| Outline of Final Research Achievements |
The purpose was enhancement of reliability for the performance of Po-210/Pb-210 analysis in the fish samples, and the establishment of comparability. First, the performance of published method was verified. From the results, the method indicated the quantitative recovery. Therefore, the standard operation procedure was produced based on the method. Based on the preliminary results, the dried bonito powder and the dried sardine powder were used for the interlaboratory comparison for Po-210/Pb-210 analysis. Three laboratories were participated on the comparison. The standard operation procedure and these dried fish powder sample were distributed to the participants. As a result, no significant difference was observed in the measured values by the participant. It was demonstrated that the validity of the standard operation procedure. Furthermore it was also demonstrate that Japanese laboratories have high analytical performance.
