    摘要： [Problem to be Solved]
    To provide a decontamination method and system for soil and the like for decontaminating soil of, for example, fields, and water contaminated with radioactive materials reliably and rapidly on site, aiming to perform decontamination with precision and improved efficiency. According to the present invention, the decontaminated soil is improved by adding soil activators, and then the improved soil is returned to the original field readily to promote the restart of farming. Further, according to the present invention, the radioactive materials adhering to or deposited on the soil are separated from the soil and then concentrated precisely. According to the invention, a reduction in the volume of the contaminated soil and a safe treatment of the radioactive materials are achieved. Further, according to the invention, decontamination of radioactive cesium and tritium is achieved, thereby relieving anxiety of internal exposure to the radiation of tritium. Further, the decontamination apparatus can be disposed of efficiently and safely.
    [Solving Means]
    An object to be decontaminated contaminated with radioactive material is introduced into the eluting solvent 49 and dissolved, and the radioactive material is separated from the eluting solvent 49. The object to be decontaminated includes the contaminated soil 17 and the contaminated water 4. One or both of them are collected and introduced into the eluting solvent 49. The radioactive materials dissolved into the eluting solvent 49 and the object area to be decontaminated are separated into solid and liquid. The soil 17a 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 37 containing contaminated water are introduced into the electrolysis tank 13 and electrolyzed. The decontamination method for soil and the like includes depositing metal ions such as the radioactive materials on the cathode 31. Hydrogen containing tritium generated in electrolysis is collected in the electrolysis tank 13. The hydrogen is moved to the outside of the electrolysis tank 13 and trapped.
