| 内容記述 | Distributions of radiocesium (137Cs) and radioiodine (131I) in giant butterbur (Petasites japonicus) was studied to investigate translocation of these radionuclides. The concentration ratios (on dry weight basis) between petiole and leaf for the first samples (28 March 2011) showed about 0.2 for both isotopes, however, the ratio increased to ca 0.7 for 131I while that for 137Cs was ca. 0.4 by 5 May 2011. The newly emerged shoots showed the concentrations in between. For 137Cs, further monitoring was carried out and it was found that the concentration ratios increased to between 0.46-0.86 after 200 days or more from the first sampling date. The uptake process was mainly from soil after 210 days from the first sampling date, the concentration of radiocesium was usually low in petiole. | |||||
