【Abstract】 The diffusion behavior of ¹²⁵I,⁷⁵Se,¹³⁴Cs,and ^85,89Sr(simulating ¹²⁹I,⁷⁹Se,¹³⁷Cs and ⁹⁰Sr,respectively) in granite was studied with a specially designed diffusion cell.The sorption dynamic curves for ¹³⁴Cs and ^85,89Sr were measured.The correspond diffusion equations were solved analytically and numerically.The calculated and exprimentally observed data were compared and discussed.更多还原
