PROBLEM TO BE SOLVED: To provide a cesium removal method from radioactive cesium contaminated soil that exists in a large amount and widely, and a water system including the same.SOLUTION: Paramecium bursaria is input into soil and water suspension liquid contaminated by cesium to be cultivated, and thereby it is found that cesium can be absorbed in Paramecium bursaria to complete the present invention. By the present invention, cesium dissolved in water and insoluble cesium that strongly bonds to soil such as clay are taken in Paramecium bursaria, and effective cesium removal can be performed. Further, processing on the site of cesium contaminated soil and a water system including the same can be comparatively simply realized, so that cost and hours necessary for processing can be largely reduced and shortened comparing with a conventional method. |
