Accumulation and translocation peculiarities of Cs-137 and K-40 in the soil - plant system

摘要

Long-term investigations (1996-2008) were conducted into the Cs-137 and K-40 in the soil of forests, swamps and meadows in different regions of Lithuania, as well as in the plants growing in these media. The Cs-137 and K-40 activity concentrations, the Cs-137/K-40 activity concentration ratio and accumulation, and translocation in the system, i.e. from the soil to plant roots to above-ground plant part of these radionuclides, were evaluated after gamma-spectrometric measurements using a high purity germanium (HPGe) detector.
