Abstract Objective ¹³⁷Cs is the one of the key nuclides in the environmental impact assessment of nuclear power plants. To understand the characteristics of adsorption and distribution of ¹³⁷Cs under different soil-water conditions,provide a basis for the evaluation.Methods the soil from the area of a certain nuclear power plant has been used to carry out experimental study about the adsorption property of ¹³⁷Cs by using Batch method.Results As the result of this study, we obtain the adsorption distribution coefficient Kd of ¹³⁷Cs in three kinds of soil, which provide instance parameter for migration patterns of ¹³⁷Cs.Conclusion The adsorption ability of the acidic soil to ¹³⁷Cs is weaker than that of the partial neutral soil. The type of water has little impact on adsorption distribution coefficient.

Key words： Batch Method ¹³⁷Cs Different Combination of Soil and Water Adsorption Distribution Coefficient K_d
