Effect of liming on transfer of 90Sr into fishAim of the studyThe project aims at assessing the effect of liming on transfer of 90Sr into fish and evaluates the usability of liming as a countermeasure in case of a radiological accident. ImplementationIn 1991 Finnish Game and Fisheries Research Institute conducted an experimental liming in a small acidified lake. The lake was divided into two parts and calcium carbonate was added in the other half. Both fish and water samples were collected from this lake during 1986–2006. STUK analyses 90Sr from these samples and investigates if liming decreases the 90Sr accumulation in fish. Results will provide new information about the usability of countermeasures in case of a radiological accident. Additionally, the effect of water chemistry, such as pH, on accumulation of 90Sr in fish will be evaluated. Dissemination and exploitation of the resultsThe results will be published as an article in international publication series. The results can be utilised improving the models describing transfer of radionuclides in the environment and assessing different countermeasures in case of a radiological accident.
