How are observed spontaneous fission
Vobecký, Miloslav
A brief contribution commemorates the discovery of one of the modes (types) of radioactive transformation (decay) of atomic nuclei.
Gold chemical vapor generation by tetrahydroborate reduction for AAS: Radiotracer efficiency study and characterization of gold species
Musil, Stanislav ; Arslan, Y. ; Kratzer, Jan ; Vobecký, Miloslav ; Benada, Oldřich ; Matoušek, Tomáš ; Rychlovský, P. ; Ataman, O. Y. ; Dědina, Jiří
The main objective was to assess the generation efficiency in the optimized method of chemical vapor generation of gold by means of 198,199Au radioindicator. We also intended to characterize the volatile Au species formed by tetrahydroborate reduction.
Chemické generování těkavých sloučenin stříbra pro potřeby AAS: studie účinnosti transportu pomocí radioizotopu .sup.111./sup.Ag a in-situ kolekce na křemenném povrchu
Musil, Stanislav ; Kratzer, Jan ; Vobecký, Miloslav ; Matoušek, Tomáš
The method of chemical vapour generation of silver by means of sodium tetrahydroborate was futher developed in order to minimize transport losses. The possibility of collection of volatile silver species directly in the atomizer is presented.
Kryogenní záchyt arsenu pro speciační analýzu arsenu technikou hydridového generování s detekcí atomovou absorpční spektrometrií
Svoboda, Milan ; Kratzer, Jan ; Vobecký, Miloslav ; Rychlovský, P. ; Dědina, Jiří
The general aim of this work was to contribute to further improvement of the method for complete speciation analysis of trivalent and pentavalent human metabolites of arsenic in complex biological matrices. The main target of this work was to investigate processes during the cryotrapping procedure and find optimum conditions.
The use of radioanalytical methods in studies of thyreotoxic effects of exogenous bromide
Pavelka, Stanislav ; Vobecký, Miloslav ; Babický, Arnošt
Very high intake of bromide in the rat dams in the course of lactation period caused a marked decrease in the iodine transfer through nmother´s milk to the suckling. Excessive bromide intake in the mothers caused a marked decrease in the body weight increments in their pups.
Determination of mercury and methylmercury in hair
Čejchanová, M. ; Wranová, K. ; Spěváčková, V. ; Korunová, Vlasta ; Vobecký, Miloslav
This article exactly describes the process of taking samples and their stocking. From the results it is obvious that the content of inorgatic mercury in hair is dependent on the exogeneous contamination and the amalgam tooth filling number. The result of mercury content in hair was 0.33 ug/g.

Marci and the group of nuclear chemistry of the Czech chemical society, in cooperation with the Technical University in Prague.
Chemické generování těkavých forem stříbra jako metoda vnášení vzorku pro atomovou absorpční spektrometrii
Musil, Stanislav ; Kratzer, Jan ; Vobecký, Miloslav ; Rychlovský, P. ; Matoušek, Tomáš
A method of silver chemical vapour generation as a sample introduction technique for analytical atomic spectrometry is presented. Optimization of reaction and atomization parametrs was carried out and the efficiency of the chemical vapour generation was studied by means of radiotracer experiments.
