Abstrakt

Radiocarbon measurements of tree-ring samples collected in Vysoka pri Morave were compared with tree-ring data of the Zlkovce monitoring station situated 5 km south-east from the Jaslovske Bohunice Nuclear Power Plant (NPP). Radiocarbon concentrations in Vysoka pri Morave and in Zlkovce tree rings were decreasing exponentially with decay constants of 14.48 +/- 1.23 y and 17.96 +/- 1.97 y, respectively, in agreement with similar results obtained at other radiocarbon stations. The Suess effect, represented by a dilution in C-14 levels by fossil fuel CO2 emissions, was observed in both tree-ring data sets. The Vysoka pri Morave C-14 data were during 1974-1995 systematically lower by about 50%o than the Schauinsland (Germany) clean air reference values due to a regional fossil-fuel impact. However, after 1996 the Vysoka pri Morave C-14 data were closer to the Schauinsland data due to lower CO2 emissions as a result of closing some of the heavy industry technologies in the region.
