When collecting post-blast explosive residue examinations, it is important to ensure that all samples taken from the scene are taken with residue collection supplies that have been exposed to as little prior contamination as possible. Swabbing and sampling residue collection supplies are exposed to different environments during storage before implementation in the post-blast scene. The goal of this thesis is to provide a reference study on background levels of explosive residues on evidence collection supplies prior to their use in post-blast scenes in order to assist the forensic community and to assist in the interpretation of crime scene data. The ultimate goal is how clean is “clean.”
Thesis completed in partial fulfillment of the requirements for the Alfred University Honors Program.
