Application of copper vapour lasers for controlling activity of uranium isotopes

Beryllium nanoparticles are generated upon ablation of a beryllium target in water by a copper vapour laser. The average size of single crystalline nanoparticles is . Ablation of a beryllium target in aqueous solutions of uranyl chloride leads to a significant (up to ) decrease in the gamma activity...

Beschreibung
Zusammenfassung:	Beryllium nanoparticles are generated upon ablation of a beryllium target in water by a copper vapour laser. The average size of single crystalline nanoparticles is . Ablation of a beryllium target in aqueous solutions of uranyl chloride leads to a significant (up to ) decrease in the gamma activity of radionuclides of the uranium-238 and uranium-235 series. Data on the recovery of the gamma activity of these nuclides to new steady-state values after laser irradiation are obtained. The possibility of application of copper vapour lasers for radioactive waste deactivation is discussed.
