The thesis solves the problem of optimization of technological approach to obtain polycrystalline scintillation materials for short-range detection of ionizing radiation, which is one of most dangerous radiation to human health. We investigated the effect of preparation conditions of a source material (Van der Waals' single crystalline grains) and parameters of pressing on characteristics of polycrystalline scintillators. The possible ways of obtaining a source material for manufacturing polycrystalline scintillators stilbene, anthracene, undoped and doped by 1,4-diphenyl-1,3-butadiene, p- terphenyl was investigated.It is shown that the application of zone melting to prepare a raw material, without the stage of growing a single crystal, reduces the cost of the production of a polycrystalline scintillator, and allows making polycrystalline scintillators with higher values of light output.
