Popis: For the past two years, a cooperative nuclear forensic investigation program has been in operation in the Nuclear Reactor Laboratory at the University of Texas at Austin. An essential partner in this program has been the Crime Laboratories of the Texas Department of Public Safety, Under this program, both routine analyses of typical physical evidence samples and comprehensive survey analyses of classes of materials with forensic importance have been carried out. Both radioisotope-excited nondispersive X-ray fluorescence and multielement instrumental neutron activation analyses have been used, the first technique for screening incoming samples and performing macro-constituent analyses and the second for performing quantitative trace element analyses. Close coordination of routine analyses with the Crime Laboratories has provided supportive and complementary analyses of physical trace evidence samples for the preparation of investigative results. Carefully selected survey projects, such as the trace element characterization of safe platers and shotgun pellets described in this paper, have contributed to the development of background data available for forensic analysis in other laboratories.
