摘　　要：针对核电厂事故后环境修复过程产生的放射性污染土壤,采用MC法分析了污染土壤包装容器外表面100 mm处剂量率的影响因素,并基于包装容器外表面100 mm处剂量率大小建立了核电厂事故污染土壤中两种主要核素^(137)Cs和^(90)Sr同时存在时的快速分类方法,实现对污染土壤的快速筛分,减少核电厂事故需处理处置的放射性污染土壤量。Aiming at the radioactive contaminated soil generated during the environmental remediation process after the nuclear power plant accident,the MC method was used to analyze the influencing factors of the dose rate at 100 mm from the outer surface of the contaminated soil packaging container.And based on the dose rate at 100 mm of the outer surface of the packaging container,a rapid classification method for the coexistence of two main nuclides^(137)Cs and^(90)Sr in the contaminated soil of the nuclear power plant was established,so as to realize the rapid classification of the contaminated soil and reduce the amount of radioactively contaminated soil for disposal in the nuclear power plant accident.
