SUBSTANCE DETECTION SYSTEM ABSTRACT OF THE DISCLOSURE A system for detecting the presence of a given substance, such as an ex- plosive or a narcotic substance, within a monitored object, such as luggage, in-cludes an X-ray scanning system; a prompt gamma neutron activation analysis (PGNAA) scanning system; a conveyor for transporting a monitored object through the X-ray scanning system and the PGNAA scanning system. The X-ray scanning system provides X-ray data signals in response to X-ray scanning of the trans- ported monitored object. The neutron analysis scanning system provides neutron analysis data signals in response to PGNAA scanning of the transported monitoredobject. A data processing system processes the X-ray data signals and/or the neutron analysis data signals to provide an indication as to whether the trans- ported monitored object contains at least a predetermined amount of a given sub-stance. Both the X-ray scanning system and the PGNAA scanning system are contained within a common housing having common radiation shielding material positioned for shielding persons and objects outside the housing from both X-rays and radiation generated by the neutron analysis scanning system. The data processing system generates discriminants from the X-ray data signals and the neutron analysis data signals and conditions a neural network with the dis- criminants so that X-ray data signals and the neutron analysis data signals for monitored objects having unknown contents can be processed in accordance with the neural network to determine whether at least a predetermined amount of the given substance is contained within the monitored object.
