PROBLEM TO BE SOLVED: To provide a storage device enabling a radiation detector stored therein with a detection face facing a side to be used while performing charging.SOLUTION: A storage device can store a radiation detector including: a radiation detection panel detecting a radiation incident on an incident plane an electric circuit board controlling driving of the radiation detection panel a secondary battery supplying electrical power to the electric circuit board and an electric power reception part for charging the secondary battery. The storage device includes: a storage part capable of storing the radiation detection device with the incident plane facing a side and an electric power supply part supplying electric power to the electric power reception part of the radiation detection device. The storage part has a higher radiation transmission rate with the radiation detection device stored therein in an orthographic projection area where at least an effective detection area of the radiation detection panel is orthographically projected than a radiation transmission rate in other areas than the orthographic projection area in a front face wall facing the incident plane.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】検出面を側方に向けた状態で収納された放射線検出装置を、充電しながら使用することができる収納装置を提供する。【解決手段】入射面に入射した放射線を検出する放射線検出パネルと、該放射線検出パネルの駆動を制御する電気回路基板と、該電気回路基板に電力を供給する二次電池と、該二次電池を充電するための電力受電部とを有する放射線検出装置を収納可能な収納装置は、該入射面を側方に向けた状態で該放射線検出装置を収納可能な収納部と、該放射線検出装置の該電力受電部に電力を供給する電力供給部と、を有し、該収納部は、該放射線検出装置が収納された状態において、該入射面と対向する前面壁のうち、少なくとも前記放射線検出パネルの有効検出領域が正投影された正投影領域の放射線透過率が、該正投影領域とは異なる領域の放射線透過率よりも高い。【選択図】 図1
