This presentation will go through some of the challenges to performing quantitative non-destructive gamma-ray spectrometry analysis for nuclear forensics as well as our attempts to overcome these challenges.  Some of these challenges include unusual matrices and geometries of the samples and the lack of standards available.  A brief comparison of several different approaches to determining quantitative results for gamma spectrometry will be discussed; particularly, the traditional relative method and computational methods that have been developed, such as the FRAM and SNAP codes.  Lastly, examples of how these different approaches are being utilized in the Actinide Analytical Chemistry group at Los Alamos National Laboratory will be demonstrated, along with a comparison of the results and uncertainties for those analyses.
