Abstract


A liquid scintillation counting apparatus that enables highly accurate measurements of (super 14) C has been constructed at the Solar-Terrestrial Environment Laboratory, Nagoya University. The main aim of the project is high precision year-by-year measurements of the (super 14) C content in tree rings of an old cedar tree from Yaku Island, Japan. We present the results of (super 14) C measurements on tree rings from the Agematsu region for recent decades to confirm the validity of the system.
