  • Title: Improvement of a method for the sequential determination of 210Pb, 226Ra, and uranium isotopes by LSC and alpha-particle spectrometry.
    Author: Lozano JC, Blanco Rodríguez P, Vera Tomé F, Leal-Cidoncha E.
    Journal: Appl Radiat Isot; 2012 Apr; 70(4):609-11. PubMed ID: 22221465.
    Abstract:
    In a previous paper the authors proposed a sequential method for the determination of isotopes of uranium, thorium, radium, and lead from environmental samples using alpha-particle spectrometry and LSC techniques. Although the radiochemical yields were suitable when the assays were performed on synthetic samples, application to real environmental samples caused a major decrease in the radiochemical yield, especially for uranium in inorganic samples (soils). A modification of the procedure is described that overcomes this drawback.
