For evaluating radioactivity of the deposit in the study area and studying the feasibility of applying the radioactive method, the authors measured the γ radiation dose rate of rocks and ores. Statistics show that the γ radiation dose rates of the bauxite vary in the range of (15.53~48.01)×10^-9 (C/kg)/h, with the average value being 24.37×10^-9 (C/kg)/h, whereas the γ radiation dose rates of other rocks and ores vary between 4×10^-9 (C/kg)/h and 8×10^-9 (C/kg)/h, suggesting that the bauxite has the strongest radiation in the deposit, which, however, is still much lower than the rated value of evaluation of human hygiene. It is considered that radioactive characteristics of China’s sedimentary bauxite deposits in ancient weathering crusts resemble the characteristics of this deposit, and that the significant difference between bauxite and other rocks provides the physical condition for applying the radioactive method to exploring bauxite deposits.
