Illegal transport of Special Nuclear Materials (SNMs) is regarded as a major terrorist risk. These SNMs are difficult to detect at border controls because their gamma emissions are typically weak, low energy, and therefore easily shielded. Since their neutron emissions are more difficult to shield, they could be more suitable to assist with detection of SNMs. However, the levels of neutron...
Sodium iodide is one of, if not the, most ubiquitous radiation detection materials deployed in the world today. It is favoured for its good light yield, good density and gamma detection efficiency, and its relative low cost of production to large (16”) crystal sizes. It is not widely recognised as one of the so-called dual-mode, or gamma-neutron, radiation detectors. That is both a disservice...
Multi-modal sensing continues to enable the development of new and improved radiation detection and imaging capabilities for nuclear security. These advancements range from increased radiological/nuclear domain awareness, to enhanced detection sensitivity and imaging performance in real-world environments. This presentation will discuss the development and application of multi-sensor systems...
