Abstract: front page image
(EN)A radioactive containment composition may be created for containing radionuclides from a radioactive material by mixing a clay mineral with water. This mixture may form an aqueous clay suspension, which in turn can be refined by filtering to remove coarse material. The aqueous clay suspension may be applied to a radioactive material, allowing the radionuclides to be exchanged with cations in the aqueous clay suspension. The resulting aqueous slurry may be collected, heated and analyzed.
(FR)L'invention concerne une composition de confinement radioactif destinée à contenir des radionucléides provenant d'un matériau radioactif, formée par mélange d'un minerai d'argile avec de l'eau. Ce mélange peut former une suspension d'argile aqueuse pouvant être raffinée par filtrage afin d'éliminer des matériaux grossiers. La suspension d'argile aqueuse peut être appliquée à un matériau radioactif de manière à échanger des radionucléides avec des cations dans la suspension d'argile aqueuse. La suspension aqueuse résultante peut être recueillie, chauffée et analysée.
