We have searched for lines of the radioactive element technetium (Tc) in spectrum Przybylski's star (HD101065). The nuclei this chemical are formed slow process capturing thermalized neutrons. possible Tc~I heavily blended. synthesized profile one resonance line at 4297.06 \AA~, which is also a part complex blend, and we arrived decision that it not visible (as was first noted by Ryabchikova), ...

Abstract. The present work investigates the fracturing behavior of an anisotropic layered geomaterial, known as Opalinus Clay (OPA). formation this rock is mainly related to a sedimentation process, where bedding planes correspond isotropy. OPA here studied because its good properties, primarily, low permeability and high adsorption capability, which make it perfect candidate for storage radioa...

Silver phosphate glasses have been investigated for the conditioning of radioactive iodine 129. Their disposal in a deep geological repository requires high chemical durability, and to improve this property, two crosslinking agents were examined here: Nb2O5 Bi2O3. In addition, some these glasses, 50 % phosphorus was replaced by molybdenum assess role glass former entities. The effect modificati...

Membrane assisted liquid extraction(MALE) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. The present contribution outlines the classification of membrane assisted ...

The problem of possible contamination of the Georgian territory by radioactive products in case of accident at the Armenian Nuclear Power Plant (ANPP) is studied. Radioactive substances transportation, diffusion and fallout are investigated by mathematical modelling. Some results of numerical calculations are presented. Key-Words: Mathematical modeling, radioactive pollution, Georgian territory

Acetylcarnitine and acylcarnitine are hydrolyzed by alkaline hydrolysis. The total carnitine is measured by incubation of the sample with 14CacetylCoA and carnitine acetyltransferase. The radioactive acetylcarnitine is separated from the unreacted radioactive acetylCoA using a Dowex 2 x 8 anion exchange column. The radioactive acetylcarnitine fraction is quantitated by counting in a liquid scin...

Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...
