Abstract
Abstract An assessment of 210Po and 210Pb concentrations in tobacco samples from Turkey was conducted for this study. Although tobacco contains elevated levels of 210Pb and 210Po, smoking is recognized to be a significant contributor to radiation doses received by individuals. The chemical separation process and Alpha spectroscopy were applied to determine 210Pb and 210Po. According to this analysis, the activity concentrations 210Po in cigarette samples ranged between 5.28 ± 0.15 mBq/g to 27.15 ± 2.10 mBq/g, with an average of 14.69 ± 0.68 mBq/g. Similarly, the activity concentration 210Pb in cigarette samples was obtained from 5.11 ± 0.14 mBq/g to 22.08 ± 1.36 mBq/g, with an average of 12.36 ± 0.37 mBq/g. Inhalation of 210Po and 210Pb with cigarette smoke was used to calculate the annual effective doses. The mean values of the annual effective dose from 210Po and 210Pb for smokers were estimated to be 117.77 μSv/y and 98.97 μSv/y respectively. It can be concluded from the above that smoking cigarettes and absorbing 210Po and 210Pb through the respiratory system are the main sources and the principal pathways through which smokers can receive doses.
