ANALYTICAL METHOD FOR THE DETERMINATION OF IODINE-131 IN REACTOR FUEL PROCESSING AND EFFLUENT TREATMENT PLANT SOLUTIONS

Technical Report ·
OSTI ID:4827600
Interchange between radioactive iodine and added carrier is obtained by an oxidation reduction cycle and the iodine is then extracted as the element into carbon tetrachloride. The iodine is extracted into dilute sodium bisulphite solution and precipitated as silver iodide. The BETA -activity of the precipitate is measured with a Geiger-Mueller counier. The method is applicable to samples (3 x 10/sjup 4/ to 6 x 10/sup 5/ dpm) from the Windscale primary separation plant, uranium purification plant, and effluent treatment plant. (auth)
