摘要

This work is concerned with the theoretical calculation of both the total mass attenuation coefficients (μ/ρ) for gamma rays and the effective removal cross-sections (Σ_R) for fast neu- trons. Calculations were carried out for four types of concrete of different densities namely (1) dolomite-sand ρ = 2.5 g. Cm~-3, (2) barite-barite ρ = 3.49 g. Cm~-3, (3) magnetite-limonite ρ = 3.6 g. cm~-3 and (4) ilmenite - ilmenite ρ = 3.69 g cm~-3.
