FIELD: physics.
SUBSTANCE: invention can be used for recording high-dose ionizing radiations. Essence of invention consists in the fact that in ceramics for recording of high-dose ionizing radiations, consisting of nano-sized aluminium oxide in α-phase, additionally in structure of initial matrix Ba2+ cation is introduced, at following ratio of components, wt. %: aluminium oxide 97.25…97.41, Ba2+ cation 0.54…0.64, other impurities 1.95…2.21.
EFFECT: technical result is enabling increase in range and sensitivity of detectors when detecting high-dose ionizing radiations.
