Time-Dependent Neutron and Secondary Gamma-Ray Transport in Infinite Air and in Air Over Ground
Abstract
The general description of the radiation field was determined for several neutron source energies in infinite air and in an air-over-ground geometry for source heights of 50 and 1125 feet. The effect on dose of source height and detector height and the effect of the ground on energy, angular, and time dependence is discussed for both fission and 12.2- to 15-MeV neutron sources. The satisfactory agreement of calculations with experimental results from operations BREN and HENRE and the agreement between Monte Carlo and discrete ordinates results lend confidence to the cross sections used and the computational techniques.
