| 中文摘要:本文介绍了地下水测年的CFC方法及其原理,并将这种方法实际应用于我国高放废物处置库预选区——甘肃北山地区的水文地质研究,结果表明,研究区内沟谷洼地浅部地下水的CFC年龄在15~26a,基岩裂隙浅部地下水多为不含CFC的老水与含CFC的新水的混合水。在描述了确定混合比方法的基础上,根据样品CFC含量计算了研究区地下水的混合比。与氚相比,CFC是目前年轻地下水测年更好的工具,具有更多的优越性。 |

| Abstract:CFCs are effective tools in the study of groundwater dating. In this paper, the method and principles of CFC compounds as groundwater dating tools are described, and the actual application of the method to hydrogeological research in the Beishan Potential Repository Site in Gansu Province for China's High Level Radioactive Waste Disposal is reported. The results indicate that the CFC age of shallow groundwater located in valley and depression is mainly from 15 to 26 years and the shallow fracture water is mostly mixed water of young CFC_containing water and old CFC_free water. Based on the description of the method for determination of mixing ratios, the mixing ratios of groundwater in the study area are calculated from the CFC concentration of groundwater samples. In comparison with tritium, CFC seems to be a better tool which possesses more advantages for young groundwater dating at present. |
