<P>PROBLEM TO BE SOLVED: To solve such a problem that in almost conventional methods for removing radioactive contamination of soil caused by an accident of a nuclear power plant, soil contamination is performed by removing a surface layer of contaminated soil only by several centimeters and separating the removed contaminated soil from clean soil, but destination of the separated contaminated soil is not determined, and a place for storing the contaminated soil for a long period should be determined. <P>SOLUTION: The contaminated soil on the surface layer is soaked in environmental water with less radioactivity such as uncontaminated rain water or ground water of the same amount as that of contaminated rain or snow causing the radioactive contamination of soil, discharging of the dipped water to the outside or downstream is repeated to finally discharge radioactive contaminated substances of the soil to the sea through rivers. <P>COPYRIGHT: (C)2013,JPO&INPIT |
