title: The direct measurement of 57Co activity by the sum-peak method.
abstract: The direct measurement of the activities of (57)Co sources by application of the sum-peak method recently developed by Novković et al., is described in this paper. The comprehensive assessment of the uncertainty budget of the activity of the measured sources has been analyzed. The presented method is successfully tested using an HPGe spectrometer with efficiencies of 50%. The accuracy of this method is confirmed to be comparable with the commonly used methods of the activity measurement of (57)Co.
