Hot particles: characterization and behaviour in the environment
نویسندگان
چکیده
A coordinated research project initiated by the IAEA on “Radiochemical, chemical and physical characterization of radioactive particles in the environment” was conducted by a research group representing twelve countries (Brazil, Denmark, Finland, Hungary, Israel, Kazakhstan, Norway, Russian Federation, Spain, Ukraine, USA) and the European Commission Joint Research Centre Institute for Transuranium Elements, Germany. A significant fraction of radioactive contamination released into the environment is present in the form of localised radioactive aggregates which are composed of particle bound radionuclides, however the long-term ecological and health impact of particle bound radionuclides is not known. In addition there are no standard techniques for sampling “hot particles” nor exist any reference materials for validating analytical procedures.

Comparison Nanostructure Behaviour of Copper Species on the Silicamatrix Xerogels
The incorporation of copper species is synthesized in a silica matrix by the sol-gel method. We have doped copper ions and copper particles using two different copper sources: Cu(NO3)2.3H2O and copper particles chemically synthesized. We can prepare the particles of copper metallic, cuprous and cupric oxide and compare the synthesis and characterization copper species on the silica matrix. O...

متن کاملIsolation and Characterization of Hyperthermophilic Nanobacteria from a Hot Spring in Ardabil, Iran
ABSTRACT Background and Objective: Nanobacteria are nanometer-scale particles with different shapes, which have been a subject of debate in modern microbiology. They belong to a proposed class of living organisms, specifically cell-walled microorganisms with a size much smaller than the generally accepted lower limit for life. Since some microorganisms are ...
متن کاملSegregation Behaviour of Particles in Gas Solid Fluidized Beds at Elevated Pressure
A comprehensive mathematical model based on the discrete particle model and computational fluid dynamics was utilized to investigate mixing and segregation of particles in fluidized beds at high pressure. To quantify the extent of mixing in the bed, the Lacey mixing index was used. Simulations were carried out with different mass fractions of small particles at various pressures ranging from 1 ...
