- •
Study of spatial variation of ionic and stable 137Cs in the initial fallout of FDNPP.
- •
Japanese cedar leaves and male cones were good indicators for this evaluation.
- •
A higher proportion of ionic 137Cs was found distributed along eastern Fukushima.
- •
Variations in the ionic ratio of 137Cs affect its translocation in Japanese cedar.
- •
High uncertainties were found in the calculated values in some sampling sites.
