An object to be decontaminated contaminated with radioactive material, e.g., contaminated soil or water, is introduced into eluting solvent and dissolved, and the radioactive material is separated from the object to be contaminated by elution of the radioactive material into the eluting solvent. The eluting solvent containing the radioactive materials dissolved therein and the object to be decontaminated are separated into solid and liquid. The soil after solid-liquid separation and from which the radioactive material is removed is collected, and the eluting solvent after solid-liquid separation and a separated liquid containing contaminated water are introduced into an electrolysis tank and electrolyzed. Metal ions such as those of the radioactive materials are deposited on the cathode in the electrolysis tank. Hydrogen containing tritium generated in electrolysis is collected in the electrolysis tank. The hydrogen is moved to the outside of the electrolysis tank and trapped.

Abrégé

The purpose of the present invention is to provide a decontamination system for rapidly and reliably decontaminating soil and water of an agricultural field or the like that has been contaminated by a radioactive substance, obtaining fine decontamination and enhanced decontamination efficiency, adding a soil activator to decontaminated soil to improve the soil, rapidly returning the improved soil to the originating field to facilitate resumption of farming, and meanwhile finely separating and concentrating radioactive substances deposited on the soil from the soil and ensuring reduced volume of contaminated soil and safe processing of the radioactive substances. A decontamination object (2) contaminated by a radioactive substance is introduced to an acidic eluting solvent (56) and eluted out. The decontamination object contains contaminated soil (17) and a contaminated liquid. The contaminated soil (17), the contaminated liquid, or both in the decontamination object are collected and introduced into the eluting solvent (56). The decontamination object (2, 17) and the radioactive substances eluted into the eluting solvent (56) are subjected to solid-liquid separation. The decontaminated soil is separated from the eluting solvent (56) and recovered. The eluting solvent (56) in which the radioactive substances have been eluted out is separated from the soil and concentrated.
