Possibilities of using lead 210 as an atmospheric tracer

International audience The high sensitivity of the lead 210 measurement through the polonium 210 enables to date the neve layers of the Antarctic continent. Thus, appear some correlations between the concentration of lead 210 in the snow and the solar activity. The study of the atmospheric concentra...

Description
Summary:International audience The high sensitivity of the lead 210 measurement through the polonium 210 enables to date the neve layers of the Antarctic continent. Thus, appear some correlations between the concentration of lead 210 in the snow and the solar activity. The study of the atmospheric concentration of lead 210 above the oceans having proved the stratospheric origin of this nuclide in these regions, the former correlations are therefore due to a possible action of the sun's corpuscular radiations on the stratosphere-troposphere transfers.
