Radiocesium concentrations in wild reindeer at Dovrefjell, Norway
Seasonal radiocesium concentrations varied about 6 times in wild reindeer following the Chernobyl accident, from 8 KBq/kg in August to 46 KBq/kg in March. These results agree with the predictions of earlier models. The within-season coefficient of variation was 52-62%. Between one half and 3/4 of th...
