摘要：

The downward velocity of Pb and Cs in undistrubted European forest soils is determined from the depth distribution of atmospheric Pb-210, and from the penetration depth of the bomb Cs peak in the soil. The downward velocity of Pb and Cs shows no correlation with soil type and pH. The downward migration of Pb and Cs is found to be due to an apparent downward movement of organic material, caused by the sedimentation of soil organic matter and subsequent turnover into CO2. Cs migration, however, shows an additional velocity component which is found to depend on the turnover rate of soil organic matter.
