Radioecology investigates the behavior of radioactive substances in the biosphere. Adequate research-based radioecological knowledge is needed in accidental situations (Chernobyl, Fukushima) and in estimating the risks of radioactive pollutants that occur in the environment in normal situations such as those originating from the entire nuclear fuel cycle from mining to final disposal of spent nuclear fuel.

Radioecological knowledge is important for assessing risks to both human health and wildlife species/ecosystems. Concerning human health, food is in most cases the main route of exposure to radionuclides. Nevertheless, there is increasing interest in the effects of ionizing radiation on non-human species as the available data is very limited.

In radioecological studies we focus on developing radioecological models based on improved theoretical and empirical understanding of uptake of radionuclides in organisms in terrestrial and aquatic ecosystems. The particular focus would be on key species in the food webs. We are also interested in assessment of radiation effects on wildlife by applying the most sensitive methods.
