AbstractAbstract
[en] The literature has shown that tobacco use causes damage to the health of cigarette users, manifesting itself in diseases with high mortality. Among these diseases include respiratory failure, pulmonary emphysema and lung cancer, among others. On the other hand, smoking contributes significantly to increasing the dose of natural radiation received by man, due to the presence of uranium series radionuclides, such as 226Ra, 210Pb and 210Po, in relatively high concentrations in fresh tobacco leaves. The determination of these radionuclides in this matrix is of great interest, once they can be incorporated not only by the active smoker, but also by the passive smoker. The results of this study confirmed the significant presence of 226Ra and 210Pb in tobacco samples collected and analyzed. The average values of activity concentration found in samples from the State of Alagoas were of Bq.kg-1 0.8 to 210Pb and 183.5 Bq.kg-1 to 226Ra. For samples coming from the State of Rio Grande do Sul, these values were 4,0 Bq.kg-1 to 210Pb and 161.3 Bq.kg-1 to 226Ra
