...Can be used along with RadiationHelper (Beta_Gamma_MC module with Geant4 checkbox selected) but make sure that inside RadiationHelper folder there is MonteCarloPath.txt file having the first line pointing to the path of detector.exe folder (e.g. D:\\DetectorCalibration\\Build) and, if on Linux, next lines pointing to the Geant4 data.
RadiationHelper is found here: https://sourceforge.net/projects/radiationhelper/
