The Long-Term Dynamics of the Particulate 137Cs Supply from Eroded Arable Slopes During the Post-Chernobyl Period [PDF]
ToxicsIn rural areas affected by Chernobyl, accelerated erosion has become a major source of particulate 137Cs in sediment load. The long-term dynamics of the activity concentration in eroded soil material transported from individual slope catchments can be ...

Concentrations of 137Cs in forest mushrooms and soil in southern Poland [PDF]
Journal of Veterinary ResearchSince 1986, Poland has been constantly contaminated with radioactive 137Cs, and before that, it experienced fallout like most of the world since nuclear bomb tests. As a result of radioactive fallout, vegetation and fungi acquired contamination.

The influence of sedimentary heterogeneity on the diffusion of radionuclides in the sandy facies of Opalinus Clay at the field scale [PDF]
Advances in Geosciences, 2022 Radionuclide migration in clay-rich formations is typically dominated by diffusion considering the low permeability of these formations. An accurate estimation of radionuclide migration in host rocks using numerical tools plays a key role in the safety ...

Law of Nuclide Migration in Clayey Rocks considering Diffusion and Fluid Transport
Frontiers in Earth Science, 2022 A core concern in the research on deep geological disposal of high-level radioactive waste is the migration of radionuclides in geological bodies. Most studies on radionuclide migration consider the role of only the rock fissures without incorporating ...

Comparison of 210Pb Age Models of Peat Cores Derived from the Arkhangelsk Region
Applied Sciences, 2023 Dating young peatlands using the 210Pb dating procedure is a challenging task. The traditional 210Pb age models assume an exponential decline in radioactivity in line with depth in the peat profile. Lead exhibits considerable migratory capacity in Arctic
