Inter-comparison of OSL response of irradiated salted crackers between Croatian and Italian laboratories for retrospective dosimetry purposes
Introduction: In retrospective dosimetry, for the radiation and nuclear (R/N) emergency if uncontrolled radiation affected many people or the environment, the information about radiation doses allows for the prediction of the biomedical consequences. Therefore, when professional dosimeters are not available, objects of everyday use can be applied as dosimeters. In such cases, the method of optically stimulated luminescence (OSL) has proved very promising. Methods: The salt, following the exposure to ionizing radiation, exhibits a particularly high OSL response compared with many other materials. In this study, radiation sensitivity of salty crackers available on the market was monitored with two PSL systems in two physical dosimetry laboratories (ISS, Italy and RBI, Croatia) using the validated PSL methods. The response at two stimulation 890 nm and 470 nm have been compared. Results: The results indicate that salty snacks can be used in accident dosimetry. The stimulation by 470 nm has better response, but for both stimulations detect absorbed doses are below 100 mGy. Conclusion: The obtained data, showed good agreement between both laboratory OSL readout suggesting additional benefit to the use of salty crackers in the retrospective dosimetry. The study was supported by NATO Science for Peace and Security Programme, grant No. G5684.
