Use of glasses as industrial dosimeters; Utilisation des verres comme dosimetres industriels

Abstract

Glasses have the property of colouring under the action of ionizing radiations. We endeavoured to specify the conditions under which the intensity of coloration can be used as a measure of the quantity of radiation to which the glass has been submitted. In the case of a glass loaded with cobalt, a study of the optical density at different wavelengths enabled us to find the factors governing the formation of coloured centres and their conservation in the glass. We give a set of calibrating curves for different values of these parameters (irradiation rate, irradiation temperature; fading time and fading temperature), enabling determination of radiation doses in the range from 10 000 to 1 000 000 rep from measured optical density.

Dans le cas d'un verre charge au cobalt, l'etude de la densite optique a differentes longueurs d'onde a mis en evidence divers facteurs dont depend la formation des centres colores et leur conservation dans le verre. En prenant comme parametres ces divers facteurs (temperature d'irradiation, intensite d'irradiation, temperature de conservation et duree de conservation) nous avons etabli des courus d'etalonnage permettant la determination de doses entre 10 000 et 1 000 000 rep d'apres la densite optique observee.
