文摘
- •
137Cs concentration distribution was compared between two coniferous forest ecosystems in Southern Finland and Japan.
- •
The time needed to reach steady-state 137Cs activity after the fallout was estimated in a forest ecosystem in Finland.
- •
The vertical distribution of the 137Cs fallout was similar between the two forests.
- •
137Cs was still mobile in soil surface layers in the Finnish forest 27 years after the accident.
- •
Our results indicate that 137Cs remains in the internal cycle of the forest ecosystem for decades.
