We performed micro-PIXE analysis for tea leaves which were grown with foliar absorption of Cs and Sr to clarify similarities or differences in Cs and Sr concentrations in them. The results have shown that Ca and Sr are accumulated in narrow areas like tiny dots in the leaves collected 3 days after the foliar absorption while Cs and K are almost uniformly distributed, indicating some common features in the elemental concentration among alkali earth metals.
