Lead 210 and caesium 137 data of sediment core HE560_26-2

Data were established using the short-lived isotopes 210Pb and 137Cs. The 210Pb in recent marine sediments is of twofold origin, using planar-type HPGE gamma spectrometers.本数据集采用短寿命同位素铅-210（210Pb）与铯-137（137Cs）构建。现代海洋沉积物中的铅-210存在双重来源，相关检测采用平面型高纯锗γ能谱仪（planar-type HPGE gamma spectrometers）。
