摘要

FIELD: physics.;SUBSTANCE: present invention relates to dosimetry of neutron radiation and can be used for stationary control of flux density and neutron fluence in the radiation zone of nuclear reactors, for periodic monitoring of the dosage of neutron radiation of reactor construction materials, for radiative study of materials, for use as detectors for tracking objects and medical purpose objects during sterilisation in a nuclear reactor, as well as for high-temperature measurement of neutron fluence in super-deep wells. To obtain the working substance for the thermoluminescent neutron detector based on sodium fluoride, activated by uranium, the initial reaction mixture is prepared in form of a mixture of ingredients, in which, besides sodium fluoride which is activated by uranium, also contains admixtures of scandium and copper in the following ratio of ingredients (mol.%): NaF 99.887-99.988, UO2(NO3)2 0.001-0.01, ScF3 0.01-0.1, CuF2 0.001-0.003. After that the mixture of initial ingredients is melted and from the melt, the working substance the thermoluminescent neutron detector is grown in form of crystals using Kyropoulos method on air.;EFFECT: obtaining working substance for thermoluminescent neutron detector, with the main operation "ТСЛ" peak in the high-temperature region at 520-525°C, resistant to neutron fluence of the nuclear reactor to 1016-1018 cm-2, stores light sum under the effect of neutrons and is capable of storing light sum for several years due to little fading.;2 dwg
