- •
Both the 137Cs concentrations in green and dead foliar parts decreased exponentially over time.
- •
The 137Cs concentrations were always higher in dead parts than in green parts.
- •
Few weathering effect could be observed after early phase but internal translocation to newly emerging tissues.
- •
The correlation between 137Cs and K was clearly demonstrated in age classified foliar parts.
- •
Translocation of 137Cs would cease considerably earlier than the cessation of K translocation.
