A method for securely and safely storing radiocontaminated waste matter and a container therefor are provided. Radiocontaminated waste matter and PSC are mixed and then retained and stored in a tetragonal cylindrical container tank 1 made of steel sheet, concrete, or PSC-containing concrete, so that the spatial gamma radiation dosage of the environment around the tank 1 becomes about the same as that of an environment or place which receives no fall-out radioactive substances. When a mixture of radiocontaminated waste matter and PSC is ashed, and the ash thus obtained is again mixed with PSC, and then loaded and stored in said container tank, the spatial gamma radiation dosage around said container tank is to be similar to that of an environment or place which receives no fall-out radioactive substances, and simultaneously both 134Cs and 137Cs are decreased, and as a result radiocontaminated waste matter can be securely and safely loaded and stored for a long-period of time. |
