Measurement of the natural ³⁶Cl and ²³⁶U in uranium mineral with accelerator mass spectrometry

摘要: The concentration of the natural ultra-trace radionuclides ³⁶Cl and ²³⁶U in the uranium depended on the neutron flux. In this article, a method for measuring ³⁶Cl and ²³⁶U in the same uranium mineral with accelerator mass spectrometry was developed in China Institute of Atomic Energy, providing a protocol of the potential application of ²³⁶U in uranium mining, environmental, and geological research. The two samples were from Guangxi and Shanxi province, China, and their ratios ³⁶Cl/Cl and ²³⁶U/²³⁸U were measured. More experimental data conduced to understand the natural nuclides in the uranium mineral. We plan to conduct more efforts on the research.
