It can be freely configured, and all processes were performed on site to build the existing shielding facility, but the time required by the assembly method can be drastically reduced.

In addition, according to the block shield for building a radiation shielding facility according to an embodiment of the present invention, a shielding facility and a shielding facility construction method using the block shield, it is possible to maintain the best quality through mass production of the factory, simplifying the process and reducing the input manpower. It is possible to build a temporary shielding facility quickly and to dismantle it quickly after use, it is easy to repair damage and replace it with a new one, it is recyclable, and there is no longer a need for radiation shielding calculations suitable for the environment and conditions. As a result, it has the advantage of being able to construct a discontinued license without being constructed by an unprofessional general construction company.

In addition, the above-described apparatus and method are not limitedly applicable to the configuration and method of the above-described embodiments, but all or part of each of the embodiments may be selectively combined so that various modifications may be made to the above-described embodiments. It can also be configured.
