Radiation Biophysics

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.

This newly revised and updated edition of Radiation Biophysics provides an in-depth description of the physics and chemistry of radiation and its effects on biological systems. Coverage begins with fundamental concepts of the physics of radiation and radioactivity, then progresses through the chemistry and biology of the interaction of radiation with living systems. The Second Edition of this highly praised text includes major revisions which reflect the rapid advances in the field. New material covers recent developments in the fields of carcinogenesis, DNA repair, molecular genetics, and the molecular biology of oncogenes and tumor suppressor genes. The book also includes extensive discussion of the practical impact of radiation on everyday life. Covers the fundamentals of radiation physics in a manner that is understandable to students and professionals with a limited physics background Includes problem sets and exercises to aid both teachers and students Discusses radioactivity, internally deposited radionuclides, and dosimetry Analyzes the risks for occupational and non-occupational workers exposed to radiation sources

What is biophysics? As with all subjects which straddle traditional boundaries between fields, it eludes a precise definition. Furthermore, it is impossible to do biophysics without having a certain foundation of knowledge in biology, physics, physical chemistry, chemistry and biochemistry. One approach to a biophysics textbook would be to refer the student to the literature of these neighboring fields, and to leave the selection of the appropriate supplementary material up to the student. The editors of this volume are of the opinion that it is more useful and less time-consuming to present a selection of the supplementary knowledge, in concentrated form, together with the subject matter specific to biophysics. The reader will thus find in this book introductions to such subjects as the structure and function of the cell, the chemical structure of biogenic macromolecules, and even theoretical chemistry. What, indeed, is biophysics? Must we consider it to include physiology, electromedicine, radiation medicine, etc. ? The field has evolved continuously in recent years. Molecular understanding oflife processes has come more and more to the fore. Just as the field of molecular physics has developed to describe structures and processes in the realm of non-living systems, there has been a corresponding development of molecular biophysics.

Biophysics Is An Interdisciplinary Subject-A ``Bridge`` Between Physical And Natural Sciences. Recent Advances In Physical Sciences, And Progress That Are Taking Place In Biological And Medical Sciences, Are Making Them More Data-Rich, And Has Brought The Subject Of Biophysics To The Center Stage. The Subject Of This Book Is Thus Conceived And Presented Taking Into Account These Developments To Reach Out To The Students And Scholars With Biological And Medical Background, To Make Them Knowledgeable About The Physical Principles And Techniques That Are Becoming An Integral Part Of Their Subjects, And To Inculcate The Quantitative Approach In Natural Sciences, Which Is The Essential Part Of Physical Sciences. This Book Is Also Aimed At The Physical Sciences Faculties, To Bring To Their Awareness, The Structural And Functional Aspects Of Biological Entities And The Complexity, And The Emerging Trends In Natural Sciences. In Essence, This Book Is To Reach Out To The Students Of Physical Sciences Also, Whose Convergent Interest Is In The Biological/Medical Sciences.The Book Contains All The `Core` Topics In Biophysics, Presented In A Lucid Manner, Emphasizing The Quantitative Approach Towards Biological, Medical And Allied Subjects. Overviews To Sections, And Synopses To Chapters, Are Provided To Present The Subject Matter And Concepts In A Condensed Format. Appendices, Glossary And Index Are Included To Make The Book Self-Contained, And To Facilitate The Reader A Quick Perusal Of Technical Concepts And Terms.

Biophysics represents perhaps one of the best examples of interdisciplinary research areas, where concepts and methods from disciplines such as physics, biology, b- chemistry, colloid chemistry, and physiology are integrated. It is by no means a new ?eld of study and has actually been around, initially as quantitative physiology and partly as colloid science, for over a hundred years. For a long time, biophysics has been taught and practiced as a research discipline mostly in medical schools and life sciences departments, and excellent biophysics textbooks have been published that are targeted at a biologically literate audience. With a few exceptions, it is only relatively recently that biophysics has started to be recognized as a physical science and integrated into physics departments’ curr- ula, sometimes under the new name of biological physics. In this period of cryst- lization and possible rede?nition of biophysics, there still exists some uncertainty as to what biophysics might actually represent. A particular tendency among phy- cists is to associate biophysics research with the development of powerful new te- niques that should eventually be used not by physicists to study physical processes in living matter, but by biologists in their biological investigations. There is value in that judgment, and excellent books have been published that introduce the int- ested reader to the use of physical principles for the development of new methods of investigation in life sciences.
