It is called bomb effect. Correspondingly plant ^<14>C concentration also increased. In this study, ∆^<14>C recorded in leaves of Puya raimondii which distributed on Andes was investigated. Comparison between ∆^<14>C records of Puya raimondii and bomb ^<14>C curve of Southern Hemisphere assumed that all leaves flushed within 13-14 years., 第22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21(2009)年度報告}, pages = {75--79}, title = {南米の植物に残る核実験の記録}, volume = {21}, year = {2010} }
