摘要：

To clarify the enrichment characteristics of uranium and radon in deep-buried geothermal water, 39 geothermal water samples with a buried depth of more than 800 m in the Kaifeng geothermal system in China were collected. According to the test results of uranium concentration, radon activity and other conventional chemical indicators of the water samples, the source of uranium and radon in geothermal water was obtained. Also, the influence of the redox environment, temperature and hydrochemical parameters on the occurrence characteristics of uranium and radon was analyzed. This study has indicative significance to the migration of geothermal water.
