Résumé

When a radiological accident occurred, the distribution of the dose received in the organism must be assessed within a short time. This information, which completes the clinical and biological investigations, is useful for the medical team. In this way, the physical dosimetry makes use of experimental and numerical reconstitution techniques which are generally complementary. The numerical technique consists in simulating the particles transport with a calculation code based on the Monte-Carlo method in a geometry which represents the injured person and the environment. The experimental reconstitution is performed with tissue equivalent phantoms and special dosemeters.
