Description

The status of the program in progress at the Department of Health Protection (DPS) on some of the problems raised by the exposure of the human body to mixed radiations (neutrons, gamma-rays) is presented. The dosimetric studies, mainly carried out in collaboration with other services within the frame of the Task Group CRAC of the Directorate for Radiological Protection and Safety (DPSR), have dealt with the evaluation of doses within the body, sodium activation in the human body, and sulphur activation in the hair and nails and clothes. Radiobiological studies have been carried out on the formation of dicentric chromosomes in lymphocytes following 'in vitro' exposure of human blood, the hematological evolution, LD 50 (30 days), weight loss and pathology of delayed mortality in the rat, the excretion of urinary amino-acids and electrolytes in the rat.

Abstract (French)

Le rapport fait le point des travaux entrepris au D P S sur certains des problemes que pose l'exposition de l'organisme aux rayonnements mixtes (neutrons, gamma). Les etudes dosimetriques, dont beaucoup ont ete menees en collaboration avec d'autres services dans le cadre du Groupe de Travail CRAC de la DPSR, concernent l'evaluation des doses a l'interieur de l'organisme, l'activation du sodium du corps humain ainsi que l'activation du soufre contenu dans les phaneres et les vetements. En radiobiologie, les recherches ont porte sur la formation des chromosomes dicentriques dans les lymphocytes de sang humain expose 'in vitro', l'evolution hematologique, la dose lethale 50 (30 jours), la perte de poids et les aspects pathologiques de la mortalite differee chez le rat, l'excretion des acides aminees et des electrolytes urinaires chez le lapin.
