SCINTILLATION MATERIAL ON BASIS OF A MONOCRYSTAL OF POTASSIUM DIHYDROPHOSPHATE AND A DETECTOR ON ITS BASIS

摘要

The invention relates to means of scintillation engineering, in particular to crystalline scintillators for production of detectors for registration of ionizing radiation in dosimetry of which neutrons under conditions of mixed neutron and gamma-fluxes of radiation. Scintillation material on basis of a monocrystal of potassium dihydrophosphate is additionally activated with cerium-organic complex with coefficient of coherent conjugation fromto, at that concentration of cerium (Ce) in the monocrystal is from 0.01 to 0.001 mass. %. Scintillation detector includes a scintillation element that is optically connected to the photo-receiver. The scintillation element is made of a monocrystal of potassium dihydrophosphate activated with cerium-organic complex with coefficient of coherent conjugation fromto, at concentration of Ce in the monocrystal from 0.01to 0.001 mass. %. The invention provides selective registration of quick neutrons in mixed fluxes of neutron and gamma-radiation.
