Detection of hard {beta} radiation in water using the Cerenkov effect; Detection des {beta} durs dans l'eau par effet Cerenkov

Abstract

The light emitted from a liquid during the passage of a particle of sufficiently high energy can be used to determine the contamination of water by {beta}-emitters. The detector based on this principle requires no special treatment of the water. Particular attention has been paid to the optical yield of the detector. However the excellent sensitivity to which this principle leads can only be attained if the background noise is considerably reduced. The electronics associated with detector make it possible to detect a contamination of 8 x 10{sup -8} {mu}c/cm{sup 3} of strontium-90 in water in about ten minutes. The apparatus presents the double advantage of having a high sensitivity and of being easy to use. Its characteristics make it possible for it to be used for the continuous control of water.

L'electronique associee au detecteur permet de reperer l'existence d'une contamination de 8 x 10{sup -8} {mu}c/cm{sup 3} de strontium-90 dans l'eau en un temps d'une dizaine de minutes. L'appareil presente l'avantage d'allier une grande sensibilite a la facilite d'emploi. Ses performances autorisent son utilisation au controle continu des eaux. (auteur)}
