| Popis: | There is a dilemma whether the Chernobyl accident is the main source of this anthropogenic radionuclide in the region of Vojvodina, Northern Province of Serbia. The difference compared to the other dominant source of radiocaesium in the environment, the nuclear weapon tests, is lying in the local character of contamination due to accidents, which implies it's highly dependent on meteorological parameters, such as precipitation and wind in the area at that time. According to published data, the average value of surface contamination by radiocaesium on the territory of the former Yugoslavia after the Chernobyl accident was several times higher than the estimated contamination by nuclear testing (1945–1963). The main aim of this research is to explore possible correlations of the spatial distribution of precipitation from April 1986 to December 1987 with the deposition of radiocaesium in the surface soil to justify this claim in the absence of data on caesium deposition before the Chernobyl accident for the Vojvodina region. The database of 137Cs content in Vojvodina soil and precipitation for this region during the timeframe of interest were used. From a total of 245 precipitation stations in Vojvodina, 164 to 244 precipitation stations were selected for analysis in conditionals from different time scale aspects and data validation. The best correlation between amounts of total precipitation and 137Cs content in surface soil obtained for two rainy periods 2nd-5th and 7th-21st May 1986. Further cluster analysis separated four different regions according to 137Cs deposition and precipitation for the mentioned rainy period which could be applied in the field of soil erosion assessment on the local and regional level. © 2020 Elsevier Ltd |
