The application of stable isotope and radioisotopes to the radioactive hydrogeochemical prospecting for uranium

The study of stable isotopes and radioisotopes was conducted for recognizing radioactive water anomalies and their origin during the uranium hydrogeochemical prospecting, which is considered as an important problem for study. Three types of groundwater anomalies were determined, namely (1) local enrichment by leaching and evaporation; (2) water anomalies caused by uranium mineralization; (3) mixing of shallow water and deep-seated water, through the study of hydrogen and oxygen isotopes and tritium determination in Baochang area. And the altitude of recharge area was estimated to be 1796 meters. The excess of U-234 in groundwater indicates the possibility of uranium mineralization. The study of the isotope hydrology gives a new approach for the radioactive hydrogeochemical prospecting for uranium
