uptake, soil-to-plant concentration ratios of radioiodine from soil to
agricultural crops are needed and so we carried out radiotracer experiments.
The mean values of concentration ratio (on a wet weight basis) of radioiodine
from soil to edible parts of crops in podzol were as follows: lentil,
0.054; pea, 0.012; wheat, 0.040 and red bean, 0.068. The mean values of
the radioiodine concentrations in plant parts of red bean, lentil, wheat
and pea (on a wet weight basis) were 4.32, 3.43, 2.64 and 1.0 kBq kg-1,
respectively. We also studied the distribution of the radioiodine in the
crops. There was a tendency for the concentration ratio of stem to be
higher than those of root and leaves. A very high concentration ratio
was found for root of red bean; because this plant was studied at a growth
stage different from that of the other plants. The data obtained in this
study should be useful in assessing the behavior of long-lived 129I
