The Determination Thorium Isotopic Ratios by Radiochemical Methods

PDF Version Also Available for Download.

Description

>A sensitive analytical method was needed to determine the total thorium content and the Th/sup 2//sup 3//sup 0/ isotopic abundance in a number of uranium ore and mill talling samples available in the United States. A procedure was developed using absolute alpha counting to determine Th/sup 2//sup 3//sup 0/ and neutron activation analysis to determine Th/sup 2//sup 3//sup 2/. The method is highly specific with a sensitivity on the order of 10/sup -//sup 1//sup 0/ grams for either isotope and was found to give reliable data for the various sample types of interest. (auth)
