Transport of radionuclides by sea-ice and dense-water formed in western Kara Sea flaw leads
137 239,240.A transport assessment of particle-bound and dissolved artificial radionuclides Cs and Pu by sea-ice and dense-water formed in western Kara Sea flaw leads close to the Novaya Zemlya dumping sites is presented in this study. We both performed a ‘‘best estimate’ ’ based on available data,...
