In Japan, Radiocarbon dating has been increasingly applied for archaeological relics. The ^<14>C ages must be converted to the calendar ages for archaeological studies. In calibrating ^<14>C ages it is generally assumed that a constant atmospheric ^<14>C concentration prevails worldwide, and tree ring data of the Western resources, such as bristlecone pine in the U.S.A., have been used to calibrate dates for the Eastern, as well as for Japan. Calibration by original resources is highly required for more precise radiocarbon dating of Japanese archaeological relics. Dendrochronology for Japanese cypress and Japanese cedar has been pursued by The Nara National Cultural Properties Research Institute. The former extends to B.C. 317,and the latter extends to B.C. 420. A new-generation Tandetron accelerator mass spectrometer installed at Nagoya University is suitable to perform a detailed calibration of ^<14>C ages with dendrochronology since this system is expected to attain high precision (under 0.3%) and high performance (3000 samples per year). We aim at establishing radiocarbon calibration for the Yayoi and the Kofun periods., 第10回名古屋大学タンデトロン加速器質量分析計シンポジウム(平成9 (1997)年度)報告 「最新型タンデトロン加速器質量分析計(加速器年代測定システム)による高精度・高分解能14C年代測定の利用分野・方法の開拓(II)」}, pages = {120--124}, title = {ヒノキ・スギなどの年輪年代による炭素14年代の修正に関する研究計画}, volume = {9}, year = {1998} }
