An ion-exchange procedure for simultaneous determination of 234U, 235U, 236U, 238U, 238Pu, 239 + 240Pu, 241Am, and 244Cm in groundwater and liquid radioactive wastes is described. The concentration and separation of U and Pu are performed on AV-17 anion exchanger in the chloride form from 9 M HCl. Am and Cm are separated from rare-earth elements by step-by-step elution from KU-2 cation-exchange resin in the NH form with a-hydroxyisobutyric acid (pH 4.75). Finally, U, Pu, Am, and Cm are determined a-spectrometrically.

    The purpose of this research is the dating of some mammoth bones from the Valley of Mexico, with the uranium-series method, which can determine the activity of the isotopic relationships 234U/238U and 230 Th/234U. Since not all samples could be dated by this method, it was necessary to apply...
