Abstract

We investigated the periodic changes in the 137Cs concentration of tea plants (new shoots, old leaves, twigs, branches, trunks and roots) cultivated in an ordinary tea field management style without pruning grown in Kanagawa Prefecture from May 25th, 2011 to July 25th, 2012. There was a tendency for the 137Cs concentration of old leaves, twigs and branches to be decreased. The decrease of the 137Cs concentration in the tea plants was caused by rainfall, loss of leaves from plucking and skiffing and defoliation. As no periodic changes of the 137Cs concentration were observed in trunks and roots, it was suggested that the 137Cs in the new shoots translocated from old leaves, twigs and branches. <br>Furthermore, it was considered that the transition of the 137Cs concentration of old leaves, twigs and branches under ordinary tea field management without pruning could be represented as an exponential function within days after 25 May 2011.
