Paper Abstract

A non-intrusive, passive technique for the inspection of large cargo containers for plant contraband was investigated. The method is based on the detection of naturally occurring K-40 gamma-ray emissions. The results of preliminary dynamic field tests conducted at a Canada-US border-crossing using plastic and sodium iodide detectors are reported. Speed normalized results obtained from a wide range of cargo trucks, including controls carrying known amounts of a K-40 simulant, were used in discerning the presence or absence of K-40 emissions. A multi-component feature analysis method for the classification of cargo contents was investigated.
