The analysis of radiation sensor systems used to detect and identify nuclear and radiological weapons materials requires detailed radiation transport calculations. Two basic steps are required to solve radiation detection scenario analysis (RDSA) problems. First, the radiation field produced by the source must be calculated. Second, the response that the radiation field produces in a detector must be determined. RDSA problems are characterized by complex geometries, the presence of shielding materials, and large amounts of scattering (or absorption/re-emission). In this paper, we will discuss the use of the Attila code [2] for RDSA.
