Presented are results of a study on accumulation and distribution of Po and Pb in the fruitbodies of parasol mushroom (Macrolepiota procera) and risk to human consumer due to exposure from highly radiotoxic decay particles emitted by both radionuclides. Mushrooms were collected from 16 forested places in central and northern regions of Poland. Activity concentrations of Po and Pb were determined after radiochemical separation of nuclides and subsequent measurement using validated method and alpha spectrometer. Results showed on spatially heterogeneous distribution of the Po and Po activity concentrations in M. procera and two interpolation maps were prepared. Activity concentrations of nuclides in dried caps of M. procera were in the range from 3.38 ± 0.41 to 16.70 ± 0.33 Bq∙Po ∙kg and from 5.11 ± 0.21 to 13.42 ± 0.30 Bq∙Pb ∙kg. Consumption of M. procera foraged in central and northern Poland should not contribute significantly to the annual effective radiation doses from Po and Pb due to amount of both nuclides accumulated by fungus in caps.
本文介绍了在伞菌（Macrolepiota procera）子实体中 Po 和 Pb 的积累和分布研究结果，以及由于两种放射性核素发射的高放射性衰变颗粒对人类消费者造成的风险。蘑菇是从波兰中部和北部的 16 个森林地区收集的。在对核素进行放射化学分离后，使用经过验证的方法和α谱仪对 Po 和 Pb 的活度浓度进行了测定。结果表明，Po 和 Po 活度浓度在 M. procera 中呈空间异质分布，并制备了两张插值图。M. procera 干燥菌盖中核素的活度浓度范围为 3.38±0.41 至 16.70±0.33 Bq·Po·kg 和 5.11±0.21 至 13.42±0.30 Bq·Pb·kg。由于真菌在菌盖中积累的两种核素数量，波兰中部和北部地区采集的 M. procera 的消费不会对 Po 和 Pb 的年有效辐射剂量产生显著影响。
