Abstrakt: Lichens are very useful for monitoring of the radionuclide deposition because having a high efficiency capturing the radionuclides from the atmospheric fallout. In the present work, 210 Po and 210 Pb deposition in some lichen species were determined using an alpha spectrometer. Different lichens were collected around Demirci-Manisa and investigated their uses as biomonitor for 210 Po and 210 Pb deposition. The highest activity concentrations for 210 Po and 210 Pb were detected in Neofuscelia pulla (898 Bq kg -1 and 1207 Bq kg -1 , respectively). The mean activities in the lichen species ranged from 164 to 584 Bq kg -1 for 210 Po and from 175 to 671 Bq kg -1 for 210 Pb. The activity ratios for 210 Po/ 210 Pb ranged from 0.75 to 1.57.
