Abstract
In this study, a simple procedure for the determination of natural uranium, thorium and radium isotopes in water and soil samples by alpha spectroscopy is described. This procedure allows a sequential extraction polonium, uranium, thorium and radium radionuclides from the same sample in two to three days. It was tested and validated with the analysis of certified reference materials from the IAEA.
Kurzfassung
In dieser Untersuchung wird ein einfaches Verfahren zur Bestimmung natürlicher Uran, Thorium- und Radiumisotope in Wasser- und Bodenproben mit Hilfe der Alphaspektrometrie vorgestellt. Dieses Verfahren erlaubt eine sequentielle Extraktion von Polonium-, Uran-, Thorium- and Radiumisotopen aus der gleichen Probe in zwei bis drei Tagen. Es wurde geprüft und validiert durch eine Analyse zertifizierter IAEA Referenzmaterialien.
