Includes bibliographical references. Methods currently available for the accurate activity resolution of dual-label solutions of pure β-emitting radionuclides are mostly time consuming and involve much effort. The goal of this thesis was therefore to devise a simpler method to achieve the same objective. The technique developed is based on elements of two liquid scintillation counting techniques that are widely used to measure single-radionuclide solutions, namely the triple-to-double coincidence ratio (TDCR) efficiency calculation technique and the CIEMAT/NIST efficiency tracing method. Double- and triple-coincidence count rates, together with the figure-of-merit P determined from an external tracer, provide sufficient information to extract the component activities of a source in a simple manner. 2014-08-13T14:25:32Z 2014-08-13T14:25:32Z 2007 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/6284 eng application/pdf Department of Chemistry Faculty of Science University of Cape Town |
