The determination count of caracteristics on a counter using the standard source 152Eu, 60Co and 137Cs. The calibration in Counter A due measurement activity source of  Europium-152 (152Eu), Cobalt-60 (60Co) and Cesium-137 (137Cs), because Cesium has one peak of energy. From the calculation on obtained efficiency the average of a sistem when using counter DIN711 is 0,0237±0,0028 and efficiency the average for each Counter A is 0,0243±0,0029. Of the value of activity between the two source measurable by both counter can be seen that counter DIN711 having results activity that were more accessible activity on certificates. To deviation of 19,71 % in counter DIN711 and 19,92 % in counter a.But counter a has deviation of 0.45 % of the measurement result of counter DIN711.Keywords: Spektrometer Nuklir, Counter, Calibration Spektrometer, Uji Banding, Calibration Linierityes, Stabilitas Test
