摘　　要：卫宁北山地区矿产资源丰富,这些矿产资源可能伴生高于规定水平的天然放射性物质,在生产利用过程中,天然放射性核素也将随之迁移、浓缩富集和扩散,其产品、废渣石等也将对环境及人体造成一定的辐射危害,因此针对该地区15个目标矿山进行环境放射性现场检测,获得其γ辐射剂量率水平及空气氡浓度水平现状,并对部分矿山进行取样分析,最终评估各矿山的辐射环境现状,总体上各矿山的辐射水平均超过当地环境本底,有3处矿山的辐射现状明显超过规范限值,应加强辐射监管。The Weining North Mountain area is full of mineral resources.These mineral resources may be involved in natural radioactive substances may be above the specified levels,and natural radionuclides will also migrate,concentrate and diffuse in the process of production and utilization.Its products or waste residue stone and so on will also cause certain radioactive hazards to the environment and human body.Therefore,environmental radioactivity detection was conducted in 15 target mines in this area.The current situation of gamma radiation dose rate and air radon concentration level was obtained.Sampling analysis was undertaken in some mines.The present situation of the radiation environment in each mine was evaluated at the same time.On the whole,the radiation level of all mines exceeds the local environmental background.The radiation status of three mines obviously exceeds the standard limit.So radiation supervision should be strengthened.
