Dosimetry simulations based on the GEANT4 toolkit : do it yourself !
Abstract
There is an obvious recurrent need in paleodosimetric dating methods to evaluate the doses delivered in various situations, for instance, when calibrating a source, calculating attenuation factors or directly determining dose-rates , etc ... and these evaluations are never simple and numerical simulations can then be of some help. For that purpose, we developped a flexible dosimetric tool named DosiVox. This software is based on the general purpose Geant4 Monte Carlo toolkit developed by an international collaboration for simulating particle-matter interactions. This tool allows to model a large variety of complex cases relevant to luminescence and ESR dating techniques and to perform dose-rate calculations useful for age determination. The user can create a model of the sample and its environment using a graphical interface which generates a pilot text file containing all the information relevant for the simulation. No skills in C++ programming or with the Geant4 libraries are then require
