In radioactivity processing facilities such as nuclear reactors, each processing chamber is hermetically divided by a thick shielding wall. An example of this is shown in the side sectional view of FIG. As shown in the figure, each processing chamber A, B is divided by a shielding wall 1, and the ceiling wall of each processing chamber A, B is provided with openings 2A, 2B. Radioactive substances 10 in radioactivity processing equipment 4A, 4B installed in processing chambers A, B are taken in and out through these openings 2A, 2B. This opening 2A, 2
B is always plugged with plugs 3A and 3B that fit thereto to prevent leakage of radioactivity to the outside. Note that this plug serves as a shielding door. In addition, in order to prevent exposure to radiation from the radioactive materials 10 taken out from the processing chambers A and B, an amber zone (intermediate chamber) C is provided at the top of the processing chambers A and B with a shielding wall 5.

However, with the conventional shielding door structure as described above, when moving radioactive materials, the plug that seals the opening must be removed and fitted using a crane, making operation difficult. It was very troublesome. In addition, since both plugs are removed and transported, radioactivity leaks from the openings, and to prevent this, a transportable shutter must be used and the shutter must be transported together with the cask. This required an extremely troublesome operation.
