Sažetak
In the case of a mass-casualty radiological or nuclear (R/N) event, the grouping of individuals into those requiring medical care and those who were not affected during the accident is urgent. Often, the people involved do not own a professional dosimeter and therefore the dose assessment relies on fortuitous dosimeters. This study focuses on the possibility of using costal sand as a fortuitous dosimeter in a R/N emergency. A significant number of papers regarding the optically stimulated luminescence (OSL) response of dating of sediments has been published, but none on the application proposed in this work. Advantages of using a portable OSL reader are the rapidity of the measurement, the undemanding sample preparation and the user friendliness of the instrument. The signals obtained from irradiated (1 Gy) and unirradited sand were acquired right after irradiation and compared for three different light stimulations (infrared, blue light and both combined). Moreover, the signal of the irradiated sample was recorded 24 h after irradiation to study the signal stability. Results indicated that it is possible to differentiate between unirradiated sand and the one irradiated with 1 Gy. Moreover, the signal appears to be stable 24 h after the irradiation (changes withing 1SD). Therefore, the obtained results, along with the advantages of the instrument, suggest that this method could be convenient for a fast categorization of civilians in a R/N accident.
