SCINTILLATION COMPOSITION FOR NEUTRON DETECTION Russian patent published in 2022 - IPC G01T1/202 

FIELD: ionizing radiation registration.

SUBSTANCE: invention relates to the field of registration of ionizing radiation. The scintillation composition for detecting neutrons contains a scintillator, a neutron absorber and a binder. The addition of ⁶Li atoms to the composition of the binder makes it possible to increase the efficiency of neutron absorption, reduce energy losses, and reduce the mean free path of helium and tritium nuclei between ⁶Li nuclei and scintillator grains in the composition. In this case, the ratio of the number of gadolinium atoms Gd and ⁶Li can vary widely, allowing neutrons to be detected mainly by the reaction of radiative capture (n, γ), or by the reaction of absorption of neutrons by ⁶Li nuclei, accompanied by the emission of helium and tritium nuclei.

EFFECT: improvement of spatial resolution and productivity of measurements during neutron registration.
