Abstract

Two radiochemical methods for the quantitative determination of tantalum and niobium, with the aid of ^182^Ta and ^95^Nb, are described. If only one of these radio‐isotopes is present, it can be determined by counting the gamma radiation emitted in a well‐cristal scintillator. The simultaneous determination of both Ta and Nb is possible by the interpretation of the entire spectrum obtained in the presence of both radioisotopes.
