An Investigation of Iodovanadinite Wasteforms for the Immobilisation of Radio-Iodine and Technetium
Ceramics, 2023 99Tc and 129I are two long-lived, highly soluble and mobile fission products that pose a long-term hazard. A proposed wasteform for the disposal of radio-iodine is iodovanadinite (Pb5(VO4)3I), an apatite-structured vanadate.
