PURPOSE: A structure for keeping radioactive wastes is provided to block radioactivity effectively, by filling a hollow formed by cell walls with lead. CONSTITUTION: A hollow structure forms an internal space. The internal space keeps radioactive wastes. A plurality of cells (112) is partitioned by cell walls (113). A coated part (120) surrounds the outside of the hollow structure. Filler shields the radioactivity. |
