Factors controlling ~7Be and ~210Pb atmospheric deposition as revealed by sampling individual rain events in the region of Geneva, Switzerland

摘要

Bulk atmospheric deposition of ~7Be and ~210Pb has been measured at Versoix, close to Geneva, Switzerland. Collectors were continuously deployed from November 1997 through November 1998 for periods from 1 to 22 days depending on the frequency of rain. The Activities of ~7Be and ~210Pb integrated over the sampling interval were moderately well Correlated with rainfall (r~2 of 0.66 and 0.55, respectively; P<0.001) and well correlated one With the other (r~2 of 0.91; p<0.001).
