Аннотация:Two natural clay soils are considered as promising materials for creating safety barriers for radioactivewaste disposal. Composition indicators that affect the absorbing properties of clays have been analyzed.The absorption capacity of the soils is studied in column experiments with respect to Cs, Sr, U, Th, Ba (analogueof Ra), and Nd and Dy (analogues of Am-241 and Cm-244), which can be present in radioactive wasteof hazard classes III and IV. The experimentally derived migration parameters (effective porosity, effectivedispersion coefficient, and sorption capacity) of soils are used in predictive mathematical modeling for thecomparative assessment of the effectiveness of safety barriers made of the materials under study; the possibilityof using them for engineering safety barriers is estimated.
