摘要
对广西两家使用南方离子吸附型稀土精矿作为原料的稀土分离企业的外围环境放射性水平进行调查,主要指标包括企业外围环境γ辐射空气吸收剂量率、空气中氡浓度、外排废水流出物、地表水和地下水、周围土壤、纳污河流监测断面底泥。调查结果表明,两家企业外围环境放射性水平在正常范围内。
The environmental radioactivity levels of two rare earth separation plants using Southern ion-adsorbed rare earth concentrates as raw materials in Guangxi were 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 levels are within the normal range.
