摘要
The correlation of Cs-137 specific activity profiles with the historical fallout sequence in the study region is essential in sediment cores dating using this technique. The authors of the referenced article considered 1965 the end of Cs-137 fallout in the study region, omitting the South Pacific nuclear test from 1966 to 1974, proved that generated the most intense Cs-137 fallout.
