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

In view of the extensive use of foraminifers for the pollution monitoring especially their unmatched utility in deciphering the temporal variation in the type and concentration of pollutants at a given location, the literature dealing with the application of foraminifers for pollution studies has been reviewed. The pollution monitoring through foraminifers started with attribution of peculiar f...

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...

The intravenous administration of emulsified fat in concentrations suitable for nutritional purposes is not applicable for clinical use because an emulsion stabilizer free of undesirable effects has not yet been developed. Pending the availability of a satisfactory stabilizer, the possibility of parenteral administration of fat by other routes deserves further exploration. Data reported on the ...

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...

effect of scale on the hydrodynamics of gas-solid fluidized beds was investigated in two fluidized beds of 152 mm and 78 mm in diameter.  air at room temperature was used as the fluidizing gas in the bed of sand particles. the radioactive particle tracking (rpt) technique was employed to obtain the instantaneous positions of the particles at every 20 ms of the experiments. these data were used ...

background: radon (222rn) measurement in the residential environments is very important because of its effecting on human health and causing cancer in the respiratory system. 222rn is individually responsible for half of the natural radiation received in humans and influences on human by breathing. hence, this study was undertaken to access the 222rn level in the dormitories of kerman universit...

introduction: skin dose and depth dose distribution of some beta sources that can contaminate skin or protective clothing covering the skin have been calculated using varskin2. materials and methods: in this research, absorbed dose to skin and depth dose from the skin surface have been calculated for 90sr/90y, 147pm, 32p beta emitter radioisotopes by using input parameters: activity of source, ...

During the last decades research all over the world has highlighted the deleterious effects of pollution on respiratory health of adults and children. Nevertheless, air pollution still represents a significant threat to health. Children are more sensitive than adults to pollutants for several factors: increased respiration relative to body size; physiologic immaturity of respiratory and immunol...
