Abstract:PENELOPE simulations of a Vinten ionization chamber (IC) were performed to investigate the influence of the thickness of glass-ampoules used in 222 Rn standardization. The simulation reveals a non-negligible variation of the energy deposited in the chamber gas region (which may induce a proportional variation of the measured current) when considering the transition emissions of the daughters of 222 Rn. This reinforces the idea of using a specialist container (made of metal to preserve the integrity of the co… Show more
