Taking into consideration the data of Table 1 for the radionuclide concentrations (Bq kg 1 ) in tobacco dry leaves, the fraction of the radionuclide activity concentration that is recovered from cigarette tobacco to cigarette smoke is 0.75 (75 %), as on the average, about 75 % of the radioisotope in the cigarette tobacco was contained in the cigarette smoke, which is partially inhaled and deposited in the lung tissues and about 25 % was retained in the cigarette filter and ash [18] and the most recent dose conversion coefficients of the radionuclides (Sb Bq 1) for the case of inhalation for adults (smokers) as presented in Table 2, then the data of Table 3 are derived for the annual effective dose, H E (Sv y 1 ), due to inhalation for adults (smokers), according to the equation: where M T (kg y 1 ) refers to the annual amount (in mass) of tobacco consumed, Ci (Bq kg 1 ) refers to the concentration of the ith radionuclide, and F (Sv Bq 1 ) refers to the dose conversion factor [2528]
