Une méthode nouvelle permet le calcul de la dose délivrée à un niveau quelconque du tractus gastro-intestinal après ingestion de substances radioactives. Elle utilise d’une part la technique de calcul proposée par la C.I.P.R. et de l’autre la notion de concentration du radionucléide au cours de la progression du repas.
Un graphique simple met en relation la valeur de la concentration maximale admissible avec la période radioactive du radionucléide et le niveau considéré du tractus gastro-intestinal de l’adulte.
Abstract
A new method is proposed for the computation of the dose delivered to any level of the gastrointestinal tract after ingestion of radioactive substances. The same method is used as that proposed by I.C.R.P. The concentration of the radionuclide during the progression of the meal is the central concept of this model.
A graph relates the M.P.C. with the radioactive half-life of the radionuclide and with any level of the gastrointestinal tract of adults.
