INDOOR RADON CONCENTRATION MEASUREMENTS AT EDIRNE CITY CENTER

When radon gas and its decay products is inhaled in residential buildings, it can damage the lung tissue and cause lung cancer over time. At different parts of Edirne city, for 54 houses, radioactivity concentrations of radon gas have been measured at living room and bedroom. In this present work, indoor radon concentrations were measured by using passive nuclear track detectors (CR-39). According to the results of the study, it was concluded that the concentration of radon is 2-125 Bq/m3. It was understood that the concentration of average radon obtained was 27.58 Bq/m3. In this study, as a result of exposure to radon gas from the annual effective dose equivalent was obtained to be 0.728 mSv. Measuring radon levels and annual effective doses were determined to be within recommended limits. Corresponding annual effective doses and risk probability for lung cancer due to the indoor radon inhalation were calculated and the results were discussed
