Nuclear Radiation Shielding in the Design of Hardened Structures

摘要

The transmitted dose of initial radiation is related to peak overpressure, weapon yield, and shield thickness. It is shown that the minimum expected weapon size determines the thickness of the radiation shield for a specific overpressure. A simplified method is presented for determining the protection factor for two-legged ducts. The designer can use either graphical methods or a nomogram. A mathematical analysis is included that relates protection factors to percent lethalities due to fallout radiation. (Author)
