| 内容記述 | Technetium-99 (99Tc) is produced from the fissions of 235U and 239Pu with relatively high yields (about 6%) and it has a long half-life (2.11 x 10^5 y). Understanding its fate in the environment is important because of the potential long-term radiological consequences of releases of the radionuclide into the environment. The radionuclide is known to be concentrated in plants, and its uptake occurs not only with water mass flow or active nutrient uptake, but also with uptake of nutrient cations such as K+. Interestingly, the uptake behavior of Tc and Re were the same so that it was implied that Re can be used a chemical analogue of Tc in plant uptake. On the other hand, Re might affect Tc uptake when elevated amounts of Re were applied compared to Tc content. The purpose of this study to clarify the effect Re at high concentrations on Tc transfer from nutrient solution through radish plants as well as Re toxic concentration levels to radish plants instead of using Tc. | |||||
