Abstract
Sandia National Laboratories evaluates and develops new techniques and technologies to ensure the integrity of special nuclear material (SNM) against potential insider threats. We have evaluated several types of sensor technologies and subsystems to monitor and/or track materials and personnel. This past year's effort has been directed at characterizing commercial developments that meet the Department of Energy's (DOE) needs in some of these areas. Some of these evaluations are complete and some are still in progress. This paper discusses our work with infrared light (ER), radio frequency (RF), and RF proximity technologies. After these technologies are judged to be applicable to DOE's needs, we incorporate them into the generic, real time, personnel tracking and material monitoring system.
