Disclosed is a method for rapidly treating a large amount of radioactively contaminated soil contaminated with radioactive substances such as cesium or strontium, particularly cesium 137 and strontium 90, which are artificial radionuclides, at low cost, and thereby the radioactivity in the contaminated soil. Reduce substance concentration. [Solution] Disperse and fix nanocarbon by filling radioactively-contaminated soil containing radioactive material, electrolyte and water in a container, mixing and stirring the mixture, and filling the porous material with an adsorbent of radioactive material ions The radioactive substance in the mixed solution is adsorbed and collected on the collector by bringing the collected composite into contact with a collector formed in a block shape with a water-absorbing fixing material. [Selection figure] None |
