Abstract

The inert gas radioactive isotope Kr (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 Kr/Kr will be determined by an ATTA instrument. According to the atmospheric input curve of Kr, the Kr age of groundwater is determined. We conducted Kr analysis in three wells in Zhengding County on the plains in front of the Taihang Mountains, and made a comparison with tritium (H) method.

河北平原浅层含水层氪-85定年

惰性气体放射性同位素Kr(半衰期为10.74年)由于其稳定的物理和化学性质，是浅层地下水测年的理想示踪剂。在这种测年应用中，首先从现场地下水中提取溶解气体，然后从气体样品中分离氪，最后用ATTA仪器测定同位素丰度Kr/Kr。根据氪的大气输入曲线，确定了地下水的氪年龄。对太行山前平原正定县3口井进行了氪分析，并与氚(H)法进行了比较。
