Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effectiveness for deployment of sensor networks for efficient radiation detection across large storage facilities, transportation containers, and vehicles. CFD Research Corporation (CFDRC), in collaboration with Arizona State University (ASU) and a leading manufacturer of radiation dosimeters, propose to develop a low-cost, passive radiation sensing system consisting of: (i) a novel microscale sensor architecture, 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 will perform physics-based modeling of system components to derive design guidelines for improved performance. Unit structures will be built using micro fabrication techniques, and proof-of-concept devices demonstrated by detection of total dose. In Phase II, we will optimize component designs and investigate the performance of a distributed sensor array based on modeling, advanced signal processing, and fabrication/testing. Testing and evaluation of the improved sensor technology will be accomplished through validation cases selected in consultation with DTRA.
