Immobilization of~(99)T_c in low-temperature phosphate ceramic waste forms

摘要

Radionuclides such as ~(99)T_c are by-products of fission reactions in high-level wastes. Technetium poses a serious environmental threat because it is easily oxidized into its highly leachable pertechnetate form. Magnesium potassium phosphate ceramics have been developed to treat ~(99)T_c that has been separated and eluted from simulated high-level tank wastes by sorption processes.
