Claims
- 1. A scintillator comprising:a first neutron-sensitive phosphor constituent and a second thermophosphor constituent, the first and second constituents being homogeneously distributed in an optically transparent binder, the first phosphor converting neutron particles to charged alpha particles by neutron absorption when exposed to radiation interaction, and the second thermophosphor converting the charged alpha particles to scintillations which vary in accordance with variations in ambient temperature surrounding the scintillator, wherein the first constituent is Li6F and the second constituent is rare-earth activated Y2O3.
- 2. The scintillator according to claim 1, wherein the Li6F is 95% Li6F.
- 3. A scintillator comprising:a first neutron-sensitive phosphor constituent and a second thermophosphor constituent, the first and second constituents being homogeneously distributed in an optically transparent binder, the first phosphor converting neutron particles to charged alpha particles by neutron absorption when exposed to radiation interaction, and the second thermophosphor converting the charged alpha particles to scintillations which vary in accordance with variations in ambient temperature surrounding the scintillator, wherein the second constituent includes europium.
- 4. A scintillator comprising:a neutron-sensitive activated thermophosphor constituent homogeneously distributed in an optically transparent binder, and converting neutron particles to charged alpha particles by neutron absorption when exposed to radiation interaction, the thermophosphor constituent converting the charged alpha particles to scintillations which have a pulse decay time which varies in accordance with ambient temperature surrounding the scintillator, wherein the neutron-sensitive, activated thermophosphor constituent is neutron-sensitive, activated Y2O3.
- 5. A scintillator comprising:a neutron-sensitive activated thermophosphor constituent homogeneously distributed in an optically transparent binder, and converting neutron particles to charged alpha particles by neutron absorption when exposed to radiation interaction, the thermophosphor constituent converting the charged alpha particles to scintillations which have a pulse decay time which varies in accordance with ambient temperature surrounding the scintillator, wherein the neutron-sensitive activated thermophosphor is activated by gadolinium.
