Analysis of the Frequency and Detectability of Objects Resembling Nuclear/Radiological Threats in Commercial Cargo
Brian S. Henderson
The threat of smuggled nuclear/radiological weapons and material in commercial containerized cargo remains a significant threat to global security more than a decade after the enac…
High-accuracy Geant4 simulation and semi-analytical modeling of nuclear resonance fluorescence
Jayson R Vavrek, Brian S Henderson, Areg Danagoulian
Nuclear resonance fluorescence (NRF) is a photonuclear interaction that enables highly isotope-specific measurements in both pure and applied physics scenarios. High-accuracy desig…
Validation of Geant4's G4NRF module against nuclear resonance fluorescence data from U and Al
Jayson R Vavrek, Brian S Henderson, Areg Danagoulian
G4NRF is a simulation module for modeling nuclear resonance fluorescence (NRF) interactions in the Geant4 framework. In this work, we validate G4NRF against both absolute and relat…
Experimental Demonstration of Multiple Monoenergetic Gamma Radiography for Effective Atomic Number Identification in Cargo Inspection
Brian S. Henderson, Hin Y. Lee, Thomas D. MacDonald +2
The smuggling of special nuclear materials (SNM) through international borders could enable nuclear terrorism and constitutes a significant threat to global security. This paper pr…
