This study aimed to assess the concentrations of ²¹⁰Po and ²¹⁰Pb in various tobacco samples from Palestine and Jordan. Cigarette smoking is recognized as a significant contributor to the radiation dose received by individuals, primarily due to the elevated levels of ²¹⁰Pb and ²¹⁰Po found in tobacco. The analysis revealed that the average concentrations of ²¹⁰Po in locally sourced tobacco and cigarette samples in Palestine are 16.8 ± 2.3 mBq/g and 18.5 ± 2.0 mBq/g, with a total average of 17.8 ± 7.4 mBq/g (15.5 mBq/cigarette). Similarly, the average concentrations of ²¹⁰Pb in these samples are 18.5 ± 2.6 mBq/g and 20.3 ± 2.2 mBq/g, with a total average of 19.6 ± 8.1 mBq/g (17.0 mBq/cigarette). In Jordan, the average concentrations of ²¹⁰Po in cigarette samples and narghile tobacco are 20.1 ± 2.4 mBq/g and 18.3 ± 4.1 mBq/g, with a total average value of 19.6 ± 9.9 mBq/g (18.0 mBq/cigarette), while the average concentrations of ²¹⁰Pb are 22.2 ± 2.6 mBq/g and 20.2 ± 4.5 mBq/g, with a total average value of 21.6 ± 10.8 mBq/g (19.9 mBq/cigarette). The annual effective doses resulting from inhalation were calculated for smokers of these samples. The findings revealed that the levels of ²¹⁰Po and ²¹⁰Pb radioactivity in certain investigated samples exceeded the results of studies in many countries of the world. The associated effective doses per year from smoking for all brands products in Palestine range from 34.7 μSv/y to 186.5 μSv/y with an average of 109.5 μSv/y, while in Jordan 54.5 μSv/y to 289.1 μSv/y with an average of 130.9 μSv/y.

本研究旨在评估来自巴勒斯坦和约旦的各种烟草样品中²¹⁰ Po 和^{210 Pb 的浓度。}吸烟被认为是个人接受辐射剂量的一个重要因素，这主要是由于烟草中发现的²¹⁰ Pb 和²¹⁰ Po 水平升高。分析显示，巴勒斯坦当地采购的烟草和卷烟样品中²¹⁰ Po 的平均浓度分别为 16.8 ± 2.3 mBq/g 和 18.5 ± 2.0 mBq/g，总平均值为 17.8 ± 7.4 mBq/g（15.5 mBq/支烟） ）。^{同样，这些样品中210} Pb的平均浓度为 18.5 ± 2.6 mBq/g 和 20.3 ± 2.2 mBq/g，总平均值为 19.6 ± 8.1 mBq/g（17.0 mBq/支烟）。^{在约旦，卷烟样品和水烟烟草中210} Po的平均浓度分别为 20.1 ± 2.4 mBq/g 和 18.3 ± 4.1 mBq/g，总平均值为 19.6 ± 9.9 mBq/g（18.0 mBq/支烟），而²¹⁰ Pb的平均浓度为 22.2 ± 2.6 mBq/g 和 20.2 ± 4.5 mBq/g，总平均值为 21.6 ± 10.8 mBq/g（19.9 mBq/支烟）。计算了这些样本的吸烟者因吸入而产生的年有效剂量。^{调查结果显示，某些调查样品中的210} Po 和²¹⁰ Pb 放射性水平超出了世界许多国家的研究结果。在巴勒斯坦，所有品牌产品每年吸烟产生的相关有效剂量范围为 34.7 μSv/y 至 186.5 μSv/y，平均为 109.5 μSv/y，而在约旦则为 54.5 μSv/y 至 289.1 μSv/y，平均为 109.5 μSv/y。 130.9μSv/年。
