| 内容記述 | Cesium-137 (137Cs) is a radionuclide which can be released from nuclear facilities to the terrestrial environment; therefore, its transfer from soil to plant is of great interest for environmental safety assessments. It is necessary to take into account the form in which Cs exists in the soil because Cs can be fixed in clay minerals and the fixed Cs is not easily used by plants. Since a stable isotope 133Cs is present in the environment, plant uptake of 137Cs should be the same as that of 133Cs. Moreover, Cs uptake by plant is influenced by potassium (K), which is an essential element, for two major reasons; K and Cs have similar chemical characteristics, and a large amount of K is present in agricultural fields due to application of K fertilizer. In this study, we discuss relationships among 137Cs, 133Cs, and K in plant uptake with especial consideration of the assumptions of two fractions in soil, that is, exchangeable (plant-available) and fixed (plant-unavailable) fractions. | |||||
