Now, in a shelter in an urban area means you have to be either in a basement as deep as possible, or you have to be on a floor -- on a high floor -- if it's a ground burst explosion, which it would be, higher than the ninth floor. So you have to be tenth floor or higher, or in the basement.
躲在城市里的避难所指的是 要么躲在地下室，越深越好 要么躲在楼上，越高越好 如果是爆炸发生在地面上 辐射尘可能会到达9楼。所以 你需要跑到10楼或者更高的楼层 或者躲到地下室
