Coincidence summing corrections for volume samples using the PENELOPE/penEasy Monte Carlo code

摘要

The coincidence summing correction factors estimated with penEasy, a steering program for the Monte Carlo simulation code PENELOPE, and with penEasy-eXtended, an in-house modified version of penEasy, are presented and discussed for ~(152)Eu and ~(134)Cs in volume sources. The geometries and experimental data were obtained from an intercomparison study organized by the International Committee for Radionuclide Metrology (ICRM). A significant improvement in the results calculated with PENELOPE/ penEasy was obtained when X-rays are included in the ~(152)Eu simulations.
