Proper Procedure

Update At the suggestion of reader pete tx I have added to bottom of this posting a larger photogaph of the munitions in question. The image has been flipped horizontally for ease of identification. markfromireland "Comparative bullet lead analysis was developed in the early 1960s by researchers at General Atomic (now General Activation Analysis, Incorporated, Encinitas, California) under a federal grant to develop uses for neutron activation analysis (NAA). Researchers developed procedures for analyzing such materials as gunshot primer residues, glass, paint, and bullet lead. The results of their research were published in U.S. Atomic Energy Commission Reports (Lukens et al. 1970; Lukens et al. 1970), the Journal of Radioanalytical Chemistry (Guinn 1982; Guinn et al. 1987), and the Journal of Forensic Sciences (Lukens and Guinn 1971). In one research effort, the group acquired and analyzed samples from bullet lead manufacturers. The results of these analyses confirmed that a cast billet poured from a pot of molten lead is relatively homogeneous, but that leads poured from separate molten batches are distinguishable. As a result, comparative bullet lead analysis has been adopted by laboratories and accepted by courts internationally (Andrasko et al. 1993; Blacklock and Sadler 1978; Brandone and Piancone 1984; Capannesi and Sedda 1992; Cohen et al. 1988; Desai and Parthasarathy 1983; Dufosse and Touron 1998; Gillespie and Krishnan 1969; Guy and Pate 1973; Kishi 1987; Krishnan 1973; Krishnan and Jervis 1984; Sankar Das et al. 1978; Sreenivas et al. 1978; Suzuki and Yoshiteru 1996)." In this case however none of that will be necessary. Any Questions? markfromireland
