The technology of radioactive aerosol capturing was the premise of radiochemical analysis of aerosol,helped to promote the development of aerosol radiochemical analysis.In this paper,by using a combination of different filtering materials and the construction of aerosol filter,radiochemical analysis aerosol sampling technique was discussed.Experiments show that:by the combination of sintered metal felt and high efficiency material,the efficiency can reach above 98%.The aerosol was generated by explosions of...
