摘要
A number of five species of macromycetes were collected during 2008 on Bistrita Valley in order to study the transfer of Ra-226 and Cs-137 radionuclides form substrate in the corresponding macromycetes. The soil pollution with Cs-137 was evidenced in the substrate corresponding to the Stropharia coronilla but not its translocation. For the other samples, Ra-226 coming from the uranium decay chain (often present in the rocks from the region) was detected by gamma-spectroscopy, all the values being below of the maximum admitted one. The obtained results were confirmed by FT-IR spectroscopy, the band presented at 910 cm(-1) being assigned to the asymmetric stretching vibration of the dioxouranium ions.
