Abstract

Japanese cedar leaves from Iwaki, Fukushima were analyzed for carbon, cesium and iodine isotopic compositions before and after the 2011 nuclear accident. The Δ¹⁴C values reflect ambient atmospheric ¹⁴C concentrations during the year the leaves were sampled/defoliated, and also previous year(s). The elevated ¹²⁹I and ^134,137Cs concentrations are attributed to direct exposure to the radioactive fallout for the pre-fallout-expended leaves and to internal translocation from older parts of the tree for post-fallout-expended leaves. ¹³⁴Cs/¹³⁷Cs and ¹²⁹I/¹³⁷Cs activity ratios suggest insignificant isotopic and elemental fractionation during translocation. However, fractionation between radioiodine and radiocesium is significant during transportation from the source.
