Radionuclides and microelements in natural waters in the zone of a uranium-vanadium deposit (Republic of Karelia) (English)

 

Author: Lukin A.A., Mel’nik N.A.

Reference: Gazette “Water Resources”, 2006

ISSN: 0097-8087

DOI: 10.1134/S009780780601009X

Keywords: radionuclides, water, soil, fish, concentration of uranium and vanadium

Abstract: The results of studies performed in the area of a uranium-vanadium deposit are used to characterize the concentration and distribution of microelements and radionuclides in water, soil, and fish. The exposure rate on the surface of the examined samples is found to be equal to 15�20 �r/h, i.e., to lie at the background level, which means that these samples are not an external radiation hazard for population. Concentrations of U and V in water somewhat greater than background values were recorded, though they are lower than MAC for fishery water bodies. The collected data show that a delicate equilibrium has formed in this territory, although the hydrochemical characteristics have not changed within the recent 40 years, and radionuclide content of water, soil, bottom sediments, and fish are at an extremely low level.

Lake fish as the main contributor of internal dose to lakeshore residents in the Chernobyl contaminated area

Title: Lake fish as the main contributor of internal dose to lakeshore residents in the Chernobyl contaminated area

Author: I.G Travnikova, A.N Bazjukin, G.Ja Bruk, V.N Shutov, M.I Balonov, L Skuterud, H Mehli, P Strand

Reference: Journal of Environmental Radioactivity, Volume 77, Issue 1, 2004, Pages 63-75

DOI: http://dx.doi.org/10.1016/j.jenvrad.2004.03.003

Keywords: Chernobyl; 137Cs; Lake; Internal exposure

Abstract: Two field expeditions in 1996 studied 137Cs intake patterns and its content in the bodies of adult residents from the village Kozhany in the Bryansk region, Russia, located on the shore of a drainless peat lake in an area subjected to significant radioactive contamination after the 1986 Chernobyl accident. The 137Cs contents in lake water and fish were two orders of magnitude greater than in local rivers and flow-through lakes, 10 years after Chernobyl radioactive contamination, and remain stable. The 137Cs content in lake fish and a mixture of forest mushrooms was between approximately 10–20 kBq/kg, which exceeded the temporary Russian permissible levels for these products by a factor of 20–40. Consumption of lake fish gave the main contribution to internal doses (40–50%) for Kozhany village inhabitants Simple countermeasures, such as Prussian blue doses for dairy cows and pre-boiling mushrooms and fish before cooking, halved the 137Cs internal dose to inhabitants, even 10 years after the radioactive fallout.

Decision making framework for application of forest countermeasures in the long term after the Chernobyl accident

Title: Decision making framework for application of forest countermeasures in the long term after the Chernobyl accident

Author: S.V. Fesenko, G. Voigt, S.I. Spiridonov, I.A. Gontarenko

Reference: Journal of Environmental Radioactivity, Volume 82, Issue 2, 2005, Pages 143-166

DOI: http://dx.doi.org/10.1016/j.jenvrad.2004.10.014

Keywords: Chernobyl accident; Forest countermeasures; 137Cs; Decision making

Abstract: After the ChNPP accident a very large part of the territories covered by natural and artificial forests are contaminated with long-lived radionuclides, especially 137Cs. To protect people against exposure associated with forest contamination in the most affected regions of the NIS countries, countermeasures have been developed and recommended for the forest management. The paper presents a decision making framework to optimise forest countermeasures in the long term after the ChNPP accident. The approach presented is based on the analysis of the main exposure pathways and application of radiological, socio-economical and ecological criteria for the selection of optimal countermeasures strategies. Because of the diversity of these criteria modern decision support technologies based on multi-attributive analysis were applied. The results of the application of this approach are presented in a selected study area (Novozybkov district, Bryansk region, Russian Federation). The results prove and emphasize the need for a flexible technique to provide the optimised forest countermeasures taking into account radioecological, social and economic features of contaminated forests.

Author: W.R. Schell, I. Linkov, V. Rimkevich, O. Chistic, A. Lutsko, A.M. Dvornik, T.A. Zhuchenko

Reference: Science of The Total Environment, Volume 180, Issue 3, 23 February 1996, Pages 229-240

DOI: http://dx.doi.org/10.1016/0048-9697(95)04946-0

Keywords: Chernobyl; Forest; Radionuclide contamination; Forest ecosystem modeling; Forest sampling

Abstract: Radiologically-contaminated forest and natural ecosystems contribute significantly to the human radiation dose in the intermediate (several years) and long (several decades) terms following the radionuclide release. As a result of the Chernobyl nuclear power plant accident in 1986, extensive forested areas in Europe were significantly contaminated with cesium, strontium, plutonium and other radionuclides. This study develops a dynamic model that describes the pathways of radionuclides which undergo complex transfer processes in forests and natural ecosystems. This generic model, FORESTRATH, calculates time-dependent radionuclide concentrations in forest compartments based on the information available on residence half-times. Because of the high complexity, traditional sampling programs often provide only limited and fragmented information for the ecosystem to be modeled. A model-directed sampling program was initiated which implies close feedback between ecosystem sampling and modeling of the radionuclide pathways using the FORESTPATH model. This program is now being applied by an international team of USA, European Union (EU) and Newly Independent States (NIS) members in the Chernobyl Nuclear Power Plant (NPP) Exclusion Zone.
