Radiation detector, method of manufacturing radiation detector, and radiographic image capturing apparatus incorporating radiation detector

摘要

A radiographic image capturing apparatus includes a housing and a radiation detector accommodated in the housing. The radiation detector includes a scintillator for converting radiation into visible light and photodiodes for converting the visible light into electric charges. If it is assumed that a temperature-dependent rate of change in sensitivity of the scintillator with respect to the radiation is represented by A [%/K] and a temperature-dependent rate of change in sensitivity of the photodiodes with respect to visible light is represented by B [%/K], a scintillator and photodiodes are selected having temperature-dependent rates of change A and B that satisfy the following inequality (1):−0.35 [%/K]A+B0.35 [%/K]  (1).
