Abstract
Simple nitric acid leaching and alkali fusion techniques for the determinat ion of the total content of fallout Pu-239,Pu-240 in deep-sea sediment were compared. Leaching neither with boiling cone. HNO3 nor with boiling cone. HNO3+H2O2 was found to be sufficient. The sodium hydroxide fusion technique yielded reproducible analytical results and is proposed as an optimum diss olution method for quantitative determination of the total content of fallo ut Pu-239,Pu-240 in deep-sea sediment.
