DCTDOS: Neutron and Gamma Penetration in Composite Duct Systems

摘要

The paper describes computer methods for estimating neutron and gamma ray fluence rate, dose, and even spectral features due to penetration through a series of duct segments. The procedure links together data for individual segments -- straight sections and bends -- in arbitrary combinations; and the resulting composite can include computations for a room at the end, if there is one. This particular method was developed for rapid estimates in the protection problems against nuclear weapons, but the concepts which are employed are more broadly applicable.
