Description

Liquid scintillation detectors are widely used for carrying out relative measurements of beta radioactivity in various fields. They can be used as well for absolute activity measurements, provided that an additional parameter physically related to the detector efficiency is available. In this paper, we present a method based on the use of three photomultipliers

Abstract (French)

Tres largement utilises pour les mesures relatives de radioactivite beta dans de nombreux domaines, les scintillateurs liquides permettent egalement la realisation de mesures absolues moyennant le releve d'un parametre supplementaire physiquement lie a l'efficacite reelle du detecteur. Cette methode utilisant trois photomultiplicateurs fait l'objet de la description qui suit
