Abstract

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.

巴勒斯坦和约旦使用的本地和进口烟草中的 210Po 和 210Pb 放射性水平。

本研究旨在评估巴勒斯坦和约旦各种烟草样本中 210Po 和 210Pb 的浓度。吸烟被认为是造成个人所受辐射剂量的一个重要因素，这主要是由于烟草中的 210Pb 和 210Po 含量较高。分析显示，巴勒斯坦当地烟草和香烟样本中 210Po 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/支香烟）。同样，这些样本中 210Pb 的平均浓度分别为 18.5 ± 2.6 mBq/g 和 20.3 ± 2.2 mBq/g，总平均浓度为 19.6 ± 8.1 mBq/g（17.0 mBq/支）。在约旦，香烟样本和狭叶烟草中 210Po 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 ± 9.1 mBq/g（18.0 mBq/支香烟）。9 mBq/g（18.0 mBq/支），而 210Pb 的平均浓度分别为 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）。计算了这些样本的吸烟者每年因吸入而产生的有效剂量。研究结果表明，某些调查样本中的 210Po 和 210Pb 放射性水平超过了世界上许多国家的研究结果。在巴勒斯坦，所有品牌产品的吸烟者每年的相关有效剂量从 34.7 μSv/y 到 186.5 μSv/y 不等，平均为 109.5 μSv/y；而在约旦，从 54.5 μSv/y 到 289.1 μSv/y 不等，平均为 130.9 μSv/y。

期刊介绍： This journal is devoted to fundamental and applied issues in radiation research and biophysics. The topics may include: Biophysics of ionizing radiation: radiation physics and chemistry, radiation dosimetry, radiobiology, radioecology, biophysical foundations of medical applications of radiation, and radiation protection. Biological effects of radiation: experimental or theoretical work on molecular or cellular effects; relevance of biological effects for risk assessment; biological effects of medical applications of radiation; relevance of radiation for biosphere and in space; modelling of ecosystems; modelling of transport processes of substances in biotic systems. Risk assessment: epidemiological studies of cancer and non-cancer effects; quantification of risk including exposures to radiation and confounding factors Contributions to these topics may include theoretical-mathematical and experimental material, as well as description of new techniques relevant for the study of these issues. They can range from complex radiobiological phenomena to issues in health physics and environmental protection.
