在美国华盛顿州的西雅图，对210 Pb的月大气通量进行了为期7年的观测。月降雨量与210 Pb沉降量之间存在正相关关系，但在相同降雨量下，210 Pb沉降量的年变化规律不同。210 Pb的年平均输入量为0.44 dpm/cm ~ 2，平均值的标准误差为± 0.24 dpm/cm ~ 2。210 Pb年通量的4.4倍的波动在本次调查中观察到。
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.
