 note = {^<14>C abundances are measured across a weathering rind formed in Triassic calcareous sandstone. ^<14>C has not been detected by our sensitive AMS in the fresh sandstone, while about a half amount of the present ^<14>C is detected in the weathering rind of the sandstone. 14C is found to be a sensitive index of concrete weathering. The fresh concrete made from natural limestone does not contain any ^<14>C. Weathering in atmospheric condition will replace the dead carbon in the concrete with radiogenic ^<14>C and will be able to detect easily., 第20回名古屋大学年代測定総合研究センターシンポジウム平成19(2007)年度報告<第2部> Proceedings of the 20th symposiumon on Chronological Studies at the Nagoya University Center for Chronological Research\nin 2007 日時:平成20 (2008)年1月10日(木)～11日(金) 会場:名古屋大学野依記念学術交流館 Date:January10th-11th, 2008 Venue:Nagoya Uhiversity Noyori Conference Hall},
