Abstract
Two peat profiles were collected in a peat bog located in Southern Poland and their geochronology were determined using Pb-210, Pu-238,Pu-239+240 and Cs-137 radiometric techniques. The Pb-210 chronologies were established using the constant rate of supply model (CRS) and are in good agreement with the Pu isotopes and Cs-137 time markers. Maximum activities of Pu isotopes were found at a depth corresponding to the early 1960s, which is the period characterized by the maximum nuclear weapon tests. The results showed that the Pb-210 method is the most accurate technique for the determination age and accumulation rate of a peat. The next part of this study calculated linear accumulation rates by analyzing Pu-238,Pu-239+240 and Cs-137 vertical distributions in the profiles. Activities of fallout isotopes were also measured in plants covering the peatland. The highest activities of Cs-137 and Pb-210 were found in Calluna vulgaris samples, and Pu239+24 were found only in two samples (C vulgaris and leaves of Oxycoccus quadripelatus).
