PHYSICAL DOSIMETRY TECHNIQUES USED FOR RA DIOLOGICAL ACCIDENT RECONSTITUTION

When a radiological accident occurred, the distribution of the dose re ceived in the organism must be assessed within a short time. This info rmation, which completes the clinical and biological investigations, i s useful for the medical team. In this way, the physical dosimetry mak es use of experimental and numerical reconstitution techniques which a re generally complementary. The numerical technique consists in simula ting the particles transport with a calculation code based on the Mont e-Carlo method in a geometry which represents the injured person and t he environment. The experimental reconstitution is performed with tiss ue equivalent phantoms and special dosemeters.
