Book Description
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.

Book Description
Computational Methods in Reactor Shielding deals with the mathematical processes involved in how to effectively control the dangerous effect of nuclear radiation. Reactor shielding is considered an important aspect in the operation of reactor systems to ensure the safety of personnel and others that can be directly or indirectly affected. Composed of seven chapters, the book discusses ionizing radiation and how it aids in the control and containment of radioactive substances that are considered harmful to all living things. The text also outlines the necessary radiation quantities and units that are needed for a systemic control of shielding and presents an examination of the main sources of nuclear radiation. A discussion of the gamma photon cross sections and an introduction to BMIX, a computer program used in illustrating a technique in identifying the gamma ray build-up factor for a reactor shield, are added. The selection also discusses various mathematical representations and areas of shielding theory that are being used in radiation shielding. The book is of great value to those involved in the development and implementation of systems to minimize and control the dangerous and lethal effect of radiation.
