Abstract
Pulsed Fast Neutron Analysis (PFNA) is a nonintrusive technique for inspecting bulk cargoes whose size may range from that of a suitcase to that of a commercial-cargo truck trailer. PFNA is based on neutron time-of-flight (TOF) measurements, and to date has been principally applied to detecting explosive and drug contraband. Here we describe a set of complementary measurements that can be supported concurrently on a single PFNA platform for (1) providing elemental signatures of chemical hazardous wastes, (2) providing matrix characterization information useful for correcting other nonintrusive measurements, (3) improving the throughput and/or sensitivity for detecting transuranic (TRU) contamination, and (4) reducing the sensitivity of TRU-assay results to systematic shielding effects.
