abstract = {The inert gas radioactive isotope 85Kr (with a half-life of 10.74 years), due to its stable physical and chemical properties, is an ideal tracer for shallow groundwater dating. In such a dating application, first the dissolved gas is extracted from groundwater in the field, then krypton is separated from the gas sample, and finally the isotopic abundance 85Kr/Kr will be determined by an ATTA instrument. According to the atmospheric input curve of 85Kr, the 85Kr age of groundwater is determined. We conducted 85Kr analysis in three wells in Zhengding County on the plains in front of the Taihang Mountains, and made a comparison with tritium (3H) method.}
