Alpha radiation from Polonium-210 (210Po) is considered to be an important agent of bronchial cancer in smokers. Besides reexamination of the radionuclide in domestic and imported cigarette brands separately, the radioactive contamination was also followed during the cigarette-producing procedure in Gilan as one of the major regions of tobacco cultivation in Iran. The activity level of 210Po in Iranian domestic and imported cigarettes averaged 38.4 ± 6% and 20.0 ± 7% mBq g-1, respectively. Drying in direct contact with fumes of fossil fuel seems like one of the main excessive sources of 210Po in Persian cigarettes.
钋-210（210Po）的α辐射被认为是吸烟者患支气管癌的一个重要因素。除了分别重新检测国产和进口香烟品牌中的放射性核素外，伊朗烟草种植的主要地区之一吉兰省在香烟生产过程中也对放射性污染进行了跟踪监测。国产和进口香烟中 210Po 的活度水平分别为 38.4 ± 6%和 20.0 ± 7% mBq g-1。直接与化石燃料烟雾接触干燥似乎是波斯香烟中 210Po 的主要过度来源之一。
