 Based on the observation for O-17, for every hionization process we may consider minimum an electron released with a certain can be calculated if GEANT4 does not track the electron.
 GEANT4 does not track the electron interaction after the ionization process, so may take the information given about any free electron then fire it again to record the processes occur in the medium or study just one process as bremsstrahlung.
