Measurement of atmospheric fluxes of radionuclides at a UK site using both direct (rain) and indirect (soils) methods

0
Direct measurements of radionuclide tracers are useful tools for correcting proxy fluxes that are subject to post depositional changes. An analytical methodology was designed for the measurement of 210Pb and 7Be in rainwater. Atmospheric inputs of the radionuclides to Cumbria (UK) were recorded. Rainwater fluxes were then compared with measurements from soil cores. The annual deposition from April 1997 to March 1998 of 210Pb and 7Be was 165 8 Bq m-2 and 3912 120 Bq m-2, respectively, compared to an indirect 210Pb flux of 148 7 Bq m-2 yr-1 calculated from soil core records.
