ABSTRACT
Specimens investigated within the diverse facets of nuclear forensic analysis have encompassed many types of sample matrix. The handling, collection, preservation, and storage of samples are important to the quality and ultimate interpretation of the –nal data. As in any forensic investigation, specimens must be obtained that are representative of the questioned material. Inhomogeneities in sample matrices must be considered, and for nuclear forensic specimens, such heterogeneity may be important clues to the origin and prior manipulations of the sample.
