应用裂变产物混合物做为示踪剂研究了~(137)Cs,~(141,144)Ce,~(103,106)Ru,~(103,106)Ru,~(95)Zr,~(95)Nb,~(89,90)Sr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~(89,90)Sr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。
The catalytic activity of ~ (137) Cs, ~ (141,144) Ce, ~ (103,106) Ru, ~ (103,106) Ru, ~ 95% Zr, ~ 95% Nb, ~ 89 was studied using the fission product mixture as a tracer. , 90) Sr adsorption on granite, tuff, shale. The adsorption ratio was determined using batch technology. Radioactivity of radionuclides was measured using a Ce (Li) detector connected to a SCORPIO-3000 multichannel computer system. Beta radioactive ~ (89,90) Sr is measured on a G-M counter after radiochemical separation. The results show that: tuff and shale strongly adsorb Ce, Nb and Zr; the adsorbed Cs is in the middle; the adsorbed Sr and Ru are poor; the adsorption properties of granite are poor.
