Abstract : The NUCLEIDE database provides comprehensive and accurate data recommended by the Decay Data Evaluation Project (DDEP). The module NUCLEIDE++, written in C++, and designed to work in conjunction with the GEANT4 Monte Carlo toolkit has been developed to simulate the complete decay scheme for a given radionuclide by randomly selecting the decay pathways, using data from NUCLEIDE. The nuclear de-excitation of the potential daughters can also be treated in the same run. The initial energies of the electron and positron in the case of beta-emitting radionuclides are sampled from spectra calculated with the BetaShape program developed at LNE-LNHB. The aim of this work is to propose to GEANT4 users the possibility to run with the recommended NUCLEIDE data and a more detailed model. The reliability of NUCLEIDE++ is shown by comparing the coincident particles cascades to the ones obtained with PENNUC and GEANT4.
