  4. 2. Radioimmunotherapy of Metastatic Disease - Studies of Alpha- and Beta-particle-Emitting Radionuclides in a Preclinical Model

    Author : Sophie Eriksson; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; Antibody therapy; Lutetium-177; Astatine-211; Syngeneic tumor model; Colon carcinoma; Metastases; Autoradiography;

    Abstract : In radioimmunotherapy, monoclonal antibodies (mAbs) are used as a targeting agent carrying a toxic payload consisting of radionuclides. This treatment allows the irradiation of small lesions, even on the microscopic level. In the present work, two radionuclides with different properties were used. READ MORE

  5. 3. Methods for localizing and quantifying radionuclide sources and deposition using in situ gamma spectrometry : Critical review of the peak-to-valley method based on experimental studies and applications in Georgia and Japan

    Author : Karl Östlund; Malmö Medicinsk strålningsfysik; []
    Keywords : In situ gamma spectrometry;

    Abstract : This thesis describes investigations made on mobile and stationary gammaspectrometry made both under laboratory conditions and in situ. The objective hasbeen to identify and quantify radionuclides in the form of point sources,contamination and widespread deposition in situations where the measurementgeometry is not known beforehand.

  6. 4. Redox Reactions of Uranium-Based Materials in Aqueous Systems and Under UHV Conditions. : Two models mimicking radiation-induced oxidation of spent nuclear fuel

    Author : Ghada El Jamal; Mats Jonsson; Christophe Jégou; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : The demand for clean electricity is a primary concern in Europe. Nuclear power isconsidered as a greenhouse gas-free technology for generation of electricity. However,compared to other energy sources, it generates a highly toxic waste.In Sweden, the long-term solution for the waste disposal issue is called the KBS-3 method. READ MORE

  7. 5. Dynamics of Spent Nuclear Fuel Dissolution : Impact of Catalysis, Matrix Composition and Time Evolution

    Author : Annika Carolin Maier; Mats Jonsson; Christophe Jégou; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : Worldwide, nuclear power produces a large portion of the electricity that we consume every day. While nuclear energy comes with certain advantages, waste originating from its use is of particular concern. READ MORE
