Calculation of conversion coefficients for anthropomorphic phantoms for criticality dosimetry

Résumé

In the event of a criticality accident, not only the total dose received by the victims must be determined but it is also crucial to evaluate the dose to the different organs. Morphology is a key parameter in the organ dose calculation. As the simulation tools can be quite long to proceed just after an accident, especially if morphology is taken into account, for all the victims, it may be very useful to have a database of conversion coefficients that allow to obtain the organ dose from the dose measured in the dosemeter for different kinds of morphology. In this paper, we present a study performed to evaluate such conversion coefficients using voxelized anthropomorphic phantoms. These coefficients take into account two crucial parameters having an impact on the dose at the organs: the orientation of the victim in the radiation field and the morphology, that is to say the body mass index of the different victims.
