| Abstract: | Using liquid scintillation counting (LSC) to determine the ratio of 79Se/78Se in the irradiated sample was reported. Firstly, the γ and β spectrum of irradiated sample was measured to find out the interferefering nuclide. Then, the irradiated sample was heated up to remove the interferefering nuclide from the sample as much as possible. At last, the activity 79Se was determined by LSC, and the ratio of 79Se/78Se was determined to be (5.44±0.23)×10－5. It provides reliable standard sample for AMS measurement. |
