摘要
In this paper results of X-ray and gamma-ray emission probabilities per decay of Cr-51 and Am-241 are presented. The measurements were carried out by means of HPGe planar and REGe spectrometers. The activity of Cr-51 and Am-241 samples was determined in a 4 pi beta-gamma coincidence counting system. The HPGe spectrometers were calibrated in a well defined geometry by means of Mn-54, Fe-55, Co-57, Ba-133, Eu-152, Ho-166m and Am-241 sources, previously standardized in a 4 pi beta-gamma coincidence system. The MCNP Monte Carlo code was used for simulation of the REGe spectrometer calibration curve, for the selected geometry, and compared with the experimental curve. The experimental results were compared with data from literature. (C) 2009 Elsevier Ltd. All rights reserved.
