L. Liu, S. S. Li, Z. M. Wang, Y. E. Yang, B. Li, H. Jiang, L Jiang, L. Wang, L. G. Yao, Z. M. Guo, D. Li, Z. D. Du] The migration of 90Sr in a weak loess aquifer was investigated in-situ in an Underground Research Facility. Quartz containing 90Sr, 3H and other nuclides was introduced into the aquifer with a stainless steel pipe. The local water flow field in the aquifer was monitored using a 3-dimensional sampling system. The contaminated area of the aquifer was marked out wholly with the help of a pre-installed stainless steel frame and cut into small pieces (samples) 3-dimensionally, and analyzed. The result of the -3year experiment indicated that 90Sr had normal concentration distributions in Y and Z directions. The migration rate of the mass center for 90Sr in X direction was calculated as 3.5×10-5cm/d, the distribution coefficient for 90Sr in the aquifer was calculated as 7.4×102ml/g and the diffusion coefficient for 90Sr in the aquifer in X direction was calculated as 1.3×10-11m2/s. © 2003 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Liu C.
