Gel-type decontamination agent for decontamination of radioactive contaminated surfaces using clay as a base material, its preparation method, and decontamination method using the same

摘要

The present invention relates to a field of cleaning a surface contaminated by a radioactive material, and its object is to effectively and economically remove a radioactive material present on the surface of a large-sized or locally contaminated material, a building, The present invention provides a gel-type decontamination agent for decontamination of radioactive contaminated surfaces using clay as a base material, a method for producing the same, and a decontamination method using the same.;The present invention relates to a natural clay mineral of the smacktite group as a basic substance, which contains an ion capable of exchanging with a radionuclide, and exists as a gel without separation of the phase at room temperature. When shearing force is given, the viscosity decreases, And a gel-type decontamination agent for decontaminating radioactive contaminated surfaces, wherein the remnants containing radioactivity are easily recovered.
