Deposition of 137Cs and precipitation distribution in Vojvodina, Northern Serbia after the Chernobyl accident

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