ely sense the gamma rays or other indicia, an ANS system as described herein may be used to analyze the detected radiation (gamma rays or other indicia) for the purpose of determining whether explosive or other materials are present within the parcel or luggage. Advantageously, the ANS portion of such a detection system may perform its function of discriminating between parcels with and without the materials of interest simply by learning from examples, as opposed to being programmed with complex algorithms based on conventional statistical analysis techniques.
Particular features of the invention are set forth in the claims that follow.
