| Outline of Final Research Achievements |
The method of generating radioactive aerosol using neutron-irradiated uranium has been developed. Using this device, it was clarified that differences in the properties of attached radioactive substances contribute more to the generation efficiency of radioactive solution aerosol particles than the chemical composition and concentration of solution aerosol particles.
The method to identify uranium-containing particles in the environment by combining heavy liquid separation with the fission track method has been also developed. In order to confirm the effectiveness of this method, we tried to analyze environmental samples that might contain uranium-containing particles and indirectly detected uranium-containing particles by detecting cluster of fission tracks on a solid-state detector.
