This study investigated the variations in 137Cs concentrations in the fruits and leaves of persimmon trees, which had been affected by radioactive cesium for several years. The trees were divided into lateral or main branches, and 137Cs concentrations of fruits and leaves in the branches were measured. The 137Cs concentration differed among the fruits of the branches of the same tree, and the difference in 137Cs concentration in the fruits of each branch was confirmed for multiple years. A difference in 137Cs concentration of approximately ten times was found between the fruits of each branch on the same tree. In addition, a correlation was found between 137Cs concentrations in fruits and leaves. These results suggest that a difference might exist in the 137Cs concentration of each branch of the tree at the time of fallout in 2011, and it was considered that the difference might persist.
