První pokusy in-situ s radioaktivním indikátorem v žulovém kameni byly provedeny v podzemní laboratoři Josef v roce 2017. Experimenty, jejichž příprava trvala téměř čtyři roky, byly v České republice unikátní. Experimenty tohoto typu hrají klíčovou roli při ověřování numerických modelů migrace radionuklidů v hostitelském prostředí hlubinného úložiš...

Laser-induced breakdown detection was performed to monitor the nanoparticles in an aqueous solution by means of a two-dimensional optical imaging method. To verify the relationship between the particle size and the optical image of a laser-induced plasma, we investigated the characteristics of its spatial distribution corresponding to the number of...

The present investigation deals with how aquatic hydroxy aluminosilicate (HAS) colloids are generated in nature via co-nucleation of Si and Al in the presence of humic acid and moreover how trivalent actinides are integrated into the process. For the experiment, Am-241 (5 x 10(-8) M) is introduced into a colloid forming mother solution where compet...

A two-dimensional optical imaging method is presented for monitoring the laser-induced breakdown events of aqueous nanoparticles. The method is based on measuring the light intensity distribution of plasma from spatially resolved breakdown events. The number of laser breakdown events as a function of the emission intensity follows the Gaussian dist...

CdSe/ZnS quantum dots (QDs) coated with mercaptoacetic acid (MAA) in an anqueous solution are investigated by means of highly sensitive laser-induced breakdown detection (LIBD). In particular, a size distribution analysis of QDs dispersed in ultra pure water is performed as a function of time until a steady state is reached. Freshly prepared CdSe/Z...
