| The Application of Shallow Groundwater 3H-3He Dating Technique to Shijiazhuang City |
| The 3H-3He dating method is based on the principle that 3He concentration increases and 3H concentration decreases with the continual radioactive decay of tritium. This technique can well replace the tritium method in dating.With the financial support by the Nitional NSFC to the project-"The Application of shallow groundwater 3H-3He dating technique to hydrogeology", and based on the actual geological and hydrogeological conditions as well as previous studies in Shijiazhuang area, the authors collected water sam-ples from some representative wells. The 3H-3He ages of the shallow groundwater were determined through calculation of the test re-sult. These data show a consistent changing regularity with the tritium ages dated in 1982. From north to suth the ages of shallow groundwater gradually increase, with the oldest sample being in the southeast. Along the Hutuo River the ages are rather yong, and this is attributed to the recharge by the rivers in recent years. The application of the 3H-3He dating method to Shijiazhuang shallow groundwater proves to be very satisfactory. |
