Abstract
The aim of this study was to determine the level of radionuclide concentration in sediment cores in two different water ecosystems; one closed and one open. Based on this data the changes in these ecosystems were interpreted. Two sediment cores from the Dobczyce reservoir and the Smreczynski Staw Lake were collected and divided into 1 cm thick sub-samples. The samples were air dried and homogenized. The Cs-137 and Pb-210 (Pb-210(sup), Pb-210(total), Pb-210(uns)) concentrations were measured using gamma and alpha spectrometry. Results showed that the Cs-137 concentration in the Dobczyce reservoir is lower than in the Smreczynski Staw Lake. Total Pb-210 concentration in the Dobczyce reservoir was around 70 Bq kg(-1) and in the Smreczynski Staw Lake was about 500 or 1,200 Bq kg(-1) with the decreasing tendency in the sediment core. Sediments are very important constituents of water ecosystems. In spite of the young age of the Dobczyce reservoir, the Cs-137 and Pb-210 radionuclides were very useful in understanding of the processes which have taken place in these ecosystems. The estimated sedimentation rate indicated such processes as regular sedimentation, mixing of sediments or floods. In the Smreczynski Staw Lake the changes have reflected the changes which took place in the Tatra Mountains.
