Author:Van Wyngaardt, WM; Simpson, BRSDate:01 Aug 2006A simple counting technique to measure mixtures of two pure beta-emitting radionuclides is described. The method is based on elements of two liquid scintillation techniques that are widely used to measure single-radionuclide solutions, namely ...Read more
Author:Simpson, BRS; Morris, WMDate:Feb 2004The activity of the pure beta-emitter phosphorus-33 (P-33) has been directly determined by the triple-to-double coincidence ratio (TDCR) efficiency calculation technique, thus extending the number of radionuclides that have been standardized ...Read more
