摘要：A portal trace detection apparatus is provided for detecting minute particles ofinterest, such as traces of narcotics, explosives and other contraband. The apparatus
includes a portal through which a human suspect will pass. A detection apparatus isdisposed at least partly in the ceiling of the portal, and hence above the human subject inthe portal. Particles of interest will be entrained in the human thermal plume that existsin the boundary adjacent the suspect, and will flow upwardly from the suspect to thedetection apparatus in the ceiling of the portal. The ceiling is coated with an anti-staticmaterial so that particles are more likely to flow towards the detector and less likely tobe affixed electrostatically to the ceiling.
