Rapid Neutron Activation Analysis for Gunshot Residue Determination
A recent review of neutron activation analysis (NAA) applications in forensic science by Guinn has again focused attention on the utility of barium and antimony determinations on residues removed from the hands as indication of recent gun firing by the individual. This method has been well established and is in routine use by state, local, and federal law enforcement groups in the United States and by governmental agencies in other countries. Increasing use of this technique has made reduction in sample analysis time imperative.
