用~（133）CsCl溶液处理日本柳杉叶部（柳杉）和科纳拉橡树（Quercus serrata）在野外条件下调查放射性铯是否可以通过叶片衰老从叶片转移到其他部位，以及这是否在树种之间存在差异。133 Cs在两个物种中转移到附近的叶片，而在科纳拉橡树中观察到转移到树枝的基部，但不是日本雪松这些结果表明，易位的放射性铯对木本分支可能是更突出的科纳拉橡树比日本雪松通过衰老的树叶。
133CsCl solution was applied to the foliage of Japanese cedar (Cryptomeria japonica) and Konara oak (Quercus serrata) under field conditions to investigate whether radiocesium could be translocated from the foliage to other parts through senescence of foliage, and whether this differs between tree species.133Cs was translocated to nearby foliage in both species, whereas translocation to the base of the branches was observed in Konara oak, but not in Japanese cedar. These results suggest that the translocation of radiocesium towards woody branches might be more prominent in Konara oak than in Japanese cedar through senescence of foliage.
