Calculations of Neutron and Gamma-Ray Transport in Air-Over-Ground Geometry: Comparison with BREN and APR Experiments.
Abstract
Calculations of neutron and gamma-ray transport corresponding to the BREN and APR reactor experiments have been performed using the two-dimensional, discrete ordinates transport code DOTSAI. These calculations have been made as a test of state-of-the-art radiation transport techniques and to provide input for further analyses relevant to an ongoing program of Japanese A-bomb survivor dose reassessment. Comparisons of calculated and measured data have produced mixed results. However, it is concluded that modern calculational techniques are capable of accurately reproducing neutron and gamma-ray kerma and spectral distributions to large distances from Co-60 and fast reactor sources in an air-over-ground geometry. Keywords: Nuclear radiation, Neutrons, Gamma rays.
