摘要:
A neutron measurement apparatus 1A includes a neutron detection unit 10, a photodetection unit 20 that detects scintillation light emitted from the neutron detection unit 10, a light guide optical system 15 that guides the scintillation light from the neutron detection unit 10 to the photodetection unit 20, and a shielding member 30 which is located between the neutron detection unit 10 and the photodetection unit 20 for shielding radiation passing in a direction toward the photodetection unit 20. Further, a scintillator formed of a lithium glass material in which PrF3 is doped to a glass material 20Al(PO3)3-80LiF is used as a neutron detection scintillator composing the neutron detection unit 10. Thereby, the neutron detection scintillator and the neutron measurement apparatus which are capable of suitably performing neutron measurement such as measurement of scattered neutrons from an implosion plasma can be realized.
