    Abstract: A magnetically shielded room has four walls (22), a floor (24), and a ceiling (20). One of the walls has a doorway (26) therethrough, and a sliding door (32) is provided to close the doorway. Each of the four walls, the floor, the ceiling, and the door is formed of at least one layer of electrically conductive material (40) to exclude radio frequency energy from the interior of the room, and at least one layer of high magnetic permeability material (42) to exclude magnetic fields from the interior of the room. Preferably, at least the wall with the doorway therethrough and the door are formed of two electrically conductive plates (54) and a layer of high magnetic permeability material (58) on each of the plates, the electrically conductive plates of the wall being spaced sufficiently far apart that the sliding door slides into the space between the plates when the doorway is opened. In this preferred approach, the door is mechanically, electrically, and magnetically sealed to the doorway in the wall by inflating bladders (56) in the door that force the electrically conductive plates (54) of the door against the respective plates of the wall (70), and the high magnetic permeability layers (58) of the door against the respective layers of the wall.

    Abstract translation: 磁屏蔽室具有四个壁（22），一个地板（24）和一个天花板（20）。 其中一个墙壁具有穿过其中的门口（26），并且提供滑动门（32）以关闭门口。 四个墙壁，地板，天花板和门中的每一个由至少一层导电材料（40）形成，以排除房间内部的射频能量，以及至少一层高磁导率 材料（42），以从房间的内部排除磁场。 优选地，至少具有通孔门和门的壁由两个导电板（54）和每个板上的高磁导率材料层（58）形成，壁的导电板充分间隔开 远离门，当门口打开时，滑动门滑入板之间的空间。 在这种优选的方法中，通过使门中的气囊（56）膨胀来将门机械地，电气地和磁性地密封到壁上的门口，所述气囊迫使门的导电板（54）抵靠壁的各个板（54） 70）和门的高磁导率层（58）抵靠壁的各个层。
