I have a question about one of the extended example of GEANT4, namely example called "exrdm" that simulates radioactive decays. In principle, this example was created to show how to simulate the decays of radioactive isotopes. As a detector response one of the information extracted is the particle kinetic energy. Thus, if I would like to get emission spectra of selected radioactive isotope, I should expect to get as a result a spectrum close to the decay radiation information available for the selected isotope. In particular, I was interesting in the emission spectrum for Ba-133. This isotope should have main monoenergetic electron lines at the energies close to: 240 keV (0.33%), 267 keV (0.69%). In the brackets I indicated intensity from NUDAT2 database. However, as an output of the GEANT4 I have got a spectrum where the intencity of these two lines are simular to each othe.
Is it a real problem or it is just the lack of information in the decay tables that have been used by GEANT4 in simulation of the radioactive decays?
