- Summary
-
A theory has been developed for the attenuation of neutrons in mixtures of hydrogenous and heavy materials primarily for use in connection with shielding designs. The theory is a simplified one which assumes a neutron is essentially lost after a single collision; an equivalent cross section which includes contributions to scattering by heavy materials is left adjustable in the theory. The procedure outlined in this paper involves comparison of the theory with experimental bulk shielding results to determine the adjustable parameter. Excellent agreement--for shielding purposes--has been obtained in this way with experimentally obtained spatial flux distributions for water, iron and water, and two lead and water shields of differing composition.
