1. Transport of Radionuclides and Colloid Through Quartz Sand Columns
Abstract : Studies of the transport of radionuclides in the geosphere are one of the main tasks for performance assessment of a nuclear waste repository. A possible enhanced transport path for the radionuclides is the formation and transport of non-depositing colloids with a high affinity for radionuclides. READ MORE

2. Determining food web transfer of radionuclides in marine benthic ecosystems
Abstract : Food web interactions are vital in any functioning ecosystem and facilitate transfer of energy and nutrients between trophic levels. Unfortunately, they also facilitate transfer of contaminants such as anthropogenic radionuclides found in effluents from nuclear power plants (NPPs). READ MORE

3. Activity concentrations of radionuclides in energy production from peat, wood chips and straw
Abstract : In this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. READ MORE

4. Radionuclides in the Baltic Sea : Ecosystem models and experiments on transport and fate
Abstract : Manmade radionuclides have been introduced to the environment for almost a century. The main source has been the nuclear weapons testing programmes, but accidental releases from the nuclear power production industries have also contributed. The risk to humans from potential releases from nuclear facilities is evaluated in safety assessments. READ MORE

5. Element transport in aquatic ecosystems – Modelling general and element-specific mechanisms
Abstract : Radionuclides are widely used in energy production and medical, military and industrial applications. Thus, understanding the behaviour of radionuclides which have been or may be released into ecosystems is important for human and environmental risk assessment. READ MORE
