In this research, the concentration of {sup 137}Cs 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 {sup 137}Cs, and the transfer factor was determined. The radiocesium content of the examined fruit bodies ranged from 2.5 Bq kg{sup {minus}1} to 33.3 Bq kg{sup {minus}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. 19 refs., 1 fig., 4 tabs.
