Book excerpt: In late 1971 we were involved in a study of the interaction of radiation with matter and were trying to use measurements of radiation fluorescence in biological molecules to indicate how radiation affected living cells. It soon became apparent that we were working in the dark; the doses we used to get a significant signal were too large to be of interest for radiation biology and although the DNA molecule appeared to be the most likely target molecule we did not know which sort of events and which sort oflesions were the most important. We decided to alter our approach to see if we could find any consistent mathematical order in the radiobiological dose relationships. We found that cell survival curves could be very usefully described by a linear-quadratic dose relationship and very soon came to the somewhat premature but, as it turned out, most effective conclusion that the induction of DNA double strand breaks should be linear-quadratic. In deciding that the DNA double strand break was the crucial and all-important lesion we were able to associate the mathematical analysis with the biology of the cell and were able to relate known properties of the DNA molecule to known radiobiological effects. On the other hand, we were restricted and brought, from an abstract two-hit lesion which could have any property one wished, down to earth, to a defined moleccular structure of nanometer dimensions and well-known functions and properties.

Available in PDF, EPUB and Kindle. Book excerpt: There can hardly be any doubt that radiation will continue to be an im portant factor in our lives. Present and future advances in atomic tech nology urgently require further work on research and development in the field of radiation biology if the maximum benefit is to be obtained at minimal risk from the various kinds of radiation that form a major by product of nuclear processes. Consequently, it is also necessary to prepare students and younger scientists for doing such work. The present book originates from teaching experience gained in lectures, seminars, and discussion groups started by the undersigned in 1957 and more recently held together with Drs. Dertinger and Jung. The friendly comments given to the German edition made us feel that it might be worth while to put the results of our efforts at the disposal of those to whom English is more familiar. In agreement with the view, based on well-known facts, that most if not aIl of the more striking practical achievements have resulted from patient and careful investigations into some basic problem, the book aims at introducing the reader to the methods of thought and experiment used in molecular radiation biology as weIl as to the results obtained thereby.

This book was released on 2012-12-06 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental understanding of the production of biological effects by ionizing radiation may well be one of the most important scientific objectives of mankind; such understanding could lead to the effective and safe utilization of the nuclear energy option. In addition, this knowledge will be of immense value in such diverse fields as radiation therapy and diagnosis and in the space program. To achieve the above stated objective, the U. S. Department of Energy (DOE) and its predecessors embarked upon a fundamental interdisciplinary research program some 35 years ago. A critical component of this program is the Radiological and Chemical Physics Program (RCPP). When the RCPP was established, there was very little basic knowledge in the fields of physics, chemistry, and biology that could be directly applied to understanding the effects of radiation on biological systems. Progress of the RCPP program in its first 15 years was documented in the proceedings of a conference held at Airlie, Virginia, in 1972. At this conference, it was clear that considerable progr:ess had been made in research on the physical and chemical processes in well-characterized systems that could be used to understand biological effects. During this period of time, most physical knowledge was obtained for the gas phase because the technology and instru mentation had not progressed to the point that measurements could be made in liquids more characteristic of biological materials.
Download or read book Understanding Radiation Biology written by Kenneth Chadwick and published by CRC Press. This book was released on 2019-11-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a qualitative and quantitative exploration of the action of radiation on living matter which leads to a complete and coherent interpretation of radiation biology. It takes readers from radiation-induced molecular damage in the nucleus of the cell and links this damage to cellular effects such as cell killing, chromosome aberrations and mutations before exploring organ damage, organism lethality and cancer induction. It also deals with radiological protection concepts and the difficulties of predicting the dose–effect relationship for low-dose and dose rate radiation risk. The book ends with separate chapters dealing with the effects of UV light exposure and risk classification of chemical mutagens, both of which are derived by logical extensions of the radiation model. This book will provide the basic foundations of radiation biology for undergraduate and graduate students in medical physics, biomedical engineering, radiological protection, medicine, radiology and radiography. Features Presents a comprehensive insight into radiation action on living matter Contains important implications for radiological protection and regulations Provides analytical methods for applications in radiotherapy

Available in PDF, EPUB and Kindle. Book excerpt: Physical Processes in Radiation Biology covers the proceedings of an International Symposium on Physical Processes in Radiation Biology, held at the Kellogg Center for Continuing Education, Michigan State University on May 6-8, 1963, sponsored by the U.S. Atomic Energy Commission. The symposium aims to address the core problems of radiation biology concerning the absorption, distribution, and utilization of high energy packets in biological systems. This book is composed of 21 chapters, and begins with an introduction to the absorption, excitation, and transfer processes in molecular solids. The subsequent chapters discuss the nature of exciton processes; the mechanisms of charge transport in biological materials; the interactions of fast and slow electrons with model systems; the importance of liquid structures in determining the development of radiation damage; and the nature of the metastable species formed. The concluding chapters explore the importance of charge migration in energy transfer processes in different biological systems and the significance of higher excited levels in charge migration and energy transfer. These chapters also describe the nature of the hydration of electrons and protons in aqueous systems. This book will be of great value to radiation biologists, biophysicists, physical chemists, and physicists.

Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned with features analysis of radiation damage to living matter at different levels of its organisation, beginning from the molecular level. The general theory of the mechanisms of biological action of radiation based on four logically connected principles of radiation biology is presented for the first time. The book contains abundant material on primary and secondary processes of the response of living systems to radiation, the mechanisms of direct and indirect action of radiation through radiolysis of water and lipids; a detailed consideration of the theory of targets (DNA and biological membranes) and the problems of high- and low-dose irradiation in the context of present-day. The systemic response of the cell to irradiation (oxidative stress, endogenous background radioresistance, damage and repair of biological membranes and DNA, systemic protection against radiation) is approximated. Presentation of these important problems is preceded by an up-to-date evaluation of some aspects regarding dosimetry of ionising radiation.
Download or read book Fundamentals Of Radiation Biology written by Susan B Klein and published by World Scientific. This book was released on 2023-01-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Radiation Biology presents a contemporary, comprehensive review of the interactions between ionizing radiations and biological materials, tracking the consequences to three inevitable endpoints: cell restitution, cell death, or cell transformation.The introductory narrative is followed by examination of larger scale phenomena including tissue responses to radiation injury, organ failure modes, and resultant human illness including cancer. Ultimately, Fundamentals of Radiation Biology considers circumstantial radiation incidents impacting biological systems including radiological terrorism and radiation pollution remediation. Chapters presenting an overview of carcinogenesis and radiation therapy techniques based in radiobiology discuss two significant expansions central to the concerns of the text.This book takes an unprecedented narrative approach to radiobiology; each chapter expands on the fundamentals surveyed previously to lead the reader steadily to a panorama of radiation biocomplexity. No biological event happens in isolation. Actions evoke reactions that alter structures and cause living systems to adapt. It also examines the components constituting mammalian radiation response machinery and correlates them with resultant physiological behaviors.

This book was released on 2013-11-11 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Office of Health and Environmental Research (OHER) has supported and continues to support development of computational approaches in biology and medicine. OHER's Radiological and Chemical Physics Program initiated development of computational approaches to determine the effects produced by radiation of different quality (such as high energy electrons, protons, helium and other heavy ions, etc. ) in a variety of materials of biological interest-such as water, polymers and DNA; these include molecular excitations and sub-excitations and the production of ionization and their spatial and temporal distribution. In the past several years, significant advances have been made in computational methods for this purpose. In particular, codes based on Monte Carlo techniques have ·been developed that provide a realistic description of track-structure produced by charged particles. In addition, the codes have become sufficiently sophisticated so that it is now possible to calculate the spatial and temporal distribution of energy deposition patterns in small volumes of subnanometer and nanometer dimensions. These dimensions or resolution levels are relevant for our understanding of mechanisms at the molecular level by which radiations affect biological systems. Since the Monte Carlo track structure codes for use in radiation chemistry and radiation biology are still in the developmental stage, a number of investigators have been exploring different strategies for improving these codes.
