7.7.4. Summary of Peaks in Range (ENV32 and NPP32 Only)

This table (Fig. 265) displays all of the peaks that were found during the analysis process with the clarifications below.

Fig. 265.

! The Library peak list option must be enabled on the Report tab for this table to be displayed.

! The peak data and nuclide activity are based a peak search run with no library peaks (i.e., a Mariscotti peak search) and no peak stripping (interference correction) applied. Any peaks identified using the Library Directed Peak Search that do not overlap those found using the Mariscotti search are also included in this table.

! The “Uncert” (uncertainty) value is 1-sigma counting uncertainty, which is directly comparable to the Peak Cutoff acceptance criterion. Only peaks with1-sigma counting uncertainty below the Peak Cutoff value are reported.

! The “Corrctn Factor” (correction factor) is the effective efficiency at the specified energy and takes into account any geometry or attenuation corrections enabled.

! The nuclide names (“Nuc”) have all non-alphanumeric characters removed for table formatting.

! All nuclides that have a photon energy within the Match Width × Calibration FWHM of a listed peak are listed as a possible source candidate along with the peak energy, branching ratio, calculated activity, and nuclide name. The specific activity for each potential nuclide candidate is calculated under the assumption that the full peak area was generated entirely by that nuclide such that all applicable correction factors (decay, efficiency, branching ratio, sample size, etc.) are applied except for any potential peak interferences.

The nuclide activity values from this table may be substituted for nuclide activity
