Resum
The presence of La-138 and Ac-227 impurities in LaBr3(Ce) scintillator crystals is a drawback for their use in environmental radiation monitoring. A method is presented to evaluate the internal La-138 activity. Firstly, an experimental set-up is prepared with the LaBr3(Ce) crystal acting as the radiation source and an HPGe detector that acquires the photon spectrum. Then, the internal background spectrum is simulated with a modified version of the PENELOPE/penEasy Monte Carlo code. The simulated...
