Research Abstract	In this study, the impact of colloids on radionuclide migration in geosphere was investigated, by using not only laser spectroscopy and column experiments but also quantum chemical simulation technique. Especially, the migration model of radionuclides in the presence of nano-size colloids through nano-size transport paths was developed.
