摘　　要：基于武器部件化爆后核材料气溶胶的源项经验数据,运用流体动力学研究方法,建立了事故区域建筑物的有限元计算网格模型。分析了放射性气溶胶迁移、扩散以及分布规律,评估了核素沉降分布以及放射性沉降区人员的照射剂量水平。研究成果为进一步分析更加复杂和更加实际的受限混合流体的扩散规律,以及事故条件下核材料放射性气溶胶的应急处置与人员防护,提供了一定的指导意义。Based on the source data of nuclear weapons material aerosol components after explosion, the fluid dynamics method was used and the finite element model of accident areas buildings were established. The radioac- tive aerosols migration, diffusion and distribution of radionuclide deposition were studied. The distribution and radi- oactive fallout dose level area personnel were assessed. Research results can provide some guidances for the diffu- sion of the further analysis of more complex and more practical mixture fluid, as well as the emergency and accident conditions of nuclear material radioactive aerosol protection.
