PLASTIC MATERIALS IN LIGHTWEIGHT NEUTRON SHIELDS: GENERAL THEORY AND PRACTICE,
Abstract
A quick, simplified review is presented of the neutron shielding process and general criteria for determining the relative effectiveness of various shielding materials are described. Among these criteria are hydrogen density, the presence of neutron-absorbing materials, and secondary gamma emitters. A graph is presented whereby the hydrogen density of a material can be rapidly determined. Various shielding materials and fabrication techniques are reviewed, with particular attention to the highly promising cast-in-place method. A list of the major resins and other plastic materials and their relative shielding values is presented. Inspection techniques are discussed as a quality control measure to ensure void-free sections.
