A Mathematical model for gastrointestinal tract dosimetry, and its application to adults; Modele mathematique destine a la dosimetrie du tractus gastrointestinal - application a 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 ICRP. The concentration of the radionuclide during the progression of the meal is the central concept of this model. A graph relates the MPC with the radioactive half life of the radionuclide and with any level of the gastrointestinal tract of adults.Soluble and insoluble radionuclides are considered. The case of daughter products is discussed in the Appendix. (author) [French] Une methode nouvelle permet le calcul de la dose delivree a un niveau quelconque du tractus gastrointestinal apres ingestion de substances radioactives. Elle utilise d une part la technique de calcul proposee par l'ICRP et de l'autre la notion de concentration du radionuclide au cours de la progression du repas. Un graphique simple met en relation la valeur de la concentration maximale admissible avec la periode radioactive du radionuclide et le niveau considere du tractus gastrointestinal de l'adulte. Le cas d'un radionuclide soluble et celui d'un radionuclide insoluble sont envisages. Un appendice traite le cas des filiations. (auteur)
