摘　　要：白云鄂博矿石中含有较高的天然放射性钍,在采矿、选矿、冶炼钢铁和稀土产品生产过程中,局部地区的环境受到了不同程度的影响。通过对包头市、白云鄂博地区开展航空γ能谱测量,在重点地区配合地面车载γ能谱测量和便携式γ能谱测量、土壤样品采集分析等方法,基本查明放射性污染源项、污染范围和污染程度,为该地区放射性环境影响评价提供基础资料和科学依据;同时,也取得了放射性污染调查航空γ能谱测量、车载γ能谱测量等技术成果。The ores in Bayan Obo deposit are rich in radioactive thorium,causing a certain radiological impact on some nearby places during mining and processing to a varying extent.A program of airborne gamma ray spectrometry,as well as carborne,in situ gamma ray spectrometry and sampling for laboratory gamma ray spectrometry in potentially contaminated area has been conducted.As a result,radioactive contamination source terms,areas and severity have been determined and served as basic data for assessment of environmental radiological impact resulting from the exploitation of Bayan Obo mine.In the meantime,the techniques of airborne,carborne,in situ gama ray spectrometry has been achieved.
