AB  - Activity concentration of natural radionuclides and Cs-137 were studied in leaves of the deciduous trees. In the spring and autumn season, leaves were collected in the area of normal BACKGROUND:  radiation levels represented by city parks in a multi-year period (2002-2012). Measurements by means of gamma-ray spectrometry showed Ra-226 and (210)pb seasonal accumulation in leaves, while U-238 and U-235 could be detected only in autumn. Difference between seasons was not found significant for K-40 and Cs-137. The study of radionuclides transfer factors was conducted by analyzing its relationships with basic soil properties at the beginning and the end of the vegetation period.

AB  - n The present paper focuses on the determination of radiological characteristics of cultivated chernozem soil and crops from long-term field experiments, taking into account the importance of distribution and transfer of radionuclides in the soil-plant system, especially in agricultural cropland. The investigation was performed on the experimental fields where maize, winter wheat, and rapeseed were cultivated. Analysis of radioactivity included determination of the gross alpha and beta activity as a screening method, as well as the activities of the following radiouclides: natural (Pb-210, U-235, U-238, Ra-226, Th-232, K-40, Be-7) and artificial (Sr-90 and Cs-137). The activities of natural and artificial (Cs-137) radionuclides were determined by gamma spectrometry, while the artificial radionuclide Sr-90 was determined by a radiochemical analytical method. Based on the obtained results for the specific activity of K-40, Cs-137, and Sr-90, accumulation factors for these radionuclides were calculated in order to estimate transfer of radionuclides from soil to crops. The results of performed analyses showed that there is no increase of radioactivity that could endanger the food production through the grown crops.
