Radioactivity Distribution of the Fruit Trees Ascribable to Radioactive Fall Out(III):A Study on Peach and Grape Cultivated in South Fukushima

Abstract

The radioactivities of 134Cs and 137Cs in grape and peach trees and the soils where these trees were cultivated were measured in Fukushima prefecture In grape, the radioactivity in trees or soil was very low owing to cultivation in a plastic greenhouse In peach, though radioactivity in shoots, leaves, fruits or roots was low, that in 3 years-old branches, was high, especially at the bark The high radioactivity at outer side of the bark could be found by an imaging plate (author)
