This chapter attempts to introduce the development of a radon sampling device for the investigation of the return air shaft of mines. Also, different radon measurement methods were compared, which were based on the investigation of the radon release and diffusion pattern in the return air shaft, alkaline (CO2 + O2) in situ leaching uranium and sulfuric acid in situ leaching uranium, as well as analysis on continuous distribution characteristics of environmental radon activity concentration. Additionally, comparative studies on the normalized radon release of various mining processes and aerosol radionuclide distribution of various uranium mining facilities were implemented. Finally, the radiation dose prediction evaluation and cumulative radiation dose evaluation based on effluent monitoring and environmental monitoring, respectively, together with normalized public dose evaluation are also presented.
