Young, T. E.

QAD-BSA, a three-dimensional, point-kernel shielding code, calculates photon dose rates and heating rates by using exponential attenuation and infinite-medium buildup factors. Calculational provisions include estimates of fast-neutron penetration using the moments method. Included geometry routines can describe complicated source and shield geometries. An internal library contains data for many frequently used structural and shielding materials; hence, the code can solve most problems with only source strengths and problem geometry as input. This code adapts especially well to problems requiring multiple sources and sources with asymmetrical geometry. In addition to being edited separately, the total interaction rates from many sources may be edited at each detector point. Calculated photon interaction rates agree closely with those obtained using another point-kernel code (QAD-P5A) and an S/sub n/ transport code (SCAMP). 2 figures, 1 table.
