  2. 1. Rapid analysis of actinide isotopes using quadrupole ICP-MS for emergency preparedness and environmental monitoring

    Author : Christina Greis; Stefan Karlsson; Bert Allard; Anders Düker; Håkan Pettersson; Gi-Hoon Hong; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quadrupole ICP-MS; actinides; plutonium; preparedness; NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : Transuranium elements in the environment are mainly derived from nuclear weapons testing and the nuclear fuel cycle. Of growing concern are illicit nuclear trafficking and the threat of terror acts. READ MORE

  4. 2. On the Environmental Relevance of Platinum Group Elements

    Author : Sebastien Rauch; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platinum; ICP-MS; automobile emission; catalyst ageing; palladium; laser ablation; urban particles; bioaccumulation; rhodium;

    Abstract : It has recently been demonstrated that platinum group elements (PGE) are released from automobile catalysts into the environment, raising concern over ecological and human health risks. However, there is still a lack of knowledge regarding the dispersion and transformation of PGE in the environment and it is therefore difficult to assess potential risks. READ MORE

  5. 3. Development and Applications of some Radioanalytical Procedures: Analysis of β- and α-Emitting Radionuclides Using Radiometric and ICP-MS Detection Methods

    Author : Henrik Ramebäck; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; plutonium; 90Sr; curium; uranium; 99Tc; bentonite clay; analysis; UO2 fuel; leaching; americium; neptunium;

    Abstract : Analyses of radionuclides are important in environmental monitoring and in research. However, as in the analysis of many other species, interferences may be a problem. In a-spectrometric detection, 238Pu interferes with 241Am, owing to their similar decay energies. READ MORE
