[en] Both batch experiment and column technique are used to investigate the sorption and migration behavior of radioactive ⁸⁵Sr, ¹³⁴Cs and ⁶⁰Co in loess medium. In addition, the effects of tracer concentration, pH value and temperature on distribution coefficient was also studied. It is indicated from batch experiment results that the average K_d value of sixteen samples for ⁸⁵Sr, ¹³⁴Cs and ⁶⁰Co was 82, 7.4 x 10³ and 5.4 x 10³ mL/g, respectively. Distribution coefficients were greatly affected by pH. Results indicate most of these three radionuclides remain in loess, and only a small amount of radionuclide flowed out from the loess column. In the loess column, the order of migration distance of the three radionuclides are ⁸⁵Sr > ¹³⁴Cs ≅⁶⁰Co
