Current status of the AMS facility at the Tono Geoscience Center of the Japan Atomic Energy Agency

The JAEA-AMS-TONO system is routinely used for 14C measurements at Tono Geoscience Center, Japan Atomic Energy Agency (JAEA) and applied to neotectonics and hydrogeology, in support of research on geosphere stability applicable to the long-term isolation of high-level radioactive waste. 10Be AMS has...

Description
Summary:The JAEA-AMS-TONO system is routinely used for 14C measurements at Tono Geoscience Center, Japan Atomic Energy Agency (JAEA) and applied to neotectonics and hydrogeology, in support of research on geosphere stability applicable to the long-term isolation of high-level radioactive waste. 10Be AMS has been developed for geochronological studies to estimate sedimentation rates and exposure age of basement rocks, incorporating a gas ionization detector with a large-volume gas absorber cell. Test measurements on 14C and 10Be reference materials show the system’s performance and suitability for application in the geosciences.
