Estimation of critical loads for radiocaesium in Fennoscandia and Northwest Russia
The application of the critical loads methodology for radioactive contamination of Arctic and sub-arctic ecosystems, where natural and semi-natural food products are important components of the diet of many people, is proposed and discussed.The critical load is herein defined as the amount of radion...
