OFR-96(2)-78 Final Report For U.S. Bureau Of Mines - Volume II: Pilot Test Plan - 1. Introduction - 1.1 Purpose

The purpose of Volume II of this study is to provide a general plan for the pilot testing of two materials which could be used to tag explosives for both pre- and postdetonation identification and of tracing techniques which would thereby aid the investigator of an unauthorized bombing or explosion in being able to determine the source and/or user of the explosives. Volume I described the planning factors by which the tagging of explosives could be implemented on a National basis. 1.2 BACKGROUND Tagging explosives at the time of manufacture with a taggant material that could survive detonation, be recovered, and provide an investigative lead has been seriously studied for several years. This concept has gained widespread support among many law enforcement groups because of the scant clues that can presently be found among bombing residue.
