium Reporting checkbox

(unmark any other reporting selections except, optionally, Report ISO NORM MDA On

Reports, as described below.).

Select the location for the Gamma Total Report Dir and the Germanium Report Dir.

No entries are required in the Background Spectrum, Cesium Spectrum, and Geometry

File fields. However if you want a background report generated, mark the Write Back-

ground Report field and recall a Background Spectrum. If you also specify a cesium spectrum, the K-factor to be used in the Gamma Total activity calculation will be calculated from the cesium and background spectra. If a geometry file is specified as well, then the K-factor calculated on-the-fly will be saved to the geometry file (instead of reading the K-factor from the geometry file). If you want a maintenance file generated, mark Write Maintenance File and include a cesium spectrum.
