DNA DAMAGE AND RADIOCESIUM IN CHANNEL CATFISH FROM CHERNOBYL

  • Title: DNA DAMAGE AND RADIOCESIUM IN CHANNEL CATFISH FROM CHERNOBYL

Keywords: Catfish, Chernobyl DNA damage, Micronuclei Radiocesium

Abstract: The explosion of the Chernobyl Nuclear Power Plant resulted in some of the most radioactively contaminated habitats on earth. Despite evacuation of all human inhabitants from the most contaminated areas, animals and plants continue to thrive in these areas. This study examines the levels of contamination and genetic damage associated with radiocesium in catfish (Ictalurus punctatus) from the cooling pond and a control site. In general, catfish from the cooling pond exhibit greater genetic damage, and the amount of damage is related to the concentration of radiocesium in individual fish. Genetic damage is primarily in the form of DNA strand breaks, with few micronuclei being observed in contaminated fish. The possible roles that acclimation and adaption play in the response to high levels of radiation exposure are discussed.

Sedimentation rates measurements in former channels of the upper Rhône river using Chernobyl 137Cs and 134Cs as tracers.

Keywords: Fluvial hydrosystem; Radionuclide; Sedimentation rate; Sediment organic carbon

Abstract: Former river channels are aquatic ecosystems with a different geomorphology generated by fluvial dynamics more or less linked to the main channel. They present different ecological successions to become terrestrial ecosystems and are thus supposed to have different sedimentation rates. The aim of this paper is to assess this sedimentation rate using radioactive tracer methodology commonly used in lake studies.

Main investigation results on the forest radioecology in the Kyshtym and Chernobyl accident zones.

  • Title: Main investigation results on the forest radioecology in the Kyshtym and Chernobyl accident zones.

Keywords:

Abstract: As a result of the long-term studies of radionuclide migration in forest ecosystems in zones of radioactive contamination after the Kyshtym and Chernobyl accidents, the following trends were revealed: (1) High retention capacity of stand canopy with respect to radioactive fallout. This leads to high doses absorbed by apical and leaf meristems, beta-radiation giving the main part of the dose; (2) Fast self-decontamination of crowns during the growth period and relatively slow decontamination in the phase of physiological rest, regardless of amount of atmospheric precipitation.

Dynamics of 137Cs in the forests of the 30-km zone around the Chernobyl nuclear power plant.

  • Title: Dynamics of 137Cs in the forests of the 30-km zone around the Chernobyl nuclear power plant.

Author: Mamikhin, S V / Tikhomirov, F A / Shcheglov, A I

Reference: The Science of the total environment, 193 (3), p.169-177, Jan 1997

doi:

Keywords: Radionuclides; Forest; Dynamics

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).

Radiocaesium concentration factors of Chernobyl-contaminated fish: a study of the influence of potassium, and “blind” testing of a previously developed model

Keywords: Radiocaesium; Fish; Chernobyl; Modelling

Abstract: The radiocaesium concentration factors (CF) of different fish species in 10 lakes in Russia, Belarus and Ukraine were measured between 6 and 11 yr after the Chernobyl accident. Clear inverse relations were observed between fish CF and lakewater K+ concentration.

Abstract: After the sudden fallout from the Chernobyl nuclear accident in 1986, activities and bioaccumulation factors of radiocaesium (137Cs, 134Cs) fluctuated strongly over several years before reaching quasi-equilibrium, with patterns significantly differing among organisms.

Keywords:

Abstract: The objectives of the Model Validation Committee were to collaborate with US and foreign scientists to collect, manage, and evaluate data for identifying critical research issues and data needs to support an integrated assessment of the Chernobyl nuclear accident; test environmental transport, human dosimetric, and health effects models against measured data to determine their efficacy in guiding decisions on protective actions and in estimating exposures to populations and individuals following a nuclear accident; and apply Chernobyl data to quantifications of key processes governing the environmental transport, fate and effects of radionuclides and other trace substances.

Keywords:

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.

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

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

Author: Agapkina, G I / Tikhomirov, F A

Reference: The Science of the total environment, 157 (1-3), p.267-273, Dec 1994

doi: 10.1016/S0265-931X(99)00037-5

Keywords:

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.
