摘　　要：为了加强矿产资源开采过程中放射性污染防治和辐射安全监管,掌握新疆矿产资源的放射性水平及特征,基于新疆1095家矿产资源企业普查结果,采用相关性与回归分析方法研究了矿产资源放射性水平及相关性特征。调查和研究得出:煤矿和铁矿矿产资源中3家企业物料-产品-固体废物中放射性核素含量高于1Bq/g,需纳入伴生放射性辐射环境管理范畴;固体废物中^(238)U和^(226)Ra与环境γ辐射剂量率的相关性高,表明矿产资源中主要伴生放射性核素为U和Ra。建议深入开展新疆煤矿和铁矿开采过程中伴生放射性核素赋存形态和分布规律研究,为评估环境和人体健康的辐射影响提供科学依据。To strengthen the prevention and control of radioactive pollution and radiation safety supervision in the exploitation process of mineral resources,and master the radioactive level and characteristics of mineral resources in Xinjiang,the correlation and regression analysis methods were used to study the radioactivity level and correlation characteristics of mineral resources in this paper based on the census results of 1095 mineral resources enterprises in Xinjiang.The correlation and regression analysis method was used to characterize the level and correlation of radioactivity in mineral resources.The results of the survey and study showed that the radionuclide content in the materials-products-solid wastes of three enterprises of coal and iron ore mines was higher than 1 Bq/g,which needed to be included in the scope of the management of the accompanying radioactivity;the correlation of ^(238)U and ^(226)Ra in the solid wastes with the ambient gamma dose rate was high,which indicated that the main accompanying radionuclides in the mineral resources were U and Ra.It is recommended to carry out an in-depth research on the accumulation pattern and distribution pattern of associated radionuclides in the process of coal and iron ore mining in Xinjiang,so as to provide a scientific basis for assessing the radiation impact on the environment and human health.
