Abstract
Provided is a radiation detector with improved n/γ discrimination and usable even under high counting rate conditions with a reduced load on a signal-processing system. The detector capable of distinguishing neutron and gamma-ray events includes: a scintillator; an optical filter; a first photodetector to which a first part of light emitted from the scintillator is introduced via the optical filter; and a second photodetector to which a second part of light emitted from the scintillator is introduced not via the optical filter, wherein, for a set of two wavelengths A and (A+B) nm, the scintillator emits at least a light of A nm and a light of (A+B) nm when irradiated by gamma-ray, and emits a light of A nm and does not emit a light of (A+B) nm when irradiated by neutrons; and the optical filter blocks the light of A nm and transmits the light of (A+B) nm.
