Abstract:
The penetration of gamma rays into compartments of an aircraft carrier from two different radioisotopes was measured in 2 experiments. In 1 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 4 different deck levels. Dose distribtuion data are presented for the 2 sources used and for the different source points considered. In the 2nd experiment, a nominal 500curie collimated cobalt-60 source was exposed at a distance of roughly 100 feet from designated points to irradiate 2 general regions of the ship. Dose distributions are presented for each of 18 source positions used. Five decks were instrumented in each of the 2 general regions considered. Diagrams indicating source positions, detector positions, and hull-plating thicknesses are presented. Author
