An automatic analysis system was developed to analyze Strontium-90 ( $^{90}$ Sr) radioactivity in environmental sample for 2013-2015. Various kinds of ashed environmental samples were used in performance tests of the automatic system. These tests were successful without any system trouble. However, $^{90}$ Sr concentration had not been measured using the samples analyzed by the system. In this research, $^{90}$ Sr concentration in seaweed sample was compared by between the system's analysis and worker's one. Moreover, the system was improved in each analysis process.
