Major Field of Science: | Natural Sciences | Field Category: | Chemical Sciences | Keywords: | Alpha radiation;Coastal waters;Ion exchange chromatography;Liquid scintillation counting;Radiation measurement;Radioactive contamination;Radiometry;Sea pollution | Issue Date: | Dec-2006 | Source: | Journal of Radioanalytical and Nuclear Chemistry. 2006, Volume 270, Issue 3, Pages 593-596 | Abstract: | Liquid scintillation counting of the alpha-radionuclides after pre-concentration by cation-exchange represents a simple and robust method for the determination of total alpha-radioactivity in seawater. The total efficiency and the minimum detectable activity were calculated to be 95% and 30 mBq, respectively, for a liter sample and 1000-minute measuring time. The method has been applied successfully for the determination of alpha-radioactivity in seawater from five different coastal areas in Cyprus. The average alpha-radioactivity and uranium concentration were found to be 124±8 mBq·1-1 and 3.2±0.2 μg·1-1, respectively. | URI: | https://hdl.handle.net/20.500.14279/11049 | ISSN: | 15882780 | DOI: | 10.1007/s10967-006-0466-1 | Rights: | © 2006 Akadémiai Kiadó. | Type: | Article | Affiliation : | University of Cyprus | Publication Type: | Peer Reviewed |
