Description

An aerosol collection system consisting of a high-frequency induction furnace and a cascade impactor has been developed to study properties of the metallic radioactive aerosol particles formed at high temperature. A pure carbon crucible was used for induction heating in the furnace. In this work, the collection system was applied to activated aluminum metal to measure particle size distribution of radionuclide-bearing aerosol particles generated from the molten aluminum. The aluminum sample was activated in a high-energy proton accelerator facility. Clean aerosol-free condition was attained up to 1,850℃ in the furnace by preheating of the crucible under argon atmosphere. The activated aluminum sample was melt at 1,850℃ and the aerosol particles were collected in the argon atmosphere. The impactor analysis showed that 22Na-bearing aluminum particles were smaller than non-radioactive aluminum particles. (author)
