Surrogate distributed radiological sources III: quantitative distributed source reconstructions
Jayson R. Vavrek, Jaewon Lee, Marco Salathe +4
In this third part of a multi-paper series, we present quantitative image reconstruction results from aerial measurements of eight different surrogate distributed gamma-ray sources…
Data-driven performance optimization of gamma spectrometers with many channels
Jayson R. Vavrek, Hannah S. Parrilla, Gabriel Aversano +3
In gamma spectrometers with variable spectroscopic performance across many channels (e.g., many pixels or voxels), a tradeoff exists between including data from successively worse-…
Demonstration of a new CLLBC-based gamma- and neutron-sensitive free-moving omnidirectional imaging detector
Jayson R. Vavrek, Ryan Pavlovsky, Victor Negut +4
We have developed a CLLBC-based gamma- and neutron-sensitive multi-channel omnidirectional imaging detector, suitable for handheld or vehicle-borne operation and capable of quantit…
Simulations of Sparse Static Detector Networks for City-Scale Radiological/Nuclear Detection
E. Rofors, N. Abgrall, M. S. Bandstra +6
Sparse static detector networks in urban environments can be used in efforts to detect illicit radioactive sources, such as stolen nuclear material or radioactive "dirty bombs". We…
