Samples of different species of mushrooms were collected in the forests contaminated by Chernobyl (ChNPP) accident fallout debris. Sampling sites were located at a distance of 5-200 km from Chernobyl NPP. Transfer factors (TF) for Cs-137 from soil to mushrooms varied from 12 to 5060 nCi kg-1/Ci km-2; TF variability depended on the distance from ChNPP, mushroom species and growth conditions. The highest concentrations of Cs-137 were observed in Paxillus involutus and Xerocomus badius. These species are suggested as bioindicators of radioactive contamination.
在受切尔诺贝利（ChNPP）事故沉降碎片污染的森林中采集了不同种类蘑菇的样本。采样地点距离切尔诺贝利核电站5至200公里。铯-137从土壤到蘑菇的转移因子（TF）在12至5060纳居里·千克-1/居里·公里-2之间变化；TF的变异性取决于与切尔诺贝利核电站的距离、蘑菇种类和生长条件。在卷缘桩菇和栗褐牛肝菌中观察到最高浓度的铯-137。建议将这些物种作为放射性污染的生物指示物。
