  1. 21. Studies on the Gamma Radiation Environment in Sweden with Special Reference to 137Cs

    Författare :Sara Almgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gamma radiation; caesium; 137Cs; deposition; migration; precipitation; in situ; CDE; NWF; Chernobyl; soil sampling; field measurements; dose measurements; dose rate; TLD; natural radiation; Kriging;

    Sammanfattning : Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case of fallout from nuclear weapons (NWF) or accidents, knowledge and monitoring of external gamma radiation and radionuclide concentrations in the environment is important.

  2. 22. Human Metabolism and Ecological Transfer of Radioactive Caesium

    Författare :Christopher Rääf; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; committed effective dose; aggregate transfer; ecological half-time; equivalent biological half-time; urianry excretion; radiocaesium; body burden; Environmental health; Miljömedicin; creatinine-normalisation; potassium-normalisation;

    Sammanfattning : The whole-body content of radiocaesium was measured in a South-Swedish urban group of people residing in the city of Lund (55.7°N, 13.2°E) between 1960 and 1994. LÄS MER

  3. 23. High-sensitivity Radioactive Xenon Monitoring and High-accuracy Neutron-proton Scattering Measurements

    Författare :Cecilia Johansson; Jan Blomgren; Nils Olsson; Allena Opper; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Monte Carlo simulations; MCNP; xenon detection; detector response; neutron detection; elastic scattering; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : Two aspects of applied nuclear physics have been studied in this thesis; Monte Carlo simulations for high-sensitivity monitoring of radioactive xenon and high-accuracy neutron-proton scattering measurements for neutron physics applications and fundamental physics. The Monte Carlo simulations have been performed for two systems for detection of radioactive xenon, using the MCNP code. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 25. Drömmen om en gränslös fred : Världsmedborgarrörelsens reaktopi, 1949-1968

    Författare :Jenny Gustafsson; Rebecka Lettevall; Henrik Bohlin; Anton Jansson; Södertörns högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; Världsmedborgarrörelsen the World Citizen Movement ; citizen of the world; mondialist; mondialism; cosmopolitanism; pacifism; -ism; temporal orientation; reactopia; Hannah Arendt; conceptual history; peace; masculinity; Historical Studies; Historiska studier;

    Sammanfattning : In postwar France, a new movement – Citoyens du Monde – emerged with the aim to unite people across the world around the political target of achieving world peace through dissolving the national borders and establishing a worldwide society. In 1949, Världsmedborgarrörelsen (the World Citizen Movement) was established in Sweden as the 21st branch of the movement and represented the new ism mondialism. LÄS MER
