Keywords:low-level radioactive waste disposal facility, sorption distribution coefficients, sorption on container wall, improvement

An improved method was investigated to determine the more realistic Kd of various radionuclides in different cementitious materials used in the construction of a disposal facility, by taking into account the sorption of radionuclides on the container wall during the experiments.
