 note = {In order to compare soil-to-plant transfer factors (TFs) of fallout 137Cs and those of native stable 133Cs, concentrations of these isotopes in various crops and the associated soils collected throughout Japan were determined. The results showed that TF-137Cs was 11 times higher than TF-native 133Cs for brown rice, while those values were almost the same for leafy vegetables. Possibly, fallout 137Cs would be more mobile and more easily adsorbed by plants than native 133Cs in the soil because a part of the 133Cs is in a soil structure where it is hard to replace with 137Cs. However, 137Cs and native 133Cs have reached an approximately isotopic equilibrium in the bioavailable fraction in the soils, therefore, the TF-native 133Cs can be used for long-term transfer of 137Cs in the environment.},
