Summing-coincidence corrections with Geant4 in routine measurements by γ spectrometry of environmental samples
1Ionising Radiation Laboratory, Department of Fundamental Physics, University of Salamanca, 37008 Salamanca, Spain.
Abstract:
In this work, we describe a method to quantitatively evaluate true-coincidence-summing effects by making use of the Geant4 toolkit, which incorporates an emulation of the radionuclide disintegration scheme. To check the capabilities of the method, we firstly validated the simulated corrections using the ones obtained experimentally for radionuclides such as (60)Co, (152)Eu and (133)Ba. Secondly, we evaluated the effect of summing corrections of some radionuclides included in two intercomparison exercises to conclude that the results were improved when utilising the method described here.
