Abstract: The retrospective review of scientific investigations of the Belarus hydrosphere within the radioactively contaminated territories is presented for 1986-2005. The area under consideration occupies more than 35 000 km2 with contamination levels 37-1480 kBq/m2 for 137Cs and 22-111 kBq/m2 for 90Sr. Wide-range variations in average vertical velocity (0.11-2.66 cm/yr) and coefficient of quasidiffusion (0.01-1.4 cm2/yr) of radiocaesium migration in soils have been observed. A statistically significant tendency of decreasing with time the radionuclide migration parameters in automorphic soddy-podzolic soils within the over floodplain river terraces was revealed. The levels of groundwater contamination varied within 0.02-0.58 Bq/l for 137Cs and 0.02-0.18 Bq/l for 90Sr. The behavior of Chernobyl-derived 137Cs and 90Sr in hydrologically isolated bog systems within the catchment area of the Pripyat River as well as radionuclide pollution of the water fl ows of Dnieper, Pripyat, Sozh, Besed, Iput Rivers are considered. Dynamics of decreasing the average annual radionuclide activity concentrations and their variations during spring-autumn high water levels is demonstrated. Simplifi ed dynamic model for predicting the radionuclide activity concentrations in the river water following the large-scale radionuclide contamination is considered.

Keywords: buffering landscape, cesium, migration
Abstract: It is shown that migration (equally with decay) is a mechanism responsible for the buffering capacity of landscape with respect to radiocesium contamination. An approach is offered to determine the gradation of the buffering capacity and corresponding parameters of the migration models.

Keywords: plutonium, 238pu, 239pu, 240pu, 242pu, isotopes, soil
Abstract: The paper deals with the development of a highly sensitive method for determining plutonium isotopes (238Pu, 239Pu + 240Pu, 242Pu) in the solid samples of environmental objects with preliminary radiochemical preparation. The chosen conditions for preparation of samples permit effective separation of plutonium from mixing alpha-radiating radionuclides and allow plutonium to release in the radiochemically pure form to a sample to be calculated. Spectrometric measurements of the calculated samples and identification of isotopes were made on a “Progress-alpha” alpha-spectrometric unit having a silicon semiconductor detector. The developed procedure is rather reliable in identifying and estimating the content of major plutonium isotopes in the soil and bed deposits at their background values (1 Bc/kg or higher). The paper presents the results of analysis of samples of the soil selected during radioecological monitoring in the South-Western Okrug of Moscow, as well as the alpha-spectra obtained.

Title: Distribution of pre- and post-Chernobyl radiocaesium with particle size fractions of soils
Author: Pasquale Spezzano
Reference: Journal of Environmental Radioactivity, Volume 83, Issue 2, 2005, Pages 117-127
DOI: http://dx.doi.org/10.1016/j.jenvrad.2005.02.002
Keywords: Chernobyl fallout; Weapons fallout; Soil; Radiocaesium; Particle size distribution
Abstract: The association of radiocaesium with particle size fractions separated by sieving and settling from soils sampled eight years after the Chernobyl accident has been determined. The three size fractions were: 63 μm. 137Cs in the soil samples was associated essentially with the finer size fractions, which generally showed specific activities 3–5 times higher than the bulk samples.
Activity ratios of 134Cs/137Cs in the clay-sized fractions appear to be lower with respect to the corresponding values in bulk soil samples. This result indicates that some differences still exists in the particle size distribution between 137Cs originating from nuclear weapons, which has been in the soil for decades after fallout, and 137Cs coming from the Chernobyl accident, eight years after the deposition event. This behaviour could be related to “ageing” processes of radiocaesium in soils.
