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.

Book Synopsis Physical Processes in Radiation Biology by : Leroy Augenstein

Download or read book Physical Processes in Radiation Biology written by Leroy Augenstein. This book was released on 2013-10-22. 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.

Book Synopsis Advances in Radiation Biology by : John T. Lett

Download or read book Advances in Radiation Biology written by John T. Lett. This book was released on 2013-10-22. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Radiation Biology, Volume 9, provides an overview of the state of knowledge in radiation biology. The book contains nine chapters and begins with a study on the ways in which physical and chemical agents might trigger "regulatory dysfunction" and how these agents might interact with each other. This is followed by separate chapters on the mechanisms underlying changes in vascular function after doses of radiation in the therapeutic range and their role in the development of late effects in normal tissues; the future of hypoxic cell sensitizers in the clinical setting; DNA strand break formation by ionizing radiation; and major pathways which result in radiation-induced loss of cellular proliferative capacity. Subsequent chapters deal with the solid-state radiation chemistry of DNA; radiosensitivity of proliferating mammalian cells; the use of microwave/radiofrequency energy cancer treatment; and the decline of basic radiobiology.

Book Synopsis Molecular Radiation Biology by : Hermann Dertinger

Download or read book Molecular Radiation Biology written by Hermann Dertinger. This book was released on 2013-11-09. 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.
