Zusammenfassung:	To measure, inside a controlled area, the radiation dose equivalent to the radiation dose leaked outside of a controlled area.SOLUTION: A first radiometer unit 10 includes a first radiometer 12, and a first radiometer container 14. The first radiometer container 14 contains the first radiometer 12 used inside a radiation controlled area 30 in which an X-ray device 50 is installed. The first radiometer container 14 includes a first part 14a positioned between the X-ray device 50 and the first radiometer 12. A material and thickness of the first part 14a is selected so as to have an X-ray shielding property equivalent to an upper boundary wall 34 of the radiation controlled area 30.SELECTED DRAWING: Figure 1 【課題】管理区域外に漏洩する線量と同等の線量を管理区域内で計測する。【解決手段】第１線量計ユニット１０は、第１線量計１２と、第１線量計容器１４とを備える。第１線量計容器１４は、Ｘ線装置５０が設置される放射線管理区域３０内で使用する第１線量計１２を収容する。第１線量計容器１４は、Ｘ線装置５０と第１線量計１２の間に位置する第１部分１４ａを有する。第１部分１４ａは、放射線管理区域３０の上部境界壁３４と同等のＸ線遮蔽能力を有するように材料および厚さが選択される。【選択図】図１
