Preparation of 137Cs Pollucite Source Core

Pages 404-408 | Published online: 22 Jul 2008
 

Abstract

A method for the preparation of 137Cs ceramic pollucite source core is presented. The amount of cesium introduced into formed zeolite pellets is 30%wt. The transformation of zeolite loaded with cesium into the pollucite was investigated thermoanalytically. The structure of the obtained pollucite was determined by the X-ray diffraction method. The leachability and vaporization of cesium from the obtained ceramics was investigated.

Es wird eine Methode zur Herstellung einer keramischen 137Cs Polluzil-Strahlenquelle beschrieben. Die Menge an eingetragenem Caesium in die gebildeten Zeolithpellets betragt 30 Gew.−% und die Umwandlung des Cs-beladenen Zeotiths in Polluzit wurde thermoanalytisch verfolgt. Die Struktur des erhaltenen Polluzits wurde mit Hilfe der Röntgenbeugungs-methode bestimmt. Die Auslaugbarkeit und die Verdampfung des Caesiums aus den erhaltenen Keramiken wurde ebenfalls untersucht.
