Samples of polymer composites based on polyprohylene (PP) with different volume content of binary compounds based on cadmium sulfide and zinc sulfide (CdS/ZnS) were formed and their thermo-luminescence photo-stimulated by ultraviolet (UV) irradiation before and after gamma radiation. The films from PP-(CdS/ZnS) composites with a thickness of 120± µm were obtained by hot pressing of pre-mixed powders of polymer and filler at the melting temperature of the polymer matrix and further cooling of the mixture in ice water. A comparative analysis of the spectra of thermoluminescence and photostimulated PP-(CdS/ZnS) composites by UV-irradiation was carried out. The thermoluminescence excited by the UV-irradiation and the modified original γ-irradiation of the composites based on PP filled with binary compound CdS/ZnS was in thesfocul of attention.
