Résumé

In the event of a radiological accident caused by an external source, estimating the dose distribution in the victim's body is a relevant indicator in assessing biological damage from this exposure. This dose distribution can be assessed by physical dosimetric reconstruction methods. Physical dosimetric reconstruction can be achieved using experimental or numerical techniques. This article presents the laboratory-developed SESAME tool specific to dosimetric reconstruction of a radiological accident through numerical simulations, which combines voxel geometry and the radiation-material interaction MCNP(X) Monte Carlo computer code. The experimental validation of the tool in photonic field and its application to a radiological accident in Chile in December 2005 are also described.
