Local fall-out and the animal food chain; Retombees locales et chaine alimentaire animale

Abstract

The local consequences of fresh fall-out, especially in the case of atmospheric nuclear explosions, are reviewed from the point of view of the internal contamination of the consumer of foodstuffs of animal origin. The edibility of foodstuffs derived from animals having grazed in the presence of fall-out is evaluated both from the wholesome and radio-toxicological points of view. The contamination level of these foodstuffs is calculated as a function of the ground fall-out, and of agronomical and ecological parameters for each radio-nuclide of the animal food chain. The internal exposure of the human consumer is calculated from this level as a function of the diet and of various parameters especially temporal. The equivalent dose to each critical organ, including the digestive tract is deduced from the burdens of each organ. From this a nutritional hygiene in the areas affected by fall-out is obtained, in relationship to the action levels fixed by the responsible authorities in exceptional circumstances. Criteria for these action levels are given as function of the food rations.

(authors) [French] Les consequences locales des retombees fraiches, notamment dans le cas d'explosions nucleaires atmospheriques, sont passees en revue en ce qui concerne les problemes de contamination interne du consommateur de denrees d'origine animale. La comestibilite des aliments provenant de betes de boucherie ayant pature sous les retombees est evaluee au double point de vue de la salubrite et de la radiotoxicologie. Le niveau de contamination de ces denrees est calcule en fonction de la retombee au sol, des parametres agronomiques et ecologiques pour chaque radioelement de la chaine alimentaire animale. La contamination interne du consommateur humain est calculee a partir de ce niveau en fonction des modalites d'ingestion et de divers parametres, notamment temporels. L'equivalent de dose au niveau de chaque organe critique, y compris le tube digestif, est deduit des charges de ces organes. L'hygiene alimentaire en zone affectee par les retombees en decoule, en relation avec les niveaux d'action fixes par les autorites responsables dans des circonstances exceptionnelles. Des criteres concernant ces niveaux d'action sont donnes et les elements de ces criteres sont calcules en fonction des rations alimentaires. (auteurs)}
