Abstract:

In laboratory and preliminary field tests, a system that uses photography in the presence of a 254 nm UV illumination source has been shown useful for detection of explosives residues on surfaces. Analytes TNT, 2, 4- DNT, 2, 6-DNT, Tetryl, RDX and DPA can be detected at 10-20 microgramsq cm on concrete, transite or stainless steel. The method was not successful for wood or brick surfaces or for the analyte PETN. An alternative thermal image radiometric method of detection was unsuccessful. Keywords include Explosives Surfaces UV photography.
