Shielding Computer Program 04-0 is available for computing reactor- shield weight and fast neutron and gamma ray dose rates in and around complex resctorshield assemblies. Reactor and shield geometries are described by combinations of regions formed by rotating rectangles or trapezoids about the reactor axis or by translating rectangles parallel to the reactor axis. Compositions are expressed as volume fractions for each material in the reactor- shield assembly. A cylindrical coordinate system is used to describe the location and dimensions of a volume source. Source distributions are assumed separable and may be described by cosine functions. A modification of the Albert- Welton theory of neutron attenuation is used for fast neutron dose rate calcuiations. Combination of buildup factors is used with exponential attenuation to compute gamma ray dose rates. The program requires four magnetic tape units and two frames of magnetic core memory on an IBM 704. Magnetic drum memory is
