Automatic calibration of gamma-ray detectors deployed in uncontrolled environments
Marco Salathe, Nicolas Abgrall, Mark S. Bandstra +3
Radiation detectors deployed as part of a large urban network or for homeland security monitoring must maintain reliable energy calibration even when subjected to substantial varia…
Full Spectrum Modeling of In Situ Gamma-ray Detector Measurements with a Focus on Precipitation-Induced Transients
Mark S. Bandstra, James M. Ghawaly, Douglas E. Peplow +9
Gamma-ray detectors that are deployed outdoors experience increased event rates during precipitation due to the attendant increase in Rn-222 progeny at ground level. The increased…
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…
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…
Mobile Object Tracking in Panoramic Video and LiDAR for Radiological Source-Object Attribution and Improved Source Detection
M. R. Marshall, R. J. Cooper, J. C. Curtis +4
The addition of contextual sensors to mobile radiation sensors provides valuable information about radiological source encounters that can assist in adjudication of alarms. This st…
