1. The Chemistry of Plutonium Solubility
Abstract : When designing a repository for spent nuclear fuel it is necessary to assess the possibility that radionuclides will be transported from the repository by groundwater. A limiting factor for such transport is the solubility of any given radionuclide. READ MORE

2. On Weapons Plutonium in the Arctic Environment (Thule, Greenland)
Abstract : This thesis concerns a nuclear accident that occurred in the Thule (Pituffik) area, NW Greenland in 1968, called the Thule accident. Results are based on different analytical techniques, i.e. gamma spectrometry, alpha spectrometry, ICP-MS, SEM with EDX and different sediment models, i. READ MORE

3. Studies of actinides in a superanoxic fjord
Abstract : Water column and sediment profiles of plutonium, americium, thorium and uranium have been obtained in the superanoxic Framvaren fjord, southern Norway. The concentrations of bomb test fallout Pu, Am as well as 'dissolved' Th in the bottom water are the highest recorded in the marine environment. READ MORE

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

5. Surface Complexation Studies in An (Th, U(IV), Pu(VI)) Systems
Abstract : Two-phase systems containing an electrolyte solution and a suspended solid were studied. The common denominator for the three systems examined in this work is that they contain actinides (elements of atomic numbers between 89 and 103) in either the solid phase or as a sorbate. Experiments were done on simple oxides. READ MORE
