Transfer factors (TFs) of some selected radionuclides from ten different Japanese soils to radish have been studied by radiotracer experiments. The geometric mean values of TFs (on a wet weight basis) of radioactive Cs, Sr, Co, Mn and Zn for edible parts of radish (tuber) were 0.0090. 0.029, 0.00094, 0.0034 and 0.067, respectively. TFs for leaf were higher than those for tuber. The geometric mean values of leaf/tuber ratios were 4.1 for Cs, 4.9 for Sr, 1.6 for Co, 11 for Mn and 1.9 for Zn. Most of the Cs TFs obtained for andosol, which is the most common arable soil in Japan, were higher than those for the other soils. This might be due to the high concentrations of organic matter and alophen in andosol. The obtained TFs were compared to reference values of IAEA Technical Report 364.
通过放射性示踪实验研究了十种不同日本土壤中某些选定放射性核素向萝卜的转移因子(TFs)。萝卜可食用部分(块茎)中放射性铯(Cs)、锶(Sr)、钴(Co)、锰(Mn)和锌(Zn)的转移因子几何平均值(以湿重计)分别为0.0090、0.029、0.00094、0.0034和0.067。叶片的转移因子高于块茎。叶片/块茎比值的几何平均值,铯为4.1,锶为4.9,钴为1.6,锰为11,锌为1.9。在日本最常见的可耕地土壤安山土中获得的大多数铯转移因子高于其他土壤。这可能是由于安山土中有机质和阿洛芬的浓度较高。将获得的转移因子与国际原子能机构技术报告364的参考值进行了比较。
