Abstract: Dynamics of the 137Cs content in the components of the forests in the 30-km zone around the Chernobyl nuclear power plant (NPP) in 1986-1994 are associated mainly with such factors as the size of radioactive particles in the fallout, ecosystem humidification and soil type, tree age. The influence of particle size was especially noticeable between 1986-1987 and was displayed by low biological availability of radionuclides in the near part of the zone (within the 10-km radius circle around the NPP) in comparison with more distant regions (within the 30-km radius circle).

Abstract: Vertical intrasoil flow within the 30-km zone of the Chernobyl nuclear power plant (ChNPP) was investigated by a lysimetric method in 1989-1990. The regularity of radionuclide migration within the flow has been found to be dependent on the contamination density, the type of radionuclide, and the type of ecosystem and depth.

- Title: Radionuclides in the liquid phase of the forest soils at the Chernobyl accident zone.

Abstract: The relative content (alpha) of 137Cs (1987-1991), 106Ru, 134Cs, 144Ce (1987) and the chemical speciation of radionuclides in the liquid phase of forest soils at different plots in the 30-km Chernobyl zone were studied. One year after the accident, substantial variations in the alpha-value between the different plots and a variation in alpha along the soil profile were observed due to unequal physico-chemical properties of nuclear fallout and soils. The alpha-value calculated for the total contaminated layer (alpha av) at different plots varied within relatively narrow limits.

Abstract: A number of assessment frameworks have been proposed to provide a mechanism to demonstrate protection of the environment from ionising radiation. Whilst some of these are being used for assessment purposes they have largely not been validated against field measurements.

- Title: Amount of 137Cs and 134Cs radionuclides in the Black Sea produced by the Chernobyl accident
Author: Eremeev, V.N. / Ivanov, L.M. / Kirwan, A.D., Jr / Margolina, T.M.
Reference: Journal of Environmental Radioactivity, 27 (1), p.49-63, Jan 1995

Keywords:
Abstract: Revised estimates of the amount of the nuclides 137Cs and 134Cs in the Black Sea resulting from the Chernobyl accident are reported. These results are at some variance with those reported by Chudinovskikh and Eremeev (Practical Ecology of Black Sea Areas, Naukova dumka, Kiev, 1990, pp. 46–56) and Nikitin et al. (Atomic Energy, 65 (1988) 134-7). The analysis here employs a spectral method whereas these other studies utilized less accurate methods. The study illustrates that the choice of numerical techniques for assimilating in-situ data into a model is important.

- Title: Chernobyl radionuclide distribution, migration, and environmental and agricultural impacts.

Abstract: The distribution and migration of radionuclides released into the environment following the Chernobyl accident in 1986 are described. The Chernobyl disaster resulted in the consumption of farm products containing radionuclides as a source of irradiation of the population due to the prevalence of a rural type of human nutrition in the affected region. This analysis demonstrates that if radiation standards protect humans, then biota are also adequately protected against ionizing radiation.
