PRODUCTION OF CARRIER-FREE I$sup 131$ BEGINNING WITH TELLURIC ACID (in French)
The method uses telluric acid (H/sub 6/TeO/sub 6/) as a target for the production of I/sup 131/ in nuclear reactors. The experiments indicate that it is sufficient to dissolve the target in water in presence of a strong acid and to distill in order to carry over the iodine as I- and I2. The method eliminates the difficulties of target dissolution and makes it possible to obtain a very pure dlstillate after an easily performed separation. It is possible to use the sulfuric and phosphoric acids indefinitely but an excess of either acid increases the distillate acidity. The irradiations were carried out in the BR 1 reactor at Mol in a thermal flux of about 10/sup 9/ to 2 x 10/sup 12/ neutrons/ cm/su p2/sec in temperature conditions never exceeding 90 deg C. The valency-siate of the distilled iodine seems to be independent of the flux and of the integrated flux to which the target is submitted. Apparatus and production method are described. (auth)
