Analytical Method for THE DETERMINATION OF 210Po AND 230Th IN URANIUM ORE CONCENTRATES AND PLANT LIQUORS

摘要

210Po is co-precipitated with copper as the sulphide. The precipitate is separated and alpha activity due to 210Po is evaluated using an alpha scintillation counter.n210Th, present in the filtrate, is co-precipitated with lanthanum as fluoride. The precipitate is separated and alpha activity due to "°Th is also evaluated using an alpha scintillation counter.
