In this study, the activity concentration of polonium 210 in cigarette for Tunisian consumers was investigated by alpha spectrometry. After chemical digestion of tobacco, ²¹⁰Po was extracted, auto-deposited on disc and measured. The activity of ²¹⁰Pb was assessed after radioactive equilibrium was achieved. The activity levels of ²¹⁰Po ranged between 7.8 ± 0.3 and 17 ± 0.5 mBq per cigarette with an average of 12.9 ± 0.4 mBq per cigarette. Effective doses per year due to cigarette smoking were calculated assuming that 22% of the ²¹⁰Pb and ²¹⁰Po in tobacco were retained in the lungs of the smokers. It is concluded that for a smoker in Tunisia, the average effective dose is about 90.6 ± 3.3 μSv per year for a cigarette consumption of one pack of cigarettes per day. This value is somewhat lower than 106.4 ± 5.3 μSv per year estimated as the mean global effective dose from smoking.

在这项研究中，通过α光谱法研究了突尼斯消费者中香烟中po 210的活性浓度。对烟草进行化学消化后，提取²¹⁰ Po，自动沉积在圆盘上并进行测量。达到放射性平衡后评估²¹⁰ Pb的活性。每支香烟的²¹⁰ Po活性水平介于7.8±0.3和17±0.5 mBq之间，平均每支香烟为12.9±0.4 mBq。假定由于²¹⁰ Pb和²¹⁰中22％的吸烟量，每年计算出的有效吸烟量烟草中的宝保留在吸烟者的肺部。结论是，对于突尼斯的一名吸烟者来说，每天吸一包香烟的平均有效剂量约为90.6±3.3μSv。该值略低于每年106.4±5.3μSv（估计为吸烟的总体平均有效剂量）。
