Environmental Radiocesium in Subarctic and Arctic Alaska Following Chernobyl
Radiocesium (134Cs and 137Cs) concentrations were measured in soil, plant and wildlife samples from subarctic to arctic Alaska. Concentrations of 137Cs ranged from below detectable or low levels in whale and fish samples to as high as 242 Bq/kg in lichen. For all potential human food items, the radi...
