Dosimetry of high doses of ionizing radiation is a method widely used not only in the field of basic and applied research but also in various industries. High-dose irradiation is used in the sterilization of foodstuffs and prolongation of their shelf life, sterilization of tools, materials and wastewater, treatment of antiquities attacked by woodworm organisms, biological and genetic research, inhibition of seed germination and retardation of fruit ripening. Furthermore, it has been applied in radiation resistance testing of materials, defectoscopy, industrial irradiation of materials (e.g. crosslinking and grafting of polymers or gemstone coloring by ionizing radiation), and last but not least, of course, nuclear energetics. In this work the dosimetric properties of polycarbonate are studied. They are compared with a standardized and certified method using alanine dosimeters. In the case of gammas the testing was realized for 60Co and neutron radiation was studied in the research nuclear reactor LVR-15.

Development of a standard dosimetric facility with protection against external radiation background for the metrological support of highly sensitive radiation monitoring devices in accordance with the requirements of international standards .

The aim of this research is to study the use of polycarbonate as a reusable radiochromic integrating dosimeter for the determination of high doses of ionizing radiation in the (range of 0.1 to 10 kGy). The region of the linear dependence of the optical density of polycarbonate samples on gamma radiation dose, as well as the fading of the radiation effect and the possibility of accelerating this fading by annealing have been explored. To determine the effect of oxygen concentration on changes in optical density and the rate of oxygen diffusion into the polycarbonate, some samples were stored in a pure oxygen atmosphere, produced by electrolytic dissociation of distilled water using a fuel cell.
