210Pb和226Ra浓度随土壤深度的变化曲线用于确定从大气到地球表面的210Pb通量。结果为1.6 dpm cm−2yr−1。讨论了获取210Pb通量的其他方法。取值范围为0.53 ~ 2。北温带为0 dpm Cm−2yr−1。大陆值的估计值为0.8至2.0 dpm cm−2 yr−1，海洋值为0.53至1.0 dpm cm−2 yr−1。
210Pb and 226Ra concentrations versus soil depth profiles are used to determine the 210Pb flux from the atmosphere to the earth's surface. A value of 1.6 dpm cm−2yr−1 is obtained. Other methods of obtaining the 210Pb flux are discussed. Values range from 0.53 to 2. 0 dpm Cm−2yr−1 for the north temperate zone. Estimates of continental values range from 0.8 to 2.0 dpm cm−2 yr−1 and oceanic values from 0.53 to 1.0 dpm cm−2 yr−1.
