PROBLEM TO BE SOLVED: To provide a removal method that improves the acquisition rate of a radioactive material and allows a continuous operation at low cost, and can thereby efficiently remove and process a radioactive material of a suspension (contaminated water) contaminated with the radioactive material in a short time.SOLUTION: There is provided a removal method including an agitation and separation process of flocculating and separating a radioactive material in the form of solid matter from contaminated water contaminated with the radioactive material by breaking electric bonding between the radioactive material and other materials and feeding and agitating an inorganic flocculating agent while applying vibratory energy to water molecules of the contaminated water; an air bubble mixing process of mixing fine bubbles with the contaminated water including the flocculated and separated radioactive solid matter; a flotation and separation process of floating and separating the radioactive solid matter from the contaminated water with buoyancy of the bubbles; and a recovery process of collecting and storing the floated radioactive solid matter. |
