The cesium-137 soil erosion and soil redistribution technique has been largely used in cultivated lands (Zhang and Walling 2005; Saç and Içhedef 2015; Fulajtar et al. 2017). Its use in forest environments has been limited to a few areas that have experienced fires, as documented by Blake et al. ( 2009 ), Wallbrink et al. ( 2002 ), Kiss …

Near-surface sediments of the northern basin of the playa, Lake Tyrrell, were analysed for the fallout radioisotope 137 Cs (to 20 cm depth) and pollen grains (to 1 cm) and the salt-crust depth at each sampling site was measured. 137 Cs areal concentrations (MBq km −2) were found to have a highly significant (p < 0.001) negative …

We study the excitation redistribution from cesium 7P 1=2 or 7P 3=2 to neighboring energy levels by Black Body Radiation (BBR) and inter atomic collisions using pump-probe spectroscopy inside a vapor cell. At low vapor densities we measure redistribution of the initial, velocity-selected, atomic excitation by BBR.

The fallout cesium-137 has been widely used to generate spatial soil redistribution data. The objectives are to compare the soil redistribution patterns predicted using the cesium-137 technique and the Water Erosion Prediction Project (WEPP) model, and to diagnose potential shortcomings in the configuration and assumptions of the WEPP model, if ...

Redistribution of the fallout radionuclide cesium-137 was used to estimate net sediment redistribution on five near-level (slopes <2%) cultivated fields. Net sediment outputs averaged over the past 30 years were 0.8, 3.4, 6.1, 35.9, and 38.2 tons·ha1 year1 was assumed to be the major transporting agent, since slopes were below the critical angle …

Therefore radio-cesium redistribution is primarily in the sediment-sorbed form. Sediment deposition occurs on the flood plains within the river channels towards the eastern coastal area. Deposition also occurs on the beds of reservoirs, and curved or broad parts of rivers, and depressions on the land surface where surface water flow rates drop. ...

The simulation of the cesium redistribution during the vacuum phase for different inner wall temperatures showed that raising the temperature from 30 °C to 70 °C resulted in a more uniform distribution within the ion source chamber. This distribution results in a reduction in cesium in the surface areas with little plasma density.

Redistribution of cesium may change the oxygen poten- tial profile within the pellet, which, in turn, affects the chemical state of cesium and would play an important role at the severe fuel damage. Furthermore, cesium released onto the surface of pellets migrates axially to the cooler sinks of a fuel pin at burnups greater than 50 MWd/kg, and ...
