LABORATORY STUDIES OF RADIONUCLIDES MIGRATION Ⅱ. INVESTIGATION OF SORPTION OF RADIONUCLIDES ON GEOLOGICAL MEDIA USING MIXTURE OF FISSION PRODUCTS AS A TRACER

    Graphical Abstract
    • Abstract
  • Sorption of radionuclides ~(137)Cs, ~(141,144)Ce, ~(103,106)Ru,~(95)Zr, ~(95)Nb, ~(89,90)Sr on rocksamples is investigated using a mixture of fission products as a tracer. A batch technique is used to determine the sorption ratio of nuclides ongranite, tuff and shale. The γ-activity of nuclides is counted on a Ge(Li)detecter coupled to a SCORPIO-3000 multichannel——computer system. The β-activity of ~(89,90)Sr is measuured on GM counter after radiochemical separation. The results show that rock samples of tuff and shale have very high sorptionratios for Ce, Nb, Zr, medium ratios for Cs and very low ratios for Sr and Ru,while those of granite show lower ratios for nuclides investigated.
