Abstract
210Po and 210Pb concentrations have been determined in 58 cigar brands manufactured in 11 countries. Cuban and American cigars showed the lowest 210Po content. The mean levels of 210Po in Brazilian, European and Dominican cigars were almost identical and somewhat lower than the levels observed for cigars from other Latin American countries. Cuban, American and European cigars contained low levels of 210Pb. Cigars from the remaining countries contained twice as much 210Pb. The mean 210Po/210Pb ratio showed an excess of polonium. In the case of a one cigar-a-day smoker, the calculated annual absorbed dose due to 210Po is -16 mGy.
