Basic mechanisms in the radiation chemistry of aqueous media: proceedings of a conference [at] Gatlinburg, Tennessee, May[Alvin Glassner; Edwin James Hart; National Research Council (U.S.)]. “Principles of Radiation Interactions” Initial Physical Events The initial event is the transfer of ~ 7 - eV, an amount of energy sufficient to cause (multiple) ionizations or excitations in water molecules.

Transfer of energy to the medium in biological systems usually involves ionization of a water molecule, but can also involve the cellular macromolecules (e.g., DNA). According to the mechanism of radiation chemistry in an aqueous solution, 28 the reactions occur consecutively as follows: 1) Ionization of the water molecules 5.

From Conference on Basic Mechanisms in the Radiation Chemistry of Aqueous Media, Gatlinburg, Tenn., May Basic mechanisms involved in the radiation chemistry of proteins and nucleic acids are discussed.

Radiation chemistry of water and aqueous solutions has been intensively studied for many years, over the past century since the discovery of radiation. The book is ancient but it is very useful and interesting for students of doctoral studies of radiation chemistry (dosimetry, chemical evolutuion, polymer science, food irradiation, etc.).

This chapter provides an overview of the main principles that explain the chemical behavior of natural and unnatural environmental processes occurring in aqueous media. Chemical interactions in aqueous systems make up an important area of environmental chemistry, and the properties of water determine the behavior observed in solution.

ISBNThe trends in the basic research, R&D and industrial applications were scope of more applied uses of irradiation involving polymers ranged from discussions of the curing of materials for dental applications, to the effects on polyolefins (the most broadly used class of polymers prevalent in industrial radiation processing) and to.

Radiation chemistry is a subdivision of nuclear chemistry which is the study of the chemical effects of radiation on matter; this is very different from radiochemistry as no radioactivity needs to be present in the material which is being chemically changed by the radiation.

An example is the conversion of water into hydrogen gas and hydrogen peroxide. a branch of chemistry encompassing the chemical processes that arise from the effect of ionizing radiation on matter.

Both electromagnetic radiation, in the form of X rays, gamma rays, and radiant energy within the optical wavelengths, and fast charged particles, such as electrons, protons, alpha particles, and fragments of heavy nuclei, possess an ionizing capacity when.

Gamma radiation has been shown particularly useful for the functionalization of surfaces with stimuli-responsive polymers. This method involves the formation of active sites (free radicals) onto the polymeric backbone as a result of the high-energy radiation exposition over the polymeric material.

Thus, a microenvironment suitable for the reaction among monomer and/or Cited by: 9. Radiation Chemistry of Oxygenated Aqueous Solutions.

Peninsula of Giens, France, 25– The mechanisms by which radiation energy is deposited in matter depend upon the type of radiation. There are three types of ionizing radiation: (i) electro-magnetic radiation (X- and γ-rays), (ii) charged particles (electrons and heavy positive ions), and (iii) neutral particles (neutrons).

There are three important processes by which File Size: KB. Several comprehensive reviews of the radiation chemistry of aqueous solutions provide back- ground information on the field.(7- 10) It is apparent from the high-solute concentrations in the waste solutions that the fate of the primary products of water radiolysis is determined at very earlyCited by: 6.

Radiation chemistry of different classes of inorganic (water and aqueous solutions, inorganic solids, ionic liquids (ILs)) and organic substances (hydrocarbons, halogenated compounds, polymers, and biomolecules) is discussed in concise form together with theoretical and experimental backgrounds.

Proton transfer processes play an important role in many fields of chemistry. In dilute basic aqueous solutions, proton transfer from water molecules to hydroxide ions is aided by “presolvation”, i.e., thermal fluctuations that modify the hydrogen-bonding environment around the proton-receiving OH– ion to become more similar to that of a neutral H2O by: Comparison of General Chemistry Textbooks.

The complex chemistry that occurs in aqueous plasma systems is reactive in nature and is dependent on factors such as feed gas composition, aqueous solution composition, power input, and time parameters (e.g., plasma exposure time and lifetime of solution post-preparation).Ionizing radiation can induce some kinds of reactions, other than polymerization, such as dimerization, oligomerization, curing, and grafting.

These reactions occur through a regular radical chain causing growth of polymer by three steps, namely, initiation, propagation, and termination. To understand ionizing radiation-induced polymerization, the water radiolysis must be taken Cited by: 3.Description.
