Measurement of 210Pb atmospheric flux in the Pacific Northwest

|February 1, 1985
Abstract:
Monthly atmospheric flux of 210Pb in Seattle, WA, has been measured over a period of 7 yr. Direct correlation exists between monthly rainfall and the 210Pb deposition; however, for the same amount of rainfall the 210Pb deposition varies from year to year. The mean annual input of 210Pb is 0.44 dpm/cm2 and the standard error of the mean is +/- 0.24 dpm/cm2. A 4.4-fold fluctuation in the 210Pb annual flux was observed during this investigation.
