Abstract
Advanced concepts in radiation detection and imaging significantly enhance the capabilities relevant for nuclear security and safety as well as in prevention and in response to nuclear and radiological attack. More recent developments in combining radiological and nuclear detection concepts with complementary sensor data and information provide yet further improved capabilities in these areas as well as in risk management and mitigation. We briefly discuss some of the new concepts and technologies that are being developed and implemented in the Berkeley Applied Nuclear Physics program. They range from micrometer resolution scale instruments that enable new means in detecting and reconstructing gamma rays to meter-scale instruments necessary to enable standoff detection capabilities. Complementary to that, contextual and environmental data are being measured and correlated with nuclear signatures and backgrounds to increase the ability to detect weak sources in the midst of spatially and temporally varying backgrounds. The concept of three-dimensional, volumetric imaging will be described as well the concept of the Nuclear Street View, both related concepts relevant for the detection and characterization of nuclear materials and associated activities. Finally, the impact of these technologies in the effective assessment of structures and radiation after a radiological or nuclear event will be discussed.
