Abstract
In summary, the adsorption and physicotechnical properties of geopolymer slag-alkaline SMD materials make it possible to recommend them for radiation-shielding barriers, immobilization and storage of liquid and solid radioactive wastes, instead of the currently used technology employing ion-exchange resins and high-grade aluminate portland cement.
