The direct measurement of Co-57 activity by the sum-peak method
MetadataShow full item record
The direct measurement of the activities of Co-57 sources by application of the sum-peak method recently developed by Novkovic 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 Co-57. (C) 2012 Elsevier Ltd. All rights reserved.
