Absolute activity measurement of the electron-capture-based radionuclides Ce-139, I-125, Ir-192 and Zn-65 by liquid scintillation coincidence counting

Author: Van Wyngaardt, WM ; Simpson, BRS Date: Oct 2006 Four radionuclides with electron-capture-based decay schemes have been directly measured by a liquid scintillation coincidence extrapolation technique. The advantage of using (LS) counting in the 4p channel is that self-absorption does not ... Read more
Activity measurements of the high-energy pure beta-emitters Sr-89 and Y-90 by the TDCR efficiency calculation technique

Author: Simpson, BRS ; Van Wyngaardt, WM Date: Oct 2006 The absolute activities of the pure beta-emitters Sr-89 and Y-90 have been determined by a direct method, namely the triple-to-double coincidence ratio (TDCR) efficiency calculation technique. This undertaking has extended further the number ... Read more
