摘　　要：以包钢白云鄂博矿区为研究对象,对稀土矿开采的气态流出物排放造成的辐射环境影响进行了调查与评价。评价结果表明,虽然矿山生产所致的辐射影响低于我国矿产资源开发利用的公众个人有效剂量限值1 mSv/a,但是已对当地局部辐射环境质量造成了影响,导致当地居民所受剂量明显升高。为了改善当地的辐射环境质量,提出了应选取适宜的覆盖材料对废渣场、排土场尽快进行覆盖治理,新的废渣场及排土场的选址应尽量远离白云鄂博矿区城区,进一步减少开采及运输过程中的粉尘排放等建议。Taking Bayan Obo mining area of Baotou Iron and Steel Company as a typical case,the radiation environmental impact caused by the gas effluent emission from rare earth mining was investigated and evaluated.The evaluation results show that it has caused significant impact on the surrounding residents,although still lower than the limit of personal effective dose(1 mSv/a).As to improving the local radiation environmental quality,some measures should be taken as follows.Suitable covering materials should be selected to cover the waste slag yards and dumps as soon as possible.The locations of the new waste slag yards and dump yards should be kept as far away from the urban area of Bayan Obo mining area as possible.The dust emission during mining and transportation should be further reduced.
