A decontamination system for soil and the like comprising:

• a separation vessel for receiving an object to be decontaminated contaminated with radioactive material and an acid eluting solvent, and for dissolving the radioactive material in the eluting solvent;
• a concentration tank for receiving the object to be decontaminated and the eluting solvent in which the radioactive material is dissolved, and for concentrating and separating the radioactive material;
• wherein the object to be decontaminated comprises contaminated soil and contaminated liquid, one or both of the contaminated soil and the contaminated liquid, can be introduced into the separation vessel, the separation vessel and the concentration tank are in communication with each other via a solid-liquid conduit, the solid-liquid conduit is provided with a solid-liquid separation filter for separating the soil and the eluting solvent, in which the radioactive materials is dissolved, and wherein the soil which has been separated from the eluting solvent can be collected through the filter.
