钚气溶胶的形成机理

Abstract

Abstract: Nuclear science research, nuclear power plant accidents and nuclear terrorist attacks release plutonium aerosols, which are harmful to the public and environmental safety. Grasping the mechanism ofthe formation of plutonium aerosols is not only the theoretical basis for assessing and preventing the effects of radiation, but also an important prerequisitefor plutonium aerosol sampling and characterization. Based on the three modal distribution theories of aerosol particles, two control steps of gas phase nucleation and coagulation & aggregation in plutonium aerosol formation are summarized.The aerosolization of plutonium in different scenarios such as oxidation, combustion and high energy events is reviewed, including the development of chemicalprocess research, with a view to assisting subsequent efforts.

Key words: Pu aerosol, Oxidation, Combustion, Explosion, Formation mechanism
