Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facilities, transportation containers, and vehicles. CFD Research Corporation (CFDRC), in collaboration with Arizona State University, University of Minnesota, and Aquila, propose to develop a low-cost, passive radiation sensing system consisting of: (i) a novel microscale sensor, arrays of which can be widely dispersed, and (ii) a stand-off interrogator that probes the sensors and calculates absorbed dose. In Phase I, we investigated the performance of different components of the sensor system via modeling and experiments, analyzed the impact of several design parameters, and developed design guidelines for improved performance. Component prototypes were built and proof-of-concept demonstrations of functionality were done. In Phase II, we will focus on continued development, optimization, and integration of the components leading to a system prototype. We will investigate the performance of distributed sensor arrays via modeling, fabrication, and testing using appropriate radiation sources. Manufacturing requirements will be established for transition to commercial fabrication.
