The experiment was conducted to minimize the methods and chemical procedures ofthe existing maritime specimen radiostrontium analytic method. Fish specimen among the maritimespecimens were selected, and extraction chromatography and carbonate extraction chromatographyamong the chemical separation stages were executed. 85Sr radioactive standard was used for themeasurement of the retrieval rate, and the retrieval rates of extraction chromatography and carbonateextraction chromatography were 85.3±0.7% and 95.0±1.7%, respectively. The verification of eachanalytic method was executed by using 90Sr radioactive standard. As the results of verification, bothextraction chromatography and carbonate extraction chromatography were found to be within ±5%of the corresponding standards. Time taken for preliminary processing, including the ashing time, foreach analytic method was approximately 2 days and 2 hours as well as 2 days and 6 hours for extractionchromatography and carbonate extraction chromatography, respectively. It is anticipated that it can beutilized as the rapid radiostrontium analytic method in the future since it is possible to reduce the timetaken for the analysis to approximately 1/5~1/6 of that for the fuming nitric acid method, and to executethe analysis of more specimens within a short period of time.
