Po and Pb occur naturally and are the most radiotoxic isotopes of the uranium (U) decay chain. Samples of and related mushroom species, including , , and , collected from Poland and Belarus were investigated for the activity concentrations of these isotopes and also for their potential health risk through adult human consumption. The results showed that spatially, the occurrence of Po and Po was heterogeneous, with activities varying from 0.91 to 4.47 Bq∙kg dry biomass and from 0.82 to 5.82 Bq∙kg db, respectively. Caps and stipes of the fruiting bodies showed similar levels of contamination. Consumption of boletes foraged in Poland could result in exposure to a combined radiation dose of 10 µSv∙kg db from both isotopes. This dose is not significant compared to the total annual effective radiation dose of Po and Pb (54-471 µSv∙kg) from all sources, suggesting that these mushrooms are comparatively safe for human consumption.
钋和铅是铀（U）衰变链中最具放射性毒性的同位素，它们天然存在。本研究调查了来自波兰和白俄罗斯的 和相关蘑菇物种（包括 、 、 和 ）样本中这些同位素的活度浓度，以及通过成人食用这些蘑菇可能带来的潜在健康风险。结果表明，在空间上，Po 和 Po 的存在具有异质性，其活度分别为 0.91 至 4.47 Bq·kg 干生物量和 0.82 至 5.82 Bq·kg 干重。菌盖和菌柄的污染水平相似。在波兰采集的牛肝菌食用后，可能会使两种同位素共同导致 10 μSv·kg 干重的辐射暴露。与来自所有来源的 Po 和 Pb（54-471 μSv·kg）的总年有效辐射剂量相比，这个剂量并不显著，这表明这些蘑菇对人类食用相对安全。
