Behavior of long-lived radionuclides in the Danube river ecosystem in Serbia
(Journal of Radioanalytical and Nuclear Chemistry, 2006)
Radioactivity of water and sediments from the Danube river in its course through Serbia during 2001-2003 years has been tested by alpha- and gamma-ray spectrometry. Except for cesium originating from Chernobyl, the ...
Environmental impact of radioactive silver released from nuclear power plant
(Journal of Radioanalytical and Nuclear Chemistry, 2002)
Radioactive silver Ag-110m is not a fission product, but as a contaminant originating from Chernobyl, was registered in many European countries. The environmental impact of radioactive silver was specially expressed in the ...
Separation of tungsten and rhenium on alumina in dynamic conditions
(Journal of Radioanalytical and Nuclear Chemistry, 2007)
The separation of tungstate and perrhenate anions on alumina from aqueous solutions of sodium chloride was investigated in dynamic conditions. The breakthrough curves for W and Re as the function of the ratio of their ...
Comparison of some physicochemical and pharmacokinetical parameters of Tc-99m-PAH, Tc-99m-MAG(3) and I-131-OIH
(Journal of Radioanalytical and Nuclear Chemistry, 2002)
The purpose of this study was to compare some physicochemical characteristics as well as pharmacokinetic behavior of Tc-99m-PAH as a novel renal agent, with Tc-99m-MAG(3) and (OIH)-O-131. Tc-99m-PAH was prepared from ...
Sorption of tungsten on alumina in dynamic conditions
(Journal of Radioanalytical and Nuclear Chemistry, 2005)
The sorption of tungstate anions on alumina from aqueous solutions of sodium chloride was investigated in dynamic conditions. The breakthrough curves as the function of W and NaCl concentrations, pH and the flow rates were ...
Sorption of cesium on copper hexacyanoferrate/polymer/silica composites in batch and dynamic conditions
(Journal of Radioanalytical and Nuclear Chemistry, 2002)
The sorption of cesium ions from aqueous solutions on composite sorbents was investigated in static (by the batch method) and dynamic (on column) conditions. The composite sorbents consisted of copper hexacyanoferrate ...
Comparison of mathematical interpretation in radioactive waste leaching studies
(Journal of Radioanalytical and Nuclear Chemistry, 2003)
Transport phenomena involved in the leaching of a radioactive material from a concrete composite matrix into surrounding water are investigated using three methods based on theoretical equations. These are: a diffusion ...
Influence of natural sorbents on the immobilization of spent ion exchange resins in cement
(Journal of Radioanalytical and Nuclear Chemistry, 2006)
Leach characteristics of Cs-137 and Co-60 radionuclides from spent mix bead ion exchange resins and both ordinary Portland cement and cement mixed with two kind of natural sorbents (bentonite and clinoptilolite) have been ...
First results studying the transmutation of (129)I, (237)Np, (238)Pu, and (239)Pu in the irradiation of an extended (nat)U/Pb-assembly with 2.52 GeV deuterons
(Journal of Radioanalytical and Nuclear Chemistry, 2009)
An extended U/Pb-assembly was irradiated with an extracted beam of 2.52 GeV deuterons from the Nuclotron accelerator of the Laboratory of High Energies within the JINR in Dubna, Russia. The lay-out of this experiment and ...
Chemical and biological properties of verapamil labeled with technetium-99m: A potential myocardial imaging agents
(Journal of Radioanalytical and Nuclear Chemistry, 2002)
On the base of property to enter into myocardial cells as a calcium channel blocker, verapamil was labeled with technetium-99m in order to investigate the possibility to obtain new radiopharmaceutical for myocardial imaging. ...
