Keywords: Molluscs; radioecology; Chernobyl; radioactive pollution

Abstract: Accumulation of radionuclides was studied in molluscs from the territories polluted by the Chernobyl outburst. In addition to radiochemical evaluation of ⁹⁰Sr, a simple method of beta-radiometry of shells was applied which allowed processing of extensive samples and mapping of contamination of large territories: the Dnieper drainage area and the Kiev administrative region. Pre-Hiroshima and pre-Chernobyl radioactivity was investigated in museum collections.

Abstract: Internal and external radiation exposures of aquatic organisms (algae, molluscs, fish) are estimated over the affected Chernobyl area. The estimates are made based on experimental data about radionuclide content in components of aquatic ecosystems of the Chernobyl Nuclear Power Plant (NPP) cooling pond, the Dnieper watershed rivers and the Dnieper reservoirs. To reconstruct and predict the radiation doses a mathematical model of an aquatic ecosystem was proposed, which was verified with monitoring data. The model describes dynamic processes of radionuclide migration and accumulation with allowance for ecological factors which are explicitly included in the model equations.

Anthropogenic influences on estuarine sedimentation and ecology: examples from the varved sediments of the Pettaquamscutt River Estuary, Rhode Island

Keywords: Pettaquamscutt River Estuary, Eutrophication, Land use change, Natural background conditions, Varve

Abstract: Estuaries and lakes are undergoing anthropogenic alterations as development and industry intensify in the modern world. Assessing the ecological health of such water bodies is difficult because accurate accounts of pre-anthropogenic estuarine/lacustrine conditions do not exist. Sediments preserved in water bodies provide archives of environmental changes that can be used to understand both natural and anthropogenic forcings. Here, a high-resolution, multi-proxy approach is used to reconstruct environmental conditions of the Pettaquamscutt River Estuary, Rhode Island, over the last millennium.

Abstract: Initial information since the releases of radioactive materials from the Fukushima Daiichi nuclear power plant, in Japan, shows that some animal food products are contaminated with 131I (mostly milk) and, to a lesser extent with 134Cs and 137Cs. Current knowledge on the transfer of these radioisotopes to animal products and available relevant countermeasures and management options to reduce radiation doses to humans are summarized. Much of this knowledge was obtained during the years of global fallout from atmospheric nuclear weapons tests and the response to the Chernobyl accident, in Ukraine in 1986.

Abstract: Data have been collected on concentrations of ¹³¹I in air, vegetation and milk from numerous locations receiving Chernobyl fallout. Time-integrated concentrations derived from these data are used to compare predictions from generic models used for routine environmental radiological assessments. In general, the models markedly overestimated the transfer of ¹³¹I over the air-grass-cow-milk pathway.

Keywords:

Abstract: The Chernobyl accident heavily contaminated the largest aquatic system in the Ukraine, requiring the development of a model-based decision support system in the field of aquatic radioecology. The main objectives of the system were to simulate and predict radionuclide dispersion in the Pripyat-Dnieper River-reservoir system, assess the effectiveness of special hydraulic countermeasures designed to decrease the rate of radionuclide dispersion in the water bodies, and support the Dnieper reservoirs’ management operations. A hierarchy of mathematical models was developed.

Abstract: The study of the area of Chernobyl nuclear power plant (NPP) using ERS SAR data was conducted under AO3-246 project and devoted to the monitoring of the forests state in the surrounding area. Our earlier analysis SIR-C/X SAR images of the area of interest showed, that X-band and C-band data are significantly worse for the forests classification purposes, than those from L-band.

Abstract: In summer 1990, four years after the Chernobyl accident, an IAEA coordinated survey was carried out in order to assess the radiological consequences and to study the possible effects of releases of (heavy) metals into the environment. Within the framework of this survey, lichens (Parmelia sulcata) were sampled in the Novozybkov, Bragin and Ovruc regions around Chernobyl and ¹³⁷Cs and Pb levels were determined by γ-ray spectroscopy and Graphite Furnace-Atomic Absorption Spectrometry (GF-AAS), respectively.
