EPMA and mass spectrometry of soil and grass containing radioactivity from the nuclear accident at Chernobyl
Electron microprobe analysis and mass spectrometry results for topsoil and grass contaminated by nuclear fallout from the Chernobyl accident are presented. The grass contained 2.5 times more (137)Cs than the soil and most of this caesium was evidently incorporated in the plant tissue. Particles containing (238)U and (235)U were found in both the soil sample and the grass sample. Far more of these hot particles were present in the soil sample, however. The discovery of fuel particles has significance, because they may act as long-term reservoirs of radionuclides, slowly releasing their fission products over many years to the environment.
