  Conventionally, storage containers for safely storing radioactive pollutants, waste liquids, and the like are known. For example, Patent Document 1 describes a mobile radiation shielding container for safely storing and disposing of radioactive waste generated at a medical site or for storing radioactive substances. This mobile radiation shielding container is a heavy radiation shielding container formed of heavy metal such as lead in order to store a radioactive waste container or a radioactive material storage bucket. A caster is attached to the lower part of the radiation shielding container so that the radiation shielding container can be moved.

  In Patent Document 2, the outer shape of the wall portion is a hexagonal column or a substantially hexagonal column, and extends in the axial direction of the hexagonal column or the substantially hexagonal column and protrudes outward, and in the axial direction. A first concave portion extending along the inside and recessed inward, wherein the first concave portion is formed so as to be matable with the first protrusion formed in the other radioactive contaminant storage container. A storage container is disclosed. When the radioactive pollutant storage containers are stored adjacent to each other, the first projecting portion and the first concave portion of another adjacent container are fitted, so that a large amount of radioactive contaminant storage containers Can be stacked vertically.
