- •
Radionuclides in 16 freshwater fish species in Fukushima were analyzed.
- •
Low concentrations of 131I were detected in a small percentage of samples.
- •
Radiocesium contamination persisted in fish in contaminated rivers and lakes.
- •
Herbivorous and planktivorous fish with shorter longevity showed rapid 137Cs decrease.
- •
Carnivorous and omnivorous fish showed lagged 137Cs increase and gradual decrease.
