文摘

Radiocesium, tritium and radiocarbon showed elevated levels in seawater of the western North Pacific. The water column inventories of 137Cs and 3H were 2.7 ± 0.4 and 0.3 ± 0.2 PBq, respectively. The radiocarbon levels were by about 9% above the global fallout background. Released radionuclides will be useful in future oceanographic and climate studies.
