| Abstract: | The environmental radioactivity levels of two rare earth separation plants usingSouthern ion-adsorbed rare earth concentrates as raw materials in Guangxiwere investigated. The main indicators include the γ-radiation air absorbed dose rate, the concentration of radon in the air, as well as radioactivity levels in liquid effluents, surface water, ground water, surrounding soil and monitoring sections of sediment in receiving rivers. The results show that the levelsare within the normal range. |
