Sažetak
Common use of ionizing radiation in industry as well as health service stimulates the need for searching of the suitable radiation-sensitive materials, which can be used during unexpected exposition to radiation. A fast and reliable retrospective dosimetry method is very important for the prediction of health effects following an exposure. Electron paramagnetic resonance (EPR) glass dosimetry is a promising way to estimate radiation dose. However, the available studies give rather different results, especially in low dose range. Therefore, soda lime glass samples have been tested as potential dosimeters for low gamma doses using electron paramagnetic resonance (EPR). Radiation-induced EPR signals detected in powder samples and plates were compared. Basic dosimetric properties of the radiation-sensitive substances were studied, namely dose response, fading of the EPR signals and values of minimum detectable doses (MDDs). The variability of background signal (BKG) intensity was found as main factor causing the inaccuracy of radiation dose reconstruction in low dose range.
