EXPLORATORY STUDIES ON THE PERFORMANCE OF SELECTED PAINT SYSTEMS WHEN SUBJECTED TO GAMMA RADIATION IN SIMULATED DEEP OCEAN ENVIRONMENTS.
Abstract
A nuclear radiation effects test program was performed on selected paint systems which could be used as protective coatings on radioisotopic power sources exposed in a marine environment. The paint systems were exposed to a total of 10 to the 9th power ergs/gm(C) of Co-60 gamma rays, determined from dose rate measurements by a 4 cu cm graphite wall ion chamber. The dose rate was held constant over a 3-month exposure of the paint systems simulating a deep ocean environment. No effects of pressure and a relative insensitivity to temperature were observed. No gross chemical changes were found in the simulated sea water solution. Based on a rather limited test and various instrumentation difficulties, an aluminum filled hydrocarbon and an epoxy were most resistant to the combined effects of gamma radiation and simulated deep ocean. This report describes the details of experimental design performance and data analysis. It delineates the limitations under which the above systems might be recommended for use. (Author)
