摘要： To provide a decontamination method and system for soil and the like for decontaminating soil such as fields and water contaminated with radioactive materials reliably and rapidly on site, performing decontamination with precision, and enhancing the efficiency of decontamination. The invention improves the decontaminated soil by adding a soil activator to the decontaminated soil, and then the improved soil is returned to the original field readily to promote the restart of farming. Further, the invention separates the radioactive materials adhering to or deposited on the soil from the soil precisely and then the radioactive materials are concentrated. The invention enables a reduction in the volume of the contaminated soil and achieves a safe treatment of the radioactive materials. An object to be decontaminated contaminated with radioactive material is introduced into an acid eluting solvent to dissolve the radioactive material. The radioactive material dissolved is concentrated and separated from the eluting solvent in the present method. The object to be decontaminated comprises contaminated soil and contaminated liquid. One or both of the contaminated soil and the contaminated liquid are collected and introduced into the eluting solvent. The radioactive materials and the object to be decontaminated dissolved in the eluting solvent are separated into solid and liquid. The decontaminated soil separated from the eluting solvent is collected. The eluting solvent used for separating the radioactive material and in which radioactive material is dissolved is concentrated.
