Scintillator array, and radiation detector and radiation inspection apparatus using the same

Abstract

To provide an X-ray ceramic scintillator array as well as a radiation detector and a radiation inspection apparatus using the same, which prevents a resin used for a reflective layer of the scintillator array from being colored due to X-ray irradiation so as to realize a significant improvement against the output drop of the scintillator array. The resin used for the reflective layer of the X-ray ceramic scintillator array has a feature wherein a ratio of absorption intensity in a wavenumber range of 1490 cm−1 to 1750 cm−1 to absorption intensity in a wavenumber range of 2500 cm−1 to 2990 cm−1 has a value that falls within a specific range in an absorption spectrum based on Fourier transform infrared spectrometry (FT-IR).
