| Outline of Final Research Achievements |
In this research, we aimed to establish the next-generation low-background technology early, combining the know-how of the low-background technologies that has been accumulated in small underground experimental groups in Japan so far. We aimed to realize the cooperation beyond the experiment groups with a keyword of “Micro Becquerel”. We worked on activities such as organizing topical workshops regularly to maintain technical cooperation. We also developed new radiation removal technologies and new high-sensitivity radioactivity measurement techniques. We realized the target sensitivities on some of these techniques. We also maintained our own radiation database to accumulate and share these know-how.
