| Outline of Final Research Achievements |
A possible method for extend the radiocarbon dating range (50ka) is to enrich radiocarbon isotopically in sample. In this study, new system of the isotope enrichment by means of pressure swing adsorption was designed and examined for radiocarbon enrichment. During two-year research, we succeeded to enrich radiocarbon in CO gas form. It has been confirmed that this approach is a potential method for extension of radiocarbon dating range, but we still need more research for the practical application of this method.
