This work aims to characterize features that contribute to the spectral variations that appear in gamma-ray spectra of filled uranium hexafluoride (UF6) cylinders. While the enrichment of the UF6 in a cylinder can greatly affect gamma-ray spectra at

We investigate the utility of coded aperture (CA) for roadside radiation threat detection applications. With coded aperture, information in the form of photon quantity is traded for directional information. Whether and in what scenarios this trade-of
