An equation is derived for calculating the radioactivity of a source from the results of coincidence counting, taking into account the dead-time losses and accidental coincidences. The derivation is an extension of Bryant's methods [Bryant J. Int. J. Appl. Radiut. Isot. 14, 143 (1963)]. Experimental verification shows improvement over Bryant's formula. Radial. ISOL 14, 143.

The 4ฯฮฒ -ฮณ coincidence efficiency extrapolation method is the most popular for the absolute determination of radioactivity and has been successfully applied to a number of radionuclides. It requires highly experienced technicians and niggling operation to perform the radioactivity measurement via th
