Description

Movement and distribution of radiocaesium in peach tree was studied. The radiocaesium distributed on branches most, which branches were 1, 2 or 3 years old. With the observation of tissues of trunk, the highest radiocaesium concentration was measured at the bark, which was higher than that of soil surface. The radiocaesium concentration was drastically low in the wood part. However, the total amount of radiocaesium of wood was as the same level as that of the bark. About 20% of radiocaesium in the tree was estimated to be removed as fruits and leaves.
