BOEING-SPONSORED COMPANION STUDIES OF SHIELDING TECHNIQUES.
Abstract
The principal purpose of this final report in the companion study is to establish a set of criteria for the design of an optimum shield with respect to the weight parameter. The optimum shield may be the lightest weight shield that provides a desired level of attenuation or one that affords maximum shielding effectiveness within a specified weight limit. The study was restricted to three-layer or laminated shields of two different materials. The outer or cladding layers were of the same material and thickness. This configuration is a practical one with respect to application, and its symmetry simplifies calculations. Various combinations of ferromagnetic and nonmagnetic materials were investigated for broad spectrum attenuation. A minimum of laboratory investigation was conducted; the main portion of the study consisted of computer analyses of the postulated shields. A computer program was written to perform the parametric study of the different types of shields. Graphs summarizing the results of computer analyses are given, as well as an introductory discussion of the general laminated case or N-layer shield problem.
