1. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries
Abstract : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. READ MORE

2. Structural integrity of prestressed nuclear reactor containments
Abstract : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. READ MORE

3. Radiation tests of semiconductor detectors
Abstract : This thesis investigates the response of Gallium Arsenide (GaAs) detectors to ionizing irradiation. Detectors based on π-υ junction formed by deep level centers doping. READ MORE

4. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry
Abstract : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. READ MORE

5. Studies of Long-lived Radionuclides in the Environment - with Emphasis on 99Tc, 237Np and Pu Isotopes
Abstract : Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. READ MORE
