Natural radioactivity in cigarette tobacco and radiation dose induced from smoking (original) (raw)

10th Jubilee International Conference of the Balkan Physical Union, 2019

Abstract

This study aims to assess for the first time the natural radioactivity and radiation dose induced from smoking. Different brands of tobacco cigarettes, commonly marketed in Albania, were collected in 10 packs of 20 cigarettes each. A broad energy High-Purity Germanium (HPGe) system, with relative efficiency 40%,has been used in order to determine the radionuclides present in cigarette tobacco. The LabSOCS (Laboratory SOurceless Object Calibration Software) was used to simulate the absolute efficiency curve for organic matrix in the energy range from 20 keV to 2000 keV. The average values of the activity concentrations were 13.4 ± 3.7, 5.3 ± 2.3, 839.1 ± 29 Bq/kg for 226Ra (214Bi, 214Pb), 232Th (228Ra, 228Th) and 40K, respectively. The artificial radionuclide of 137Cs was found to be under the detection limit for the measured cigarette tobaccos. These results were compared with available data in the literature. The annual effective dose, the annual gonadal dose equivalent and the excess life cancer risk was calculated to evaluate the radiological hazard for smokers in Albania.This study aims to assess for the first time the natural radioactivity and radiation dose induced from smoking.
