      Biological pathways and chemical behavior of plutonium and other actinides in the environment / Roger C. Dahlman, Ernest A. Bondietti, and L. Dean Eyman; Application of the box model theory to the geophysical transport of PuO₂: geochemistry of Pu(NO₃)₄ / A.T. Jakubick. The actinide elements (atomic numbers 89 through ) involve the filling of 5f orbitals. All actinides are radioactive, but only uranium and the lighter actinides have half-lives long enough to be present in Earth's environment. The heavier actinides are produced by nuclear reactions and some have very.

    Actinides | Actinides are an important, if sometimes unwanted, part of highly technological societies. Actinides pose an extreme scientific challenge to the materials research community. Their complex electronic structure results in many abnormal properties that even today are not well understood. Most of the motivation for EM to dispose of the higher actinides is the perception that they are a hazard to people or the environment. 6 However, the scientific basis for determining the biological and environmental effects of the higher actinides and consequently their risks and disposal requirements is limited (see, for example, Sontag,

    Actinoid element, also called actinide element, any of a series of 15 consecutive chemical elements in the periodic table from actinium to lawrencium (atomic numbers 89–). As a group, they are significant largely because of their gh several members of the group, including uranium (the most familiar), occur naturally, most are man-made.   @article{osti_, title = {Final Technical Progress Report Long term risk from actinides in the environment: Modes of mobility}, author = {Kirchner, Thomas B}, abstractNote = {The key source of uncertainty in assessing actinide mobility is the relative importance of transport by: (1) wind erosion, (2) water erosion, and (3) vertical migration.

Actinides in the environment refer to the sources, environmental behaviour and effects of actinides in Earth's environment. Environmental radioactivity is not limited solely to actinides; non-actinides such as radon and radium are of note.

ISBN: OCLC Number: Notes: "Published in cooperation with NATO Scientific Affairs Division." "Proceedings of the NATO Advanced Study Institute on Actinides and the Environment, Maleme, Crete, Greece, July"--Title page verso. The handling of actinides and actinide-based materials provides significant technological challenges due to the toxicity and radioactivity associated with these materials.

These challenges are particularly apparent in the nuclear power industry. Under normal operation, a reactor can produce a. ―Lanthanide and Actinide Chemistry, Simon Cotton, Uppingham School, Uppingham, Rutland, UK.

Lanthanide and Actinide Chemistry is a one-volume account of the Lanthanides (including scandium and yttrium), the Actinides and the Transactinide elements, intended as an introductory treatment for undergraduate and postgraduate by: This volume is a continuation of the five volumes of "The Chemistry of the Actinide and Transactinide Elements" (published ).

It expounds on topics in actinide science that are undergoing rapid scientific developments and that are germane to the safe development of nuclear energy in the 21 st century, from nuclear fuels to the environmental science and management of : Hardcover.

Hundreds of chemically active compounds and minerals reside within the earth’s formations, and every patch of rock and soil is composed of its own particular mix. The waters that flow upon and. The actinides successively fill the 5f sublevel.

Many actinide metals have properties of both d block and f block elements. Actinides display several valence states, typically more than the lanthanides.

Most are prone to hybridization. The actinides (An) may be prepared by reduction of AnF3 or AnF4 with vapors of Li, Mg, Ca, or Ba at C. The influence of the following parameters is discussed: oxidation state (Eh), hydrolysis (pH), solubility, complex formation, colloid formation, sorption and filtration effects.

The oxidation states of the actinides in neutral aqueous media are plotted as a function of the redox potential. Hydrolysis, stability of 1∶1 carbonato complexes, of humic acid complexes and solubilities of the Cited by: Radioactivity in the Environment.

The third group, chaptersfocuses on specialized topics that encompass contemporary fields related to actinides in the environment, in the human body, and in storage or wastes.

Two appendices at the end of volume 5 tabulate important nuclear properties of all actinide and transactinide isotopes. Introduction. The aquatic chemistry of actinides is a very broad research field having received much attention over the last decades.

Many different aspects have been studied reflecting wide relevance ranging from fundamental studies into basic chemical properties, to actinide coordination chemistry, complex formation with inorganic and organic ligands, structural investigations of Cited by: 5.

The actinide or actinoid elements are a series of elements including atomic number 89 (actinium) through (lawrencium). Here is a list of elements that are actinides, a subset of the rare earth elements group. Discussions of actinide elements may refer to any member of the group by the symbol An.

All of the elements are f-block elements.

Division of Nuclear Chemistry and Technology.; American Chemical Society. Meeting;]. All actinide isotopes are radioactive. Since the middle of the last century, new bactinide and transactinide isotopes have been artificially produced and the use of several of the naturally occurring actinide isotopes has increased.

This production is due to the nuclear power industry and the military fabrication and use of nuclear weapons. These activities have created anxiety about the Author: Degueldre, Claude. The fourth edition of "The Chemistry of the Actinide and Transactinide Elements" comprises all chapters in volumes 1 through 5 of the third edition (published in ) plus a new volume 6.

To remain consistent with the plan of the first edition, “ to provide a comprehensive and uniform treatment of the chemistry of the actinide [and transactinide] elements for both the nuclear Reviews: 1. Actinides occur between Groups 3 and 4 in Period 7 of the periodic table.

All elements in this family are radioactive (that is, they spontaneously release subatomic particles or energy as their nuclei decay). Five actinides have been found in nature: thorium, protoactinium, uranium, neptunium, and plutonium.

Much is understood about sorption of actinides on surfaces, the mode of migration of actinides in such waters and the potential effects of these radioactive species on marine biota, but much more understanding of the behavior of the actinides in the environment is needed to allow proper and reliable modeling needed for disposition of nuclear Cited by:   @article{osti_, title = {Long-Term Risk From Actinides In The Environment: Modes Of Mobility}, author = {Breshears, David D}, abstractNote = {The mobility of actinides in surface soils remains a key issue of concern at several DOE facilities in arid and semiarid environments, including Rocky Flats, Hanford, Nevada, Idaho, and Los Alamos.
