In this research, the concentration of 137Cs in the fruit bodies of the Tuber species T. magnatum Pico, T. borchii Vitt., T. aestivum Vitt., and T. excavatum Vitt. collected in three different regions of Italy was determined. The values obtained have been compared to the soil concentration of 137Cs, and the transfer factor was determined. The radiocesium content of the examined fruit bodies ranged from 2.5 Bq kg(-1) to 33.3 Bq kg(-1) fresh weight; the median transfer factor values of the four species ranged between 0.06 and 0.6. Our findings indicate that the radiocesium level in truffles from these regions of Italy is generally low, and, thus, their consumption is not of radiological concern. The results may suggest certain hypotheses as to the mechanisms involved in radiocesium uptake in these fungi.
在本研究中，测定了在意大利三个不同地区采集的白松露（Tuber magnatum Pico）、勃氏块菌（Tuber borchii Vitt.）、夏块菌（Tuber aestivum Vitt.）和凹陷块菌（Tuber excavatum Vitt.）子实体中¹³⁷Cs的浓度。将所得值与¹³⁷Cs的土壤浓度进行了比较，并确定了转移因子。所检测子实体的放射性铯含量在2.5 Bq kg⁻¹至33.3 Bq kg⁻¹鲜重之间；这四个物种的转移因子中位数在0.06至0.6之间。我们的研究结果表明，来自意大利这些地区的块菌中的放射性铯水平普遍较低，因此，食用这些块菌不存在放射性方面的担忧。这些结果可能为这些真菌中放射性铯吸收所涉及的机制提出某些假设。
