  2. 16. Exploring phenomena that affect the fate and impact of radioactive materials in the blue mussel

    Author : Benedict Jaeschke; Clare Bradshaw; Andrew Turner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radioecology; ionising radiation; environmental protection; Mytilus edulis; bioaccumulation; dose-response; ecotoxicology; tritium; particle; hypoxia; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Current protection of the marine environment from radiation is based largely on measuring, estimating and modelling accumulation and impact(s) of radionuclides in a few marine species. Using a relevant marine organism, this thesis focusses on investigating some poorly described phenomena that could cause deviations from predicted measurements. READ MORE

  4. 17. Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours

    Author : Christina Swärd; Göteborgs universitet; []
    Keywords : Carcinoid; Endocrine pancreatic tumour; Neuroendocrine; Octreotide; Somatostatin receptor; Peptide receptor; Radionuclide therapy; Absorbed dose; Chromogranin A; Liver transplantation;

    Abstract : Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours Background. Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) originate from endocrine cells of the intestinal mucosa and pancreas. READ MORE

  5. 18. The Influence of Hydrogen on the Radiolytic Oxidation of UO2

    Author : Niklas Hansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; XPS; Dose-Rate; Radiolytic Oxidation; UO2; MOX; Hydrogen Effect;

    Abstract : Spent nuclear fuel from the nuclear fuel cycle contains radiotoxic nuclides which must be safely stored for over 100 000 years. The Swedish final repository concept, KBS-3, is based on engineered and geological barriers that prevent the nuclear fuel from coming in contact with groundwater, which is the most credible vector to transport the radionuclides into the biosphere.

  6. 19. Photon Dose Calculations in a Fluence-Based Treatment Planning System: Data Processing, Implementation and Validation

    Author : Lars Weber; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Nuclear medicine; Radiopharmaceutical technology; Radiofarmaceutisk teknik; Nukleärmedicin; radiobiology;

    Abstract : The accuracy of dose calculations for various aspects of a treatment planning system (TPS) using an energy fluence beam modelling has been evaluated. The investigated TPS uses a beam model, which separates the energy fluence into a number of sources in the treatment head. READ MORE

  7. 20. Methods for image-based dosimetry and radiobiological modelling in radionuclide therapy

    Author : Johan Gustafsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radionuclide therapy; dosimetry; biologically effective dose; 177Lu-DOTATATE;

    Abstract : In radionuclide therapy (RNT), radioactive pharmaceuticals are administered for therapeutic purposes. Dosimetry, i.e. the estimation of the absorbed dose to various targets, can potentially lead to a better understanding of the therapeutic effects in RNT and allow for individualization of the therapy.
