Outline of Final Research Achievements

The adhesions of radiocesium to the surfaces of cherry (Cerasus x yedoensis 'Somei-yoshino') tree bark were studied in northern Fukushima Prefecture. The 137Cs concentration on the bark is related to the radiation dose rate map of November 5, 2011. The 137Cs concentrations at the branch internodes grown in 2010 were three times that in 2011 in the cherry trees. It was believed that only a few radiocesium concentrations would decrease because of rain and transfer to other tree parts from the bark because the percent of exchangeable 137Cs extracted from the bark was 0.35%. The majority of the 137Cs was in the bark; however, there was a small quantity of it in the wood and phloem of the cherry trees. Autoradiography of the radioactive pollution on the surface of the cherry tree bark displayed a random spot pattern. The radioactive spots decreased after decontamination by chipping and were transferred to the latex gloves after treatment of the contaminated bark.
