The activity concentrations of ²¹⁰Pb and ²¹⁰Po in the most popular cigarettes and moassel tobacco brands consumed in Egypt were determined by the spontaneous deposition method using alpha spectrometry. It turned out that the activity concentration of ²¹⁰Po was higher than that of ²¹⁰Pb in all tobacco brands. Higher activity concentrations for both ²¹⁰Pb and ²¹⁰Po were found in cigarette than in moassel tobacco. The average activity concentrations of ²¹⁰Pb and ²¹⁰Po in cigarette tobacco were 11.79 ± 1.67 and 15.00 ± 1.83 mBq cig⁻¹, respectively, whereas in moassel tobacco the values were 7.08 ± 1.91 and 9.12 ± 1.12 mBq g⁻¹, respectively. The daily activities inhaled in the lung of a smoker and the inhalation effective doses due to cigarette and shisha smoking were calculated. The results revealed that the total ²¹⁰Pb and ²¹⁰Po daily activities inhaled and the total annual inhalation effective doses due to shisha smoking were two times greater than the corresponding values due to cigarette smoking. Also, the results indicated that the annual effective doses from inhalation of ²¹⁰Pb and ²¹⁰Po due to smoking 20 cigarettes per day are 14 and 16 times greater than the annual ingestion doses from the diet, respectively. In contrast, the annual effective doses from inhalation of ²¹⁰Pb and ²¹⁰Po due to shisha smoking (27 g moassel tobacco per day) are 26 and 33 times greater than the annual ingestion doses from the diet, respectively.

在埃及消费的最流行的卷烟和 moassel 烟草品牌中²¹⁰ Pb 和²¹⁰ Po的活性浓度是通过使用 α 光谱法的自发沉积方法确定的。结果表明，所有烟草品牌中²¹⁰ Po的活性浓度均高于²¹⁰ Pb。在卷烟中发现²¹⁰ Pb 和²¹⁰ Po 的活性浓度高于在 moassel 烟草中的活性浓度。卷烟烟草中²¹⁰ Pb 和²¹⁰ Po的平均活性浓度分别为 11.79 ± 1.67 和 15.00 ± 1.83 mBq cig ^-1，而在 moassel 烟草中，该值分别为 7.08 ± 1.91 和 9.12 ± 1.12 mBq g ^-1。计算吸烟者每日吸入肺内活动量和因吸烟和吸食水烟引起的吸入有效剂量。结果显示，吸水烟导致的每日活动吸入的总²¹⁰ Pb和²¹⁰ Po和总年吸入有效剂量是吸烟导致的相应值的两倍。此外，结果表明，吸入²¹⁰ Pb 和²¹⁰ Pb的年有效剂量由于每天吸 20 支烟而导致的 Po 分别是饮食中年摄入剂量的 14 倍和 16 倍。相比之下，由于吸食水烟（每天 27 克 moassel 烟草）而吸入²¹⁰ Pb 和²¹⁰ Po的年有效剂量分别是饮食中年摄入剂量的 26 倍和 33 倍。
