Abstract

Sources of ionizing radiation based on the radioisotope Sr{sup 90} are widely used in apparatus and systems of automatic control and regulation of industrial processes. The technology of the preparation of sources is based on dehydration of a mixture of a radioactive solution of strontium nitrate with components such as boric anhydride, silica, and alumina. Thermic treatment of the dehydrated mixture at a high temperature produces a very mobile melt. This cools to a vitreous mass containing the required quantity of the radioisotope Sr{sup 90}. The paper gives data and discusses the results of dehydration of the system SrO - B{sub 2}O{sub 3} - SiO{sub 2} within a temperature range of 100 - 1000{sup o}C and justifies the choice of the main parameters of the technological process. It summarizes a method of mounting a vitreous preparation containing the required quantity of the radioisotope Sr{sup 90} on bases of various shapes and sizes made of steel, ceramic and other materials. The authors discuss the main parameters, ensuring that various types of sources shall be reliable and safe in operation, and give data of Sr{sup 90} sources prepared by the thermic method.

(author) [French] Les sources de rayonnements ionisants a base de strontium-90 trouvent une large application dans les appareils et les systemes de controle et de reglage automatique des procedes de production. Le procede de preparation des sources se fonde sur la deshydratation d'un melange compose d'une solution radioactive de nitrate de strontium et d'elements comme l'anhydride borique, la silice, l'alumine, etc. Le traitement thermique du melange deshydrate a haute temperature donne lieu a la formation d'une masse fondue tres mobile, dont le refroidissement fournit une masse vitreuse contenant la quantite requise du radioisotope {sup 59}Sr. Les auteurs citent les donnees et examinent Jes resultats d'une etude sur la deshydratation du systeme SrO - B{sub 2}O{sub 3} - SiO{sub 2} a des temperatures comprises entre 100 et 1000{sup o}C, et expliquent le choix des parametres de base du procede employe. Ils precisent les fondements de la methode qui consiste a monter une preparation vitreuse contenant la quantite necessaire de {sup 90}Sr, sur des supports de forme et dimensions diverses en acier, ceramique et autres matieres. Enfin, les auteurs examinent les parametres de base qui permettent l'exploitation sure et sans danger des differents types de sources, et ils donnent des renseignements sur les sources de {sup 90}Sr preparees par la methode thermique. (author) [Spanish] Las fuentes de radiaciones ionizantes basadas en el radioisotopo {sup 90}Sr se utilizan ampliamente en la industria para los dispositivos y sistemas de control y regulacion automaticos. La preparacion de las fuentes consiste en la deshidratacion de una mezcla formada por una solucion radiactiva de nitrato de estroncio, y compuestos tales como el anhidrido borico, silice, alumina, etc. Por calentamiento de la mezcla deshidratada a temperaturas elevadas, se obtiene una masa fundida muy fluida que, una vez fria, da una masa vitrea que contiene la cantidad requerida de {sup 90}Sr. Los autores presentan datos y examinan los resultados obtenidos al estudiar la deshidratacion del sistema SrO - B{sub 2}O{sub 3}- SiO{sub 2} a temperaturas comprendidas entre 100 y 1000{sup o} C; tambien explican su eleccion de los parametros basicos del proceso tecnologico. Exponen en lineas generales un metodo que consiste en montar sobre acero, materiales ceramicos u otras sustancias, de distintas formas y dimensiones, una masa vitrea que contenga la cantidad requerida de {sup 90}Sr. La memoria estudia los parametros fundamentales para lograr una explotacion regular y segura de los distintos tipos de fuente, y presenta datos relativos y fuentes de {sup 90}Sr preparadas por el metodo termico.
