To provide a detection system having superior detection sensitivity.SOLUTION: A detection system comprises a formation member 26 forming a flow channel of detection-object liquid 25; and a detection device 1 detecting radiation in the detection-object liquid 25 flowing in the formation member 26. The detection device 1 comprises: a generation portion 2 which includes an aggregate 31 of phosphor particles 3 generating photons in response to incidence of radiation in the detection-object liquid 25, and a holding portion 4 which houses the aggregate 31 and through which the detection-object liquid 25 can flow; and a detection portion 5 detecting photons generated from the particles 3. The holding portion 4 comprises liquid passage portions 41 with openings 42 smaller than a particle diameter of the particles 3. The detection-object liquid 25 passes through the openings 42, thereby coming in contact with the particles 3.SELECTED DRAWING: Figure 1 【課題】優れた検出感度を有する検出システムを提供する。【解決手段】被検出液２５の流路を形成する形成部材２６と、形成部材２６を流れる前記被検出液２５中の放射線を検出する検出装置１と、を備え、検出装置１は、被検出液２５中の放射線の入射により光子を生成する蛍光体の粒子３の集合体３１と、集合体３１を収容するとともに被検出液２５を通液可能な保持部４と、を備える生成部２と、粒子３から生成された光子を検出する検出部５と、を備える。保持部４は、粒子３の粒径よりも小さな開口４２を有する通液部４１を備え、被検出液２５は、開口４２を通ることで粒子３と接触する。【選択図】図１
