Radiochemistry Aims and scope

Abstract

Conditions of baddeleyite dissolution were examined, and an optimal method of its complete breakdown was found. A solution of 229Th tracer was prepared and used for radiochemical isolation of Th from baddeleyite. Radiochemical methds were developed for recovering the uranium and thorium fractions from a baddeleyite solution. The total chemical yield of U and Th was 71 ± 5 and 89 ± 7%, respectively.
