さらに、鋼板で仕切られた部屋を２階以上の階層に構築する場合、鋼板で仕切られた部屋は重量増となることから、鋼板で仕切られた部屋を支える柱や梁を強固なものにする必要があり、さらにコストが掛かるという不具合がある。
また、同じ建物内で原子力に関する研究、試験などを別の場所で行なう必要が生じた場合、コンクリートや鋼板などで仕切られた部屋を最初から構築し直さなければならず、多くの手間と時間を要し、コストが掛かるという不具合がある。
本発明は前記事情に鑑み案出されたものであって、本発明の目的は、放射線漏れを防止できる建物や部屋を軽量化、コストダウンを図りつつ構築する上で有利で、また、放射線漏れを防止できる部屋を同じ建物内で別の場所にコストダウンを図りつつ移す上で有利な放射線遮蔽パネルを提供することにある。 However, when constructing a building made of concrete or a room partitioned by concrete, it takes a lot of time and effort such as assembling the concrete formwork, curing the concrete for placement, and removing the formwork, which is costly. There is a problem.
Also, when constructing a room partitioned by steel plates, the heavy weight of the steel plates makes it difficult to transport and bring them in efficiently. However, there is a problem that the cost is high.
In addition, when building steel plate-partitioned rooms on the second floor or higher, the weight of the steel plate-partitioned rooms increases. There is a problem that it is necessary and costs more.
Also, if it becomes necessary to conduct research or testing related to nuclear power in a different location within the same building, a room partitioned by concrete or steel plates must be rebuilt from scratch, requiring a great deal of time and effort. However, there is a problem that the cost is high.
The present invention has been devised in view of the above circumstances, and an object of the present invention is to be advantageous in constructing buildings and rooms capable of preventing radiation leakage while reducing the weight and cost, and to prevent radiation leakage.
