Abstract:

The results of 210Pb measurements in the lake sediment core from Antarctica are reported: the relative specific activities of 210Pb in the lake sediment were found to decrease exponentially with the depth in the study area; the sedimentation rate of the lake is about 0.072 cm/a. This paper shows that 210Pb method is applicable to Antarctic lake sediment ,and during the 1960's the atmospheric nuclear tests have an effect on the rate of 210Pb deposition in Antarctica.

Key words: Antarctica, Great Wall Station, lake sediment core, 210Pb method
