摘　　要：本文参考建设用地土壤污染状况调查的工作内容及程序,结合放射性核素污染特征及其在环境介质中的迁移规律等,归纳总结了一套受天然放射性核素污染场地土壤放射性调查的工作内容及程序,为土壤放射性污染调查提供参考。将土壤放射性污染调查分为第一阶段土壤放射性污染调查和第二阶段土壤放射性污染调查,调查内容包括资料收集、现场踏勘、现场采样与监测、室内分析、报告编制等,监测项目包括地表环境γ辐射剂量率,土壤及地下水中^(238)U、^(232)Th、^(226)Ra核素浓度。根据工作内容及程序对两个可能受天然放射性核素污染的场地土壤进行调查,以评价工业过程对工矿企业场地土壤中放射性核素浓度的影响。调查结果表明该调查的工作内容及程序可行。By referring to the work content and procedure of soil pollution investigation in construction land and combining with the characteristics of radionuclide pollution and its migration rule in environmental media,this paper summarizes a set of work content and procedure of soil radioactivity investigation in sites contaminated by natural radionuclides,providing reference for soil radioactive pollution investigation.The investigation of soil radioactive pollution is divided into the first stage and the second stage,including data collection,site exploration,site sampling and monitoring,indoor analysis,report compilation,etc.The monitoring items included the environmental gamma radiation dose rate on the surface and the concentration of ^(238)U,^(232)Th and ^(226)Ra nuclides in soil and groundwater.According to the work contents and procedures,the soil of two sites that may be contaminated by natural radionuclides was investigated to evaluate the impact of industrial processes on the concentration of radionuclides in the soil of industrial and mining enterprises.The investigation results show that the investigation contents and procedures are feasible.
