SHIP-SHIELDING STUDIES
Abstract
The principal objectives of this project were to determine, for the types of nuclear detonations encountered during Operation Redwing, (1) the relative gamma radiation fields resulting from radioactive contaminants on a ship's weather surfaces, in the surrounding air envelope, and in the surrounding water envelope as a function of time and (2) characteristics of the interaction of gamma radiation with steel as a function of thickness and time after detonation. Shielded recording gamma-radiation detectors of known geometry were located on two YAG's to permit discrimination between the radiation fields resulting from water-borne and air-borne activities only. Unshielded detectors supplied data on the overall radiation fields on the weather decks. Recording radiation detectors inclosed in steel cylinders of various thicknesses supplied combined absorption and multiple scattering data as a function of time after detonation. (Author)
