Abstract

The present study follows the extent of translocation radioactivity from the substrates of the Crucea uranium mining area to the macromycetes spontaneously occurred during June–October 2008. To this end, radioactivity measurements (gross α + β and 137Cs) on both macromycetes and their substrates were made. The resultants obtained were confirmed by FT-IR spectroscopy, evidencing the presence of characteristic bands around of 910 cm−1, corresponding to the asymmetric stretching vibration of the uranyl unit and to the interaction between the UO2 2+ ions and the group belonging to various cellular components.
