| 内容記述 | Due to the accident of Fukushima Daiichi Nuclear Power Plants (FDNPP) occurred on 11 March, 2011, some areas were contaminated with radionuclides. Since one year has been almost passed, we can find largely released, long-lived radionuclides in the terrestrial environment, that is, Cs-134 and Cs-137. The behavior in forests is of interest because large areas are covered by forest in Japan. In this study, we focused on bamboo forest, which is commonly found in Asian countries. Since Japanese use young bamboo shoot as a food materials and bamboo stems as various craftwork products, radiocesium behaviors in bamboo forests are of interest. We collected stems, leaves, shoots, litter, and soil samples of a bamboo forest (Ibaraki Prefecture) on 8 May, 2012 to see the distribution about 2 months after the large radionuclide releases from FDNPP. The results showed that most radiocesium was on bamboo body and litter layers; the concentrations of Cs-137 in twigs, leaves and litter samples were 0.9, 6.4 and 9.6 kBq/kg-wet, respectively. However, the concentration in soil was 0.5 kg/kg-dry, possibly because of the interception effect by the litter layer. The young bamboo shoots contained some radiocesium due to translocation from old bamboo trees. About 30% of radiocesium was removed from the young bamboo shoot by boiling. |
