Biomaterials repair, reinforce or replace damaged functional parts of the (human) body. All mechanical and biological interactions between an implant and the body occur across the interface, which has to correspond as nearly as possible to its particular function. Much of the progress in adapting polymer materials for use in a biological environment has been obtained through irradiation techniques. For this reason the most recent developments in four key areas are reviewed in this special volume: (1) the analysis of the topology and the elemental composition of a functional surface, (2) the chemical modification of the surface which results in highly pure, sterile and versatile surfaces, (3) the sterilisation of implantable devices via ionising radiation and its possible effects on the structural mechanical properties of polymers, and (4) the radiation effects on living cells and tissues which are of particular importance for radiation protection and radiotherapy.

The Radiation Chemistry of Macromolecules is the first from a two-volume series aiming to contribute to the radiation chemistry in general. The chapters in this volume are divided into two major parts, where the first part deals with the basic processes and theory, while the second part tackles experimental techniques and applications to polyethylene. Part I focuses on the discussion on general principles of radiation effects; fundamental concepts on energy transfer; and the theory of free radicals. The subject of polymers is discussed thoroughly in several chapters including its molecular mobilities and electrical conductivity. Part II presents experimental techniques and a description of the radiation chemistry of a single polymer. This part also includes a discussion on the morphology of polyethylene and free radicals in irradiated polyethylene. This book is an important reference to students and scientists in the field of radiation chemistry of macromolecules.

The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.

Radiation-Processed Polysaccharides: Emerging Roles in Agriculture is the first book to focus exclusively on this emerging and important option for reducing the overuse and negative impact of agrochemicals in agriculture. Among practices being developed for effective and eco-friendly plant growth regulators in crop production, using radiation-processed polysaccharides (RPPs) is a promising technique. Comprised of chapters from diverse areas of plant science, including agriculture, agronomy, biotechnology, nanotechnology, molecular biology, and radiation agriculture, this book provides insights into the practical application of RPPs and inspires further research toward sustainable and efficient agricultural production. Polysaccharides (sodium alginate, carrageenan, chitosan and others) in their depolymerized state are increasingly important to agriculture based on their unique biological properties, biocompatibility, biodegradability and non-toxicity. Understanding the impact of RPPs on the plant phenotype, translocation of nutrients from source to sink, signal processing, and crosstalk helps improve the applicability of RPPs and sustainable agricultural yield. Presents the latest application of RPPs for improved plant production Includes insights for abiotic stress, biotechnology, nanotechnology and molecular application Explores the efficiency of natural polysaccharides as plant growth promoters

Written by practitioners experienced in the field, 'Practical Radiation Protection in Healthcare' provides a practical guide for medical physicists and others involved with radiation protection in the healthcare environment.

This book focuses on the conventional and emerging applications of radiations, which include radio waves and ultraviolet and gamma radiations. It discusses new techniques in radiation therapy and the effects of ionizing radiations on biological systems. The applications of radiations in the synthesis and use of nanoparticles along with the effects of hypergravity indicate a new trend. The book offers a concise account of the latest studies carried out so far and shows the new initiatives to be undertaken in the field of medicine and biology. It covers the medical use of radiations, such as ferrous sulfate–benzoic acid–xylenol orange dosimetry, Co-60 tomotherapy, radio-electro-chemotherapy, and fractional radiotherapy, and radiobiological effects, such as the effects of cell phone radiations on human health parameters and the combined effects of radiations and hypergravity on plants.

​This book provides an introduction of how radiation is processed in polymeric materials, how materials properties are affected and how the resulting materials are analyzed. It covers synthesis, characterization, or modification of important materials, e.g. polycarbonates, polyamides and polysaccharides, using radiation. For example, a complete chapter is dedicated to the characterization of biodegradable polymers irradiated with low and heavy ions. This book will be beneficial to all polymer scientists in the development of new macromolecules and to all engineers using these materials in applications. It summarizes the fundamental knowledge and latest innovations in research fields from medicine to space.

Radiation Effects in Materials, Volume 2: Radiation Chemistry of Organic Compounds provides information pertinent to the fundamental aspects of radiation chemistry of organic compounds. This book reviews the published work on the radiation chemistry of organic compounds. Organized into nine chapters, this volume begins with an overview of the study of the chemical reactions produced by high-energy radiation. This text then explores the two groups of radiation sources, namely, natural and artificial, that have been equally valuable for radiation chemistry. Other chapters consider the radiation chemistry of water and aqueous systems that is important to organic radiation chemistry. This book discusses as well how radiation alters simple organic compounds, and how the response varies with the irradiation conditions and the presence of other substances. The final chapter deals with the economic aspects of the use of radiation sources in industry. This book is a valuable resource for radiation chemists.
