An inorganic scintillator has been proposed for use as a selective detector for visualization and effective registration of high-density pulsed electron beams against the background of α-, β-, γ-nuclear radionuclide emissions, in particular, for visualization and registration of electron beams generated by high-current electron accelerators nano- and picosecond range. The essence of the invention: the use of known semiconductor crystals of mercury iodide HgI ₂ (red tetragonal modification) as an inorganic scintillator having high scintillation efficiency C _rel when registering high-density electron beams and practically not sensitive as a scintillator to nuclear α-, β-, γ-radiation radionucidides. Parameters like scintillator HgI _2: C _rel = 10.1 (compared with Csl - Te), τ = 2,1 ms, λ = 575-580 nm _rad, Z _ef = 67.3.
