    摘要： A concrete pit containing radioactive waste is surrounded by a low diffusion layer of cement-based material, which in turn, is surrounded by a low water permeability layer of sodium-type bentonite and the leaching out of calcium ions from the low water permeability layer is inhibited by mixing sodium bicarbonate or sodium carbonate with the sodium-type bentonite/sand mixture of the low water-permeability layer so that leached calcium ions form a barrier layer having calcium carbonate as the main component in the vicinity of the interface between the layers.
