本文报道了切尔诺贝利事故后采自意大利东北部地区的普通食用菌中放射性核素的活度。漏斗杯伞、鸡油菌和凹柄牛肝菌中的含量最高。此外，还在同一地区采集了大量土壤样本。根据137 Cs/134 Cs的比率，可以区分真菌和土壤中来自切尔诺贝利事故前沉降物的放射性铯。给出了~（137）Cs和~（134）Cs的等值线分布图。在蘑菇中检测到的放射性与相应土壤的污染水平没有简单的关系。有些种类倾向于浓缩铯和银核素，而其他种类则对这些和其他核素几乎没有亲和力。并对该物种不同的行为特征提出了解释。
Radionuclide activities in common edible mushrooms, collected in northeast Italy following the Chernobyl accident, are reported. The highest levels were found in Clitocybe infundibuliformis, Cantharellus lutescens and Boletus cavipes. In addition, a large number of soil samples was collected in the same area. From the 137Cs/134Cs ratios, it was possible to differentiate the radiocesium contribution from pre-Chernobyl fallout in both fungi and soil. The contour maps for 137Cs and 134Cs distributions are reported. The radioactivity detected in the mushrooms is not related in a simple manner to the contamination level of the corresponding soil. Some species tend to concentrate cesium and silver nuclides, whilst others show little affinity for these and other nuclides. Explanations for the different behavioral characteristics of the species are suggested.
