Abstract
(EN)
Method of pakaging radioactive iodine, in particular, iodine 129, using apatite as the containment matrix. Said iodine-fixing apatite is based on formula (I): M10 (XO4)6-6x (PO4)6x I2, wherein M is Cd or Pb, X is V or As, I is radioactive iodine to be packaged and x is such that O « x < 1. Said iodopatite, which can be surrounded by a physical barrier of non-iodized-apatite (3), is obtainable from a solid iodine compound, for exemple, an iodide such as silver iodide or lead iodide, by reaction with a compound of formula (II): M3 (XO4)2-2x (PO4)2x, or (III): M10 (XO4)6-6x(PO4)6x Y2, wherein M, X and x are defined above and Y is OH, F, C1 or O1/2.
(FR)
L'invention concerne le conditionnement d'iode radioactif, en particulier d'iode 129, utilisant une apatite comme matrice de confinement. Cette apatite ayant fixé l'iode répond à la formule (I): M10 (XO4)6-6x (PO4)6x I2, dans laquelle M représente Cd ou Pb, X représente V ou As, I est l'iode radioactif à conditionner et x est tel que O « x < 1. Cette iodoapatite (1) peut être entourée par une apatite non iodée (3) jouant le rôle de barrière physique. L'iodoapatite peut être obtenue à partir d'un composé solide de l'iode, par exemple un iodure comme l'iodure d'argent ou l'iodure de plomb, par réaction avec un composé de formule (II): M3 (XO4)2-2x (PO4)2x, ou (III) M10 (XO4)6-6x(PO4)6x Y2 dans lesquelles M, X et x sont tels que définis ci-dessus, et Y peut représenter OH, F, C1 ou O1/2.
