本題為「找錯題型」——詢問哪一項行為是不恰當的。內放射治療（密封源）的輻射防護三原則為時間（D）、距離與屏蔽（C 鉛衣、B 警示標誌）。B「保持病房門開啟」違反輻射屏蔽原則，會讓走廊人員暴露於不必要的輻射，故為不恰當行為。
This is an 'identify the incorrect action' question type. For internal (sealed-source) radiation therapy, the three principles of radiation protection are time (D), distance and shielding (C lead apron, B warning sign). Option C 'keeping the door open' violates the shielding principle, exposing hallway personnel to unnecessary radiation, and is therefore the inappropriate action.
