Measurement of natural radionuclides in drinking water and risk assessment in a volcanic region of italy, campania
No full textThe physical–chemical properties of water are closely linked to the geological nature of the site where they are located. This aspect becomes even more interesting when analyzing the natural radionuclides in the drinking water of a volcanic territory such as Campania in southern Italy. This study concerned the measurement of activity concentration of gross alpha and beta, radon, and tritium to evaluate their biological impact. The measurements were carried out using alpha spectrometry for alpha emitters, proportional counter for beta emitters, the electret system for radon in water, and finally liquid scintillation for the measurement of tritium concentration. The biological impact was assessed considering the indicative dose, if applicable, and the effective annual dose of radon. Although the results show that the values are below international and national references, the radiological characterization of drinking water is of fundamental importance to optimize the radiation protection of the population
Environmental radiation and risk perception: A survey in the Campania region (Southern Italy)
No full textA study about the risk perception from exposure to environmental radiation, in particular to radon gas, through an online survey has been carried out. The rationale has been the definition of the concepts of risk and danger and the analysis of the European and Italian legislative context regarding information on exposure to ionizing radiation. Two test populations were involved: general and student population. The results showed that the perceived risk is different from the real risk and that the knowledge of the issue is related to the level of education and the cultural background. Furthermore, the influence of dissemination activities and educational projects with high schools on the level of knowledge of gas radon is evident

No full textA study to evaluate the feasibility of using a system routinely used for measurements of radon gas concentration for measuring the background of gamma radiation was carried out. This approach would reduce the employment of different detectors to a single type, standardizing the methodology adopted and reducing the costs affecting other types of detectors. A 1440 hours long measurement was performed, using an experimental EIC system. The results were compared with measurements provided by a proportional counter and thermoluminescence dosimeters used as a reference. The results suggest the potential of the EIC system for unconventional use for gamma radiation background measurements
