Radiostrontium and Strontium Fixation in Bones and Children's Diets. Report No. 149; RADIOESTRONCIO Y ESTRONCIO ESTABLE EN LOS HUESOS Y DIETAS DE LOS NINOS. Informe No. 149 (in Spanish)
The results of measurements of {sup 90}Sr and natural Sr in the bones of children and the food products of the corresponding diets are presented and discussed. The data show that the levels of {sup 90}Sr/Ca in the total diet are very close to that of milk for children during the first year of life. Typical incorporations in very small children, during the last three years in Argentina, were of the order of several pC of {sup 90}Sr and about a mg of natural Sr per day. Results of measurements of {sup 90}Sr in bone samples of distinct age groups, for which detailed information on the dietetic history can be obtained, are presented. The typical levels were of the orders of one pC/g Ca. Natural strontium in the bone appears to increase slowly with age. The factors of discrimination were estimated for various age groups, using a simple model and data on the diet and bones. The evaluations of {sup 90}Sr and natural Sr agree adequately and suggest that babies discriminate less between the strontiums than older children and adults. (tr-auth)
