Radiocarbon measurements of tree-ring samples collected in Vysoká pri Morave were compared with tree-ring data of the Žlkovce monitoring station situated 5km south-east from the Jaslovské Bohunice Nuclear Power Plant (NPP). Radiocarbon concentrations in Vysoká pri Morave and in Žlkovce 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 levels by fossil fuel CO emissions, was observed in both tree-ring data sets. The Vysoká pri Morave C data were during 1974-1995 systematically lower by about 50‰ than the Schauinsland (Germany) clean air reference values due to a regional fossil-fuel impact. However, after 1996 the Vysoká pri Morave C data were closer to the Schauinsland data due to lower CO emissions as a result of closing some of the heavy industry technologies in the region.
对在莫拉瓦河畔维索卡采集的树木年轮样本进行的放射性碳测量，与位于雅斯洛维采·博胡尼采核电站（NPP）东南5公里处的日尔科夫采监测站的树木年轮数据进行了比较。莫拉瓦河畔维索卡和日尔科夫采树木年轮中的放射性碳浓度分别以14.48±1.23年和17.96±1.97年的衰变常数呈指数下降，这与在其他放射性碳监测站获得的类似结果一致。在两个树木年轮数据集中都观察到了由化石燃料二氧化碳排放导致的碳水平稀释所代表的苏士效应。由于区域化石燃料的影响，1974 - 1995年期间，莫拉瓦河畔维索卡的碳数据系统地比德国绍因斯兰的清洁空气参考值低约50‰。然而，1996年之后，由于该地区一些重工业技术的关闭导致二氧化碳排放量降低，莫拉瓦河畔维索卡的碳数据更接近绍因斯兰的数据。
