A gamma-gamma coincidence measurement method was used for the characterization of 60 Co. A twodimensional analysis of coincident events allows the careful calculation of the number of counts, when each of the two g-rays emitted by 60 Co is in the photopeak area in each of the NaI(Tl) detectors. The
