Abstract: The impact of environmental radiation on a decommissioned uranium mine in Guangxi Province was conducted with a series of relevant analyses. The results showed that the levels of gamma absorbed dose rate, radon exhalation rate, and natural radionuclide concentrations in soil and surface water were lower than the national decommissioning management limits, suggesting the effectiveness of the decommissioning treatment.

Key words: uranium mine, decommissioning treatment, environmental monitoring, dose limits
