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