| Abstract: | In order to determine the equilibrium coefficient of uranium ore sample, this article proposes a method by measuring γ-ray spectroscopy. According to the γ-ray decay and equilibrium law of uranium series, the content of radium and radon is calculated by the count of characteristic peaks in the γ-ray spectroscopy. Calculation formula is deduced for radium-radon equilibrium coefficient and the related parameters are discussed in detail. This method is simple and rapid, and can be used in on-site analysis of drilling core samples after further improved. |
