Abstract
The activities of 239+240Pu, 238Pu, 241Am, 90Sr, 137Cs, 40K, 228Ac were measured as well as the activity ratios of 228Th to 232Th and 230Th to 232Th in samples of two rised peat profiles collected from Kościeliska Valley in the Western Tatra Mountains in 2002 and 2003. Results show some differences in the vertical distribution of examined radionuclides. Calculated cumulated deposition in the deeper profile is equal to 6.9±0.2 kBq/m2 (137Cs), 168±11 Bq/m 2 (239+240Pu), 4.3±0.8 Bq/m2 ( 238Pu), 33±3 Bq/m2 (241Am) and 607±11 Bq/m2 (90Sr). Therefore, it seems that radiostrontium was partially removed from the examined part of the profile. The peat grow-up rate was estimated from the position of the maxima of the vertical distribution of radiocesium and plutonium (6 to 8 mm/y), and from the determination of the vertical distribution of 210Pb (1.25 mm/y). The discrepancy seems to be due to the solubility of lead. © 2006 Akadémiai Kiadó.
