Provided is a scintillation neutron detector capable of measuring neutrons with precision even under a high amount of &#x3b3; rays as background noise and excellent in neutron counting precision, the scintillation neutron detector comprising a neutron scintillator crystal containingLi, and the crystal having a specific surface area of no less than 60 cm/cm.

Neutron detector

Provided is a radiation detector with improved n/&#x3b3; 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.
