| Abstract: | Methods of capturing and immobilizing radioactive nuclei with metal
fluorite-based inorganic materials are described. For example, a method
of capturing and immobilizing radioactive nuclei includes flowing a gas
stream through an exhaust apparatus. The exhaust apparatus includes a
metal fluorite-based inorganic material. The gas stream includes a
radioactive species. The radioactive species is removed from the gas
stream by adsorbing the radioactive species to the metal fluorite-based
inorganic material of the exhaust apparatus. |
