Abstract
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.
