Adsorption and translocation characteristics of radionuclides in the root of tomato plant were investigated. Mature tomato plant was transplanted to culture solution containing 85Sr, 137Cs, 131I, 54Mn, 60Co and 65Zn. Immediately after transplantation, the tomato plant was cut at 10 cm above the surface of the culture solution in order to collect bleeding sap solution (Experiment-1) . Another mature tomato plant was cultured for 3 days in culture solution containing radionuclides as mentioned above and then transplanted to fresh culture solution. Bleeding sap solution was also collected in the same way as shown in Experiment-1 (Experiment-2) . Activity ratios of bleeding sap to culture solution were measured for several hours. Adsorption and removement of those radionuclides in tomato plant were summarized as following; (1) 137Cs was taken up by the root almost at the same speed as that of water and accumulated in the lowest among the six nuclides used in the experiments. (2) The concentrations of 85Sr, 54Mn and 65Zn in the bleeding sap of 3 days' uptake experiment were higher than the initial concentrations of the culture solution for several hours even after the tomato plant was transplanted to fresh culture solution. (3) 131I and 60Co were accumulated much in the root and found extremely low in the bleeding sap during the experiment, suggesting that the nuclides were absorbed on the surface of the roots and scarcely moved.
