PCT No. PCT/FR95/01454 Sec. 371 Date Oct. 24, 1996 Sec. 102(e) Date Oct. 24, 1996 PCT Filed Nov. 6, 1995 PCT Pub. No. WO96/18126 PCT Pub. Date Jul. 13, 1996The invention relates to the conditioning or packaging of radioactive iodine, particularly iodine 129, using an apatite as the confinement matrix. Having the iodine, said apatite corresponds to the formula: M10(XO4)6-6x(PO4)6xI2(I)in which M represents Cd or Pb, X represents V or As, I is the radioactive iodine to be conditioned and x is such that 0</=x<1. This iodoapatite (1) can be surrounded by an apatite (3) not containing iodine serving as a physical barrier. The iodoapatite can be obtained from a solid compound of the iodine, e.g. an iodide such as silver iodide or lead iodide, by reaction with a compound of formula: M3(XO4)2-2x(PO4)2x(II)or M10(XO4)6-6x(PO4)6xY2(III)in which M, X and x are as defined hereinbefore and Y can represent OH, F, Cl or O+E,fra 1/2+EE .
