PROBLEM TO BE SOLVED: To provide a radiographing apparatus and radiographing system in which radiation can be stably detected even in the case where a change in exposure dose per unit time of radiation to be radiated during radiography is great.SOLUTION: A plurality of sensors 146 for detecting radiated radiation with different sensitivities with respect to radiation are disposed so as to be overlapped with a radiation detector 60, and the plurality of sensors 146 are comprised of a plurality of unit elements with different light receiving areas. Therefore, even in the case where a change in exposure dose is great, radiation can be stably detected and further, the plurality of sensors 146 are used in accordance with purposes, thereby detecting the exposure start, exposure end and exposure dose of radiation.COPYRIGHT: (C)2012,JPO&INPIT【課題】撮影時に照射される放射線の単位時間当たりの照射量の変化が大きい場合でも、放射線の検出を安定して行える放射線撮影装置及び放射線撮影システムを提供する。【解決手段】放射線に対する感度が異なり、各々照射された放射線を検出する複数のセンサ部146を放射線検出器60と重なるように配置し、複数のセンサ部146を受光面積が異なる複数の単位素子で構成することで、照射量の変化が大きい場合でも安定して放射線を検出でき、また、複数のセンサ部146を目的に応じて使用することで、放射線の照射開始、照射終了、照射量を検出することが可能となる。【選択図】図4
