A new strategy for the confinement of iodine has been developed: it consists in incorporating iodate anions (IO3−) into hydroxyapatite (Ca10(PO4)6(OH)2, HA). The iodate-substituted HA was synthesized by precipitation, and characterized detail. Its thermal stability resistance to leaching were then evaluated, revealing promising properties view radioactive applications.
