The penetration of gamma rays into compartments of an aircraft carrier from two different radioisotopes was measured in two different experiments. In one experiment, cobalt-60 and cesium-137 point isotropic sources were exposed near the hull of the ship to simulate hull contamination. Measurements of dose were made in the forward part of the ship at four different deck levels. Dose distribution data are presented for the two sources used and for the different source points considered. In the second experiment, nominal 500-curie collimated cobalt-60 source was exposed at a distance of roughly 100 feet from designated points to irradiate two general regions of the ship. Dose distributions are presented for each of 18 different source positions used. Five decks were in instrumented in each of the two general regions considered. Diagrams indicating source positions, and hull-plating thicknesses are also presented.
A symposium on Aerothermoelasticity was held to present the latest significant developments in each scientific area and engineering area that comprise the component parts of this technology. New and significant contributions were presented in four technical areas consisting of dynamic aerothermoelasticity (flutter), stability and control, thermodynamics and aerodynamics (or aerothermodynamics), and structures including material and construction concepts. Categories important and significant to each technical area are discussed state-of-the-art wise. In addition, 26 separate papers are given on items of special importance.
