FIELD: physics.
SUBSTANCE: invention relates to scintillation radiation detectors. Essence of the invention consists in the fact that the ionizing radiation detector comprises a scintillation radiation detector and a photodetector, between which, directly on the surface of the scintillation detector, there is a transparent for optical radiation monolayer meso-sized particles (microfocusers) and with a characteristic size of not less than λ/2, where λ is the wavelength of the used radiation with a relative refraction index of the material lying in range of 1.2 to 1.7, forming on their outer boundary on the opposite side from the incident radiation regions with high radiation intensity with transverse dimensions of the order λ/3-λ/4.
EFFECT: high sensitivity of the detector of ionizing radiations.
