Distributions of 210Pb, 228Th, and the fallout nuclides 239,240Pu and 3H in sedime-tn core from Bosten Lake have been measured. The sedimentation rates based on 210Pb, 228Th, and 239,210pu are 0.31 cm/yr, 0.26 cm/yr and 0.33 cm/yr, respectively.

• 作者测定了博斯腾湖沉积岩心~(210)Pb、~(228)Th和核试验释放核素~(239；240)Pu、~3H的分布；并据~(210)Pb、~(228)Th、~(239；240)Pu的结果估算湖泊的沉积速率；分别为0.；31cm/a；
