Abstract
ABSTRACTThe new Canadian SLOWPOKE reactor has unique capabilities compared with conventional pool reactors, making multi-element trace analysis by neutron activation analysis (NAA) faster and simpler for applications such as forensic science.In this work, trace element concentration patterns obtained by NAA using the SLOWPOKE reactor have been evaluated for the characterisation of shotgun pellets, the analysis of hand samples for gunshot residues (GSR) and target to muzzle distance determinations. Little work has been reported on the characterisation of shotgun pellets, despite their frequent presence in criminal cases and the impossibility of identifying them due to the lack of rifling marks. Analysis by NAA can be performed within 3 minutes and the comparison of several samples done in 3 stages viz. qualitative examination of X-Y gamma ray spectra to eliminate obviously different samples, examination of antimony and arsenic concentrations of similar samples and finally a more conclusive characterisation...
