Summary:Radionuclide analysis of sea water is necessary to monitor environmental contamination due to the radioactive substances from nuclear facilities. However, it is difficult to analyze the nuclides promptly with the conventional method of coprecipitation during emergencies because the method requires long precipitation times. In this study, an effective concentration method with ultrasonic nebulization was suggested for sea water samples. When a sea water sample of 40 L was concentrated, 30 h was required with the conventional method, whereas it took less than 11 h with the suggested method. The validity of the suggested method was verified by gamma-ray spectroscopy.
