Abstract

²¹⁰Po is the main radiotoxic chemical in tobacco smoke and one of the primary causes of lung cancer. Investigating ²¹⁰Po concentration in tobacco is important in estimating the annual effective dose (AED) due to smoking. In this study, the ²¹⁰Po concentrations in tobacco leaves and soil in Quang Xuong, Vietnam were measured using a high-resolution passivated and implanted planar silicon detector. Based on these data the AEDs to smokers were estimated. The ²¹⁰Po activity concentration in tobacco varied significantly from 28.7 to 254.0 mBq g⁻¹, whereas its variation in soil was insignificant. The AED due to smoking fresh tobacco leaves in Vietnam (average 565 μSv y⁻¹) was significantly higher than the values reported for other countries (36–361 μSv y⁻¹).

越南广雄市土壤和烟叶中的 210PO 以及吸烟者的年有效剂量估算

 抽象的

²¹⁰ Po是烟草烟雾中主要的放射性毒性化学物质，也是肺癌的主要原因之一。研究烟草中的²¹⁰ Po 浓度对于估计吸烟引起的年有效剂量 (AED) 非常重要。在这项研究中，使用高分辨率钝化植入式平面硅探测器测量了越南广雄市烟叶和土壤中²¹⁰ Po 的浓度。根据这些数据，对吸烟者的 AED 进行了估计。烟草中的²¹⁰ Po 活性浓度在 28.7 至 254.0 mBq g ^-1之间变化显着，而土壤中的变化不显着。越南因吸食新鲜烟叶而产生的 AED（平均 565 μSv y ^-1 ）明显高于其他国家报告的值（36–361 μSv y ^-1 ）。
