Popis:	The mutual comparison of six models for fitting the experimental breakthrough curves of 137Cs+ and 85Sr2+ transportation in the crushed rock–groundwater system is described. The models are: Clark, Thomas, modified dose–response, Yan, Yoon–Nelson and the authors’ models. These mathematical models are regarding models with continuous inlet of the radionuclides into column, and where the dependence of activity concentration on the time C = f(t) can be expressed explicitly. The use of these models should help in the more accurate determination of the retardation coefficients of radionuclides transport in crushed granite—groundwater systems in the far-field environment of disposal facilities.
