Understanding the distribution of radionuclides from uranium mine tail gas into the surface atmosphere is one way of dealing with radioactive pollution, but the factors affecting the concentration distribution are considered insufficiently studied. This article looks into the structural characteristics of the exhaust shaft of a uranium mine and studied the effect of the cross-sectional shape (square or round) on radionuclide concentrations. We used numerical simulation to verify the significance and clarity of the impact. The results show that,...
