Two CERN Monte Carlo codes, i.e. GEANT3.21 and GEANT4, were compared. The specific routine (sch2for), implemented in GEANT3.21 to simulate a disintegration process, and the G4RadioactiveDecay class, provided by GEANT4, were used for the computation of the full-energy-peak and total efficiencies of several radionuclides. No reference to experimental data was involved. A level of agreement better than 1% for the total efficiency and a deviation lower than 3.5% for the full-energy-peak efficiencies were found. © 2009 Elsevier Ltd.
