【摘要】 应用裂变产物混合物做为示踪剂研究了¹³⁷Cs,^141,144Ce,^103,106Ru,^103,106Ru,⁹⁵Zr,⁹⁵Nb,^89,90Sr在花岗岩、凝灰岩、页岩上的吸附行为。应用批式技术测定了吸附比。核素的γ放射性是用连有SCORPIO-3000多道计算机系统的Ce（Li）探测器测量的。β放射性^89,90Sr是放化分离后在G-M计数器上测量的。结果表明:凝灰岩、页岩能强烈吸附Ce,Nb,Zr;吸附Cs居中;吸附Sr,Ru较差;花岗岩的吸附性能都差。更多还原

【Abstract】 Sorption of radionuclides ¹³⁷Cs, ^141,144Ce, ^103,106Ru,⁹⁵Zr, ⁹⁵Nb, ^89,90Sr 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 ^89,90Sr 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.更多还原
