Abstract:
1. A method for manufacturing a radiation detector having, a radiation transmission substrate configured to transmit radiation there through; a scintillator layer formed on one principal surface of the radiation transmission substrate, the scintillator layer including an incident surface on which radiation is incident and an emission surface emitting light generated by the incident radiation and on a side opposite to the incident surface; and a light detection portion disposed on an emission surface side of the scintillator layer for detecting light emitted from the emission surface, wherein a side surface of the scintillator layer is inclined outwardly as the side surface advances from the incident surface to the emission surface, and the radiation transmission substrate has an outer edge portion that reaches the side surface of the scintillator layer, the method for manufacturing the radiation detector comprising: a scintillator layer forming step of forming the scintillator layer having a side surface inclining outwardly as the side surface advances from the emission surface to the incident surface by growing columnar crystals on the one principal surface of the radiation transmission substrate; a disposing step of disposing the one principal surface of the radiation transmission substrate on which the scintillator layer was formed in the scintillator layer forming step to face the light detection portion; and a deformation step of deforming the scintillator layer such that the side surface inclining outwardly as the side surface advances from the emission surface to the incident surface becomes a side surface inclining outwardly as the side surface advances from the incident surface to the emission surface, by pressing the radiation transmission substrate towards the opposing light detection portion.
