Radionuclides in Northwest Pacific plain sediment

We collected three sediment cores in the Northwest Pacific plain in 2021 and 2022. Using with these cores, we measured radionuclides (210Pb and 226Ra). This dataset contains sampling site locations, 210Pb ,226Ra and excess 210Pb activities of these cores. These data are used for preparing figures, tables and the discussions in Zhu et al. (2024).本研究于2021年至2022年间在西北太平洋平原采集了三根沉积物岩芯。依托上述岩芯样品，我们对放射性核素（radionuclides）210Pb与226Ra开展了活度测定。本数据集包含各岩芯的采样点位坐标、210Pb、226Ra以及过剩210Pb（excess 210Pb）的活度数据。该数据集可用于编制Zhu等人（2024）研究中的图表、表格及讨论内容。
