Radiation detection apparatus, radiation detection system and method of manufacturing radiation detection apparatus

A method of manufacturing a radiation detection apparatus, the method comprising:

• a first step of manufacturing a scintillator panel by bonding a scintillator protective layer to a scintillator layer, which converts radiation into light, so as to protect the scintillator layer;
• and
• a second step of bonding the scintillator panel to a sensor panel including a sensor array in which a plurality of photoelectric converters which detect light from the scintillator layer are arranged and a sensor protective layer which protects the sensor array,
• wherein in the first step, the scintillator protective layer is bonded to the scintillator layer by decreasing viscosity of the scintillator protective layer by heating the scintillator protective layer, and then increasing the viscosity by cooling the scintillator protective layer, and
• in the second step, the scintillator panel is bonded to the sensor panel by decreasing the viscosity of the scintillator protective layer by heating the scintillator protective layer, and then increasing the viscosity by further heating the scintillator protective layer.
