Abstract : Monte Carlo calculations were performed to determine the back scattering of 1.0 MeV gamma rays from concrete and their transmission through slabs of this medium. The radiation was assumed to be incidnet at various angles on a semi-infinite medium and on slabs with thicknesses of 0.55, 1.1, 2.2, and 4.4 mfp. Case histories of 100, 000 photons were followed in groups of 20,000 on an IBM 7090 digital computer for each of the six incidnet angles. Differential dose and number distributions as a function of azimuthal and polar angles are reported. (Author)
