چکیده انگلیسی
The transfer and distribution of 95Zr in a simulated broadbean-soil system was studied by using isotope-tracer techniques. The results showed that the 95Zr was mainly concentrated in the haulm, pod and root, and the activity concentration of 95Zr in these tissues reached the maximum in the initial stage then decreased continuously. The activity concentration of 95Zr in edible part-bean was relatively lower, which was just near to the detection limit. The 95Zr in soil was mainly (97%) deposited in surface layer soil (0-6 cm), indicating that the 95Zr absorbed by surface soil could not be moved downwards easily because of the strong adsorption. The dynamics of 95Zr concentrations in broadbean and soil were also confirmed by application of nonlinear regression method.
