Abstract

In the case of accidental exposure to ionising radiation, estimation of the absorbed dose in the organismis an important indicator for evaluating the biological consequences. To complete the clinical andbiological investigations, physical dosimetry methods can be used to provide an estimate of the absorbeddose and its distribution in the organism. This article describes the development of calculation tools inphysical dosimetry, in particular a numerical anthropomorphic phantom which can be adapted to eachindividual. A standard model was developed from the data available in the ICPR Publication 23. A set oftests was carried out with the model dimensions being modified to study the effect of morphology on thedose calculation. A comparison was made with another standard model used in internal dosimetry. Thesestudies highlight the parameters to be taken into account in the model, depending on whether the accidentis local or global.
