Description

  • Content Description: The gross-count tomographic gamma scanner (GC-TGS) method for assaying transuranic waste in 208-1 drums is being developed to allow NaI and other low-resolution gamma-ray detectors to be used in place of high-purity germanium (HPGe) detectors in TGS systems. It was recently shown that a logarithmic response-function technique based on the material basis set (MBS) formalism used in the TGS method allows gross spectra from NaI detectors to be used in both measuring MBS transmission corrections using external transmission sources and in applying the corrections to emission spectra to arrive at radionuclide mass estimates. In this work the authors have attempted to show that addition of the oblique scatter component can increase the accuracy of the GC-TGS measurements with both NaI and high-purity germanium detectors. This paper describes the formalism behind the GC-TGS method and the improvement achieved in the analysis by including the scatter component.
