SCINTILLATION DETECTOR OF NEUTRON AND GAMMA RADIATION Russian patent published in 2002 - IPC

FIELD: radiation monitoring. SUBSTANCE: scintillation detector can be used in custom houses, units of State Atomic Supervision, in systems of special radiation monitoring of nuclear submarines subject to stripping, in detection and identification of fissionable materials ( uranium, plutonium, californium ) and articles from them, and materials related to class of radioactive substances-gamma radiation sources. Scintillation detector of neutron and gamma radiation includes sensor coming in the form of two scintillators connected in parallel: external neutron scintillator based on plastic material (CH)_n or stilbene ( scintillator with well ) placed into jacket of boroncarrying (boron nitride or carbide ) material and internal scintillation crystal Nal-T1 located in well of external scintillator in standard container and sensitive to gamma radiation, photoelectron multiplier positioned in jacket of boron nitride or carbide ( natural mixture of isotopes of boron or isotope 105
