抄録

The concentrations of <SUP>226</SUP>Ra in upland field crops (e. g., cabbage, leek, onion, potato. and so on) and associated soils collected from 45 locations throughout Japan were determined in order to obtain soil-to-crop transfer factors (TFs). Concentrations of <SUP>226</SUP>Ra in the soils collected in southwestern Japan were higher than those in northeastern Japan; however, no correlations between <SUP>226</SUP>Ra concentrations in crops and soils were observed. The TFs ranged from <1.1 × 10<SUP>-3</SUP> to 5.8 × 10<SUP>-2</SUP> with a geometric mean of 6.4 × 10<SUP>-3</SUP>. These data were within the 95% confidential range of TF-Ra for several crops as reported in the IAEA Technical Reports Series No. 364. Among the alkaline earth metals, TF-Ba was similar to TF-Ra.
