In this paper, we investigate a procedure for radiocarbon determination in forest soil and slurry from lake sediments. The total carbon these samples can be both inorganic organic. Inorganic analyzed straightforward manner using the direct absorption method by sample acidification CO 2 capture. For organic carbon, hybrid wet-oxidation of followed absorption. To evaluate processes with potassium dichromate (K Cr O 7 ) permanganate (KMnO 4 ), performed several experiments different quantities...
The paper presents the results of pre-operational environmental monitoring program for Experimental Pilot Plant Tritium and Deuterium Separation. tritium baseline was established in surface water samples, air, precipitation, crops, fish, meat milk. also summarizes azeotropic distillation procedure used to extract from samples problems encountered during its use.
The hydrogen radioactive isotope, tritium, not only reflects seasonal variation in precipitation but also variations on a local level. To use this radioisotope authentication and geographical indication procedures, the tritium levels vines, grapes, wine were measured two forms: (1) tissue-free water (TFWT), free of plant or aqueous phase wine; (2) organically bound (OBT), organic part (as ethanol). This paper presents behavior vines from May to October produced harvested grapes for both...
ABSTRACT The CO 2 absorption and liquid scintillation counting (LSC) are methods used in radioactivity monitoring programs of nuclear facilities for 14 C measurements due to high number samples relatively expected level concentration. paper describes the chemical sample preparation applied a quality control material (IAEA-C3 Cellulose), order evaluate reproducibility method this type material. Consequently, experiments we two home-made cocktails, containing amines, 2-methoxyethylamine (MEA)...
ABSTRACT This paper presents radiocarbon ( 14 C) variations in the atmosphere from Ramnicu Valcea, Romania. The samples were collected vicinity of Experimental Pilot Plant for Tritium and Deuterium Separation (PESTD) Institute Cryogenics Isotopic Technologies (ICSI) placed about 10 km south Valcea city (Romania), Govora industrial area. facility is an experimental project national nuclear energy research program, which has aim developing technologies tritium separation heavy water. It should...
Abstract Diphenyldiazomethane has been photolyzed in substance at its melting point, 31.5 °C, using light of 546 nm wavelength filtered out from a mercury lamp. Under these conditions the quantum yield decomposition diphenyldiazomethane is about two. This can be explained by assuming intermediate appearance radical (C 6 H 5 ) 2 C:, and formation benzophenone azine.
The observables of the beta-decay branches to low-lying levels 186Os and 188Os nuclei have been calculated within framework a triaxial rotor model. two odd particles, proton neutron, are in different high-j shells ( pi h11/2 nu i13/2) treated as BCS quasiparticles moving deformed potential. A surface delta residual interaction hexadecapole deformation beta 4 also included. For decay ground states Os shapes spectra ft values satisfactorily predicted using only usual terms hadron current,...
Using the decoupling model for odd-odd-mass nuclei, extended to include in addition possibility of strong coupling, beta-decay observables 170Tm 1- 2+ and 0+ beta branches are calculated. The same studied isotopes 186Re 188Re using transitional nuclei. authors find that their theoretical results satisfactory agreement with experiment nuclei only if small induced terms considered axial current weak magnetism term vector current. However, these effects very difficult estimate rigorously.
