Download or read book Radionuclide Contamination and Remediation Through Plants written by Dharmendra Kumar Gupta and published by Springer. This book was released on 2014-07-14 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the mechanistic (microscopic) understanding of radionuclide uptake by plants in contaminated soils and potential use of phytoremediation. The key features concern radionuclide toxicity in plants, how the radioactive materials are absorbed by plants, and how the plants cope with the toxic responses. The respective chapters examine soil classification, natural plant selection, speciation of actinides, kinetic modeling, and case studies on cesium uptake after radiation accidents. Radionuclide contaminants pose serious problems for biological systems, due to their chemical toxicity and radiological effects. The processes by which radionuclides can be incorporated into vegetation can either originate from activity interception by external plant surfaces (either directly from the atmosphere or from resuspended material), or through uptake of radionuclides via the root system. Subsequent transfer of toxic elements to the human food chain is a concrete danger. Therefore, the molecular mechanisms and genetic basis of transport into and within plants needs to be understood for two reasons: The effectiveness of radionuclide uptake into crop plants – so-called transfer coefficient – is a prerequisite for the calculation of dose due to the food path. On the other hand, efficient radionuclide transfer into plants can be made use of for decontamination of land – so-called phytoremediation, the direct use of living, green plants for in situ removal of pollutants from the environment or to reduce their concentrations to harmless levels.

Download or read book Radionuclides in the Environment written by Clemens Walther and published by Springer. This book was released on 2015-10-30 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides extensive and comprehensive information to researchers and academicians who are interested in radionuclide contamination, its sources and environmental impact. It is also useful for graduate and undergraduate students specializing in radioactive-waste disposal and its impact on natural as well as manmade environments. A number of sites are affected by large legacies of waste from the mining and processing of radioactive minerals. Over recent decades, several hundred radioactive isotopes (radioisotopes) of natural elements have been produced artificially, including 90Sr, 137Cs and 131I. Several other anthropogenic radioactive elements have also been produced in large quantities, for example technetium, neptunium, plutonium and americium, although plutonium does occur naturally in trace amounts in uranium ores. The deposition of radionuclides on vegetation and soil, as well as the uptake from polluted aquifers (root uptake or irrigation) are the initial point for their transfer into the terrestrial environment and into food chains. There are two principal deposition processes for the removal of pollutants from the atmosphere: dry deposition is the direct transfer through absorption of gases and particles by natural surfaces, such as vegetation, whereas showery or wet deposition is the transport of a substance from the atmosphere to the ground by snow, hail or rain. Once deposited on any vegetation, radionuclides are removed from plants by the airstre am and rain, either through percolation or by cuticular scratch. The increase in biomass during plant growth does not cause a loss of activity, but it does lead to a decrease in activity concentration due to effective dilution. There is also systemic transport (translocation) of radionuclides within the plant subsequent to foliar uptake, leading the transfer of chemical components to other parts of the plant that have not been contaminated directly.

Download or read book Radiation Dose Reconstruction for Epidemiologic Uses written by National Research Council and published by National Academies Press. This book was released on 1995-05-16 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing public concern about releases of radiation into the environment has focused attention on the measurement of exposure of people living near nuclear weapons production facilities or in areas affected by accidental releases of radiation. Radiation-Dose Reconstruction for Epidemiologic Uses responds to the need for criteria for dose reconstruction studies, particularly if the doses are to be useful in epidemiology. This book provides specific and practical recommendations for whether, when, and how studies should be conducted, with an emphasis on public participation. Based on the expertise of scientists involved in dozens of dose reconstruction projects, this volume: Provides an overview of the basic requirements and technical aspects of dose reconstruction. Presents lessons to be learned from dose reconstructions after Chernobyl, Three Mile Island, and elsewhere. Explores the potential benefits and limitations of biological markers. Discusses how to establish the "source term"â€"that is, to determine what was released. Explores methods for identifying the environmental pathways by which radiation reaches the body. Offers details on three major categories of dose assessment.

Download or read book Soil-Plant Transfer of Radionuclides in Non-Temperate Environments written by International Atomic Energy Agency and published by . This book was released on 2021-11-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication considers radionuclide transfer in tropical and arid environments with a focus on root uptake by crops from soils. The data collected and analysed are relevant for estimating the transfer of radionuclides through food chains to humans and for assessing radiation doses to the public due to intakes of these radionuclides in plant products used as food. The data relate to equilibrium conditions between the radionuclide's dynamics into and out of the compartments of the environment and are appropriate for radiological environmental impact assessment in planned and existing exposure situations where such conditions have been established. Moreover, this publication classifies the data according to an international climate classification scheme and compares the summary values derived for tropical and arid environments with those presented in IAEA Technical Reports Series No. 472 for temperate environments.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, radioactive contamination in the environment by uranium (U) and its daughters has caused increasing concerns globally. This book provides recent developments and comprehensive knowledge to the researchers and academicians who are working on uranium contaminated areas worldwide. This book covers topics ranging from the beginning of the nuclear age until today, including historical views and epidemiological studies. Modelling practices and evaluation of radiological and chemical impact of uranium on man and the environment are included. Also covered are analytical methods used for the determination of uranium in geo/bio environments. Some chapters explore factors which influence uranium speciation and in consequence plant uptake/translocation. Last but not least, several chapters provide approaches and practices for remediation of uranium contaminated areas.

Download or read book Nuclear and Radiological Emergencies in Animal Production Systems, Preparedness, Response and Recovery written by Ivancho Naletoski and published by Springer Nature. This book was released on 2021-05-31 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access volume explains how major nuclear and radiological emergencies (NREs) can have implications at local, national and international level. The response to NREs requires a competent decision-making structure, clear communication and effective information exchange. National veterinary services have the responsibility to plan, design and manage animal production system in their countries. These activities cover animal health, animal movement control, production control and improvement, and control of the products of animal origin before their placement on the market. Release of radionuclides after NREs can cause substantial contamination in the animal production systems. Critical responsibility of veterinary authorities is therefore to prevent such contamination, establish early response mechanisms to mitigate the consequences and prevent placement of contaminated products of animal origin on the market for human consumption. This work summarizes the critical technical points for effective management of NREs for national veterinary services.
