| Research Abstract |
For the better understanding and modeling of the speciation of radionuclides in natural environments, it is of great importance to develop a method that capture various interactions affecting the speciation of the radionuclides. In this study, environmental behaviors of certain radionulides that are potentially important for nuclear waste disposal are evaluated by a series of methods that reflect dynamic aspects of their speciation and modeled on the basis of the obtained results.
