Sensing Impacts of the Fate of Trace Explosives Signatures Under Environmental Conditions

摘要

A fundamental understanding of the environmental fate and contributing mechanisms of explosives degradation is crucial for determining if emerging explosives sensor systems and concepts of operations are likely to provide effective capabilities since explosive residues vary on tactically relevant timescales. In support of trace explosives detection and sensor development, the temporal persistence and compositional evolution of trace military grade explosives were studied under both hot arid and mild temperate climate conditions as surrogate operational scenarios. The results indicate that for trace.
