A prototype of radioactive waste drum monitor by non-destructive assays using gamma spectrometry

摘要

In this work, segmented gamma scanning and the gamma emission tomography were used to locate unknown sources in a radioactive waste drum. The simulated detector response function and full energy peak efficiency are compared to corresponding experimental data and show about 53% difference for an energy ranging from 81 keV to 1332.5 keV for point sources. Computation of the corresponding activity is in good agreement with the true values. (C) 2015 Elsevier Ltd. All rights reserved.
