MIGRATION OF RADIONUCLIDES IN SOIL UNDER A STATIC ELECTRIC-FIELD

Experimental data on migration of Cs-137, Sr-90, and Ce-144, and on de contamination of oils contaminated as;a result of the Chemobyl disaste r by applying a static electric field are reported The combined electr ochemical action on the contaminated soil, virtually completely destro ys the disperse species of radionuclides and makes them mobile. Electr ic conditions and compositions of the working fluid that provide extra ction of 95-98% Ce-144 and Sr-90 from all the soil samples and up to 9 0% Ce-137 from some samples were determined. Factors affecting the rat e and power consumption of the process were studied The electrochemica lly induced transformations of the radionuclide forms were studied.
