The re-search objects are barium ditionate (BaS2O6), magnesium sulfate (MgSO4), in which radiation paramagnetic centers are formed under the influence of ionizing radiation. The research was carried out by the method of electron paramagnetic resonance using the EPR spectrometer of the Varyan type E-12; measurements are made in the X-band. In the course of the project, the technological process of manufacturing dosimetric sensors in the form of tablets and plates, the active substance of which is powder di-thionate barium or magnesium sulfate, is developed. The main dosimetric parameters of the manufactured dosimeters are obtained. The main dosimetric parameters of bar-ium and magnesium sulfate dithionate: the spectrum has one narrow line of width Hpp = 0.55mT, the dependence on the radiation dose is linear to 5 ? 104 Gr. A patent for a high-temperature detector of ?-radiation for EPR dosimetry has been obtained. Developed powdered plates of magnesium sulfate can be used to create sensory ele-ments of EPR dosimetry of small, medium and large doses of gamma radiation. De-veloped dosimeters also detecte X-ray and beta-radiation, protons and neutrons. The practical significance of the project is that sensors made of ditionate barium and magnesium sulfate can be used for dosimetry of irradiation in medicine, in monitor-ing the radiation environment, the staff of nuclear reactors, particle accelerators in emergencies.
