Abstract

A new method for the absolute radioactivity measurement of radionuclides using a liquid scintillation detector comprising three photomultipliers has been described. The method does not contain any a priori model of the photomultiplier detection efficiency and uses a modified Compton Coincidence technique, therefore it has been named the Zero Model By using Coincidence Scintillation (ZoMBieS) method. Validation measurements of the activity of a ⁶³Ni source against the Triple to Double Coincidence Ratio method are presented and the results agree within their standard uncertainties.
