Megjegyzések:	An automatic water sampling unit was developed to monitor the radioactive emission (radiocarbon and othercorrosion and fission products) from nuclear facilities into the groundwater. Automatic sampling is based on the principal ofion exchange using built-in resin columns in the submerging samplers. In this way, even the short-term emissions can bedetected. According to our experiments, the 14C activity concentrations and the ?13C values of the samples made by the ionexchange method are systematically underestimated compared to the real values. The carbonate adsorption feature of the samplingunit was studied under laboratory and field conditions. For this purpose, a test method was developed. The observedsampling efficiencies and additionally some carbon contamination for the sampling method itself have to be taken into considerationwhen we estimate the amount of 14C contamination introduced into the groundwater from a nuclear facility. Therefore,a correction factor should be made for the 14C anion exchange sampling. With the help of this correction, the resultsconverge to the expected value.
