ABSTRACT Herbs are an important part of traditional medicine in Poland. Therefore, the aim of this study was the determination of polonium 210Po in 48 selected medicinal herb samples from the Polish market. The activity concentrations of 210Po were measured using alpha spectrometry. The activity concentration of 210Po was in the range from 0.3 ± 0.1 to 28.2 ± 0.4 Bq kg–1. The obtained results were compared with corresponding studies conducted worldwide. A higher 210Po activity concentration was observed in the above-ground part of plants. The obtained results show that the highest 210Po activity concentration was observed in evergreen plants and winter-hardy plants. Yet even infusions with 2 g of the most contaminated herbs examined were considered to be radiologically safe.

来自波兰的流行药材中的 210Po

摘要 草药是波兰传统医学的重要组成部分。因此，本研究的目的是测定来自波兰市场的 48 种精选药草样品中的钋 210Po。使用α光谱法测量210Po的活性浓度。210Po 的活性浓度范围为 0.3 ± 0.1 至 28.2 ± 0.4 Bq kg-1。获得的结果与世界范围内进行的相应研究进行了比较。在植物的地上部分观察到较高的 210Po 活性浓度。所得结果表明，在常绿植物和耐寒植物中观察到最高的 210Po 活性浓度。然而，即使输注 2 克受污染最严重的草药，也被认为在放射学上是安全的。
