Radio-chemical dosage of {sup 90}Sr in large volumes of drinking water; Dosage radiochimique du {sup 90}Sr sur des volumes importants d'eaux potables

Abstract

I. Principle of the method: 1. Fixing on a resin of all the cations present in the water. 2. Elution using 5 N nitric acid and precipitation of strontium as the carbonate. 3. Concentration of the strontium using the fuming nitric acid method. 4. Purification of the strontium on a resin by selective elution with ammonium citrate. 5. The strontium-90 is measured by separation at the {sup 90}Y equilibrium in the form of the oxalate which is then counted. II. Advantages of the method The concentration of the radio-activity starting from large volumes (100 l) is generally tedious but this method which makes use of a fixation on a cationic resin makes it very simple. The rest of the method consists of a series of simple chemical operations using ion-exchange on resins and coprecipitation. Finally, it is possible to dose stable strontium. (authors) [French] I.

Le strontium-90 est dose par separation a l'equilibre du {sup 90}Y sous forme d'oxalate qui est compte. II. Interet de la methode La concentration de la radioactivite a partir de volumes importants (100 l) est generalement fastidieuse, la technique proposee rend cette phase tres simple en utilisant une fixation sur resine cationique. Le reste de la technique est une suite d'operations chimiques simples a realiser, faisant appel a l'echange d'ions sur resine et a la coprecipitation. Enfin, il est possible de realiser le dosage du strontium stable. (auteurs)}
