Abstract:
During the EMRP JRP MetroMETAL project a detector image of an aged HPGe gamma-ray detector was created for MC efficiency calculation. Using the nominal construction parameters of the detector, the simulation showed unacceptably high deviations from the assured activity values. This paper describes an optimisation of a virtual detector to obtain better results using limited resources and offers comparisons of efficiency values of point and voluminous sources calculated by LABSOCS® and PENELOPE 2011.
