摘要:

A method is proposed for the chemical separation of the rare earth elements (REE) in samples with a high uranium content (0.1% to 3%) with the subsequent γ-ray irradiation in the microtron MT-25. For the quantitative determination of REE the relative analysis method was used. The method allows to analyse the massive samples (from 3 to 10 g) and provides rapidity and good sensitivity (from 10−4% for Ce to 10−5% for Eu).
