Radon progeny, Retrospective dosimetry, GEANT4, Diffusion in glass


Radon gas diffusion and progeny transport in air, are mechanisms to be considered in retrospective glass dosimetry.   With the aim to contribute to the understanding of the Rn progeny recoil energy role in this dosimetry methodology, we carried out a simulation employing GEANT4 code. In that, we assumed the chemical compound of the glass that is used commonly in households.  Results are compared to experimentally measured 210Bi concentration to show that the recoil energy helps the progenies incrustation, mainly for the 218,214Po alpha emitters but do not influence bismuth-210 diffusion directly….
