It is not always the case that the subject of a scientific book and its relevance to everyday li fe are so timely. Photobiology and its si ster subject Radiobiology are now a must for understanding the environment we live in and the impact light, ultraviolet light, and radiation have on all aspects of our life. Photobiology is a true interdisciplinary field. Photobiology research plays a direct role in diverse fields, and a glance at the topics of the symposia covered in this book by over 100 articles shows the breadth and depth of knowledge acquired in fundamental research and its impact on the major issues and applied problems the world is facing. Half a century of photobiology research brought about an understanding of the importance of light to life, both as a necessary source of energy and growth as weIl as its possible dangers. Research in photochemistry and photobiology led to the discoveries of ceIlular repair mechanisms of UV induced damages to DNA and this led to understanding of the effects of hazardous environmental chemieals and mutagenecity , and to the development of genetic engineering. This topic was given due emphasis in several symposia and chapters in this book.

Radiation Measurement in Photobiology deals with the measurement of optical radiation and its application in photobiology. Optical radiation detectors as well as the calibration of light sources and detectors are discussed, together with techniques for spectroradiometry and broadband radiometry. Action spectroscopy and ultraviolet radiation dosimetry are also considered. Comprised of nine chapters, this volume begins with an introduction to the basic principles of light measurement, followed by a survey of optical radiation detectors based on physical principles and the problems associated with calibration. The next three chapters deal with important applications and extensions of these radiant measurements, including a short review of biological and medical users of lasers. The final three chapters on specialized studies and developments illustrate the wide diversity that exists in photobiology. These cover ultraviolet radiation dosimetry using polymer films, computer modeling of terrestrial ultraviolet radiation, and the "diffusion optics" in biological media. This book should be of interest to photobiologists.

Molecular Photobiology: Inactivation and Recovery describes the deleterious photochemical reactions occurring in biological systems. This book is composed of 10 chapters that specifically tackle light interactions in the ultraviolet region of the spectrum resulting to damaged proteins and nucleic acids in living systems. This book deals first with the kinds of photochemical reactions that can occur and the possible effects of photochemistry on molecular, cellular, and organismal levels. The succeeding chapters highlight the principle of recovery mechanisms, wherein evidence shows that cells can repair their damaged genetic material, and thus recover from the otherwise inactivating effects of light. The remaining chapters are devoted to the comparison and contrast of some biological effects of ionizing radiation and those of ultraviolet radiation. This book is of value to molecular photobiologists, photochemists, biochemists, and radiation scientists and researchers.

The goals of the science of photobiology can be divided into four cate gories: to develop (1) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and phys icists, because photobiology is a truly multidisciplinary science. While a multidisciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for the oretical or practical use. Photochemical and Photobiological Reviews continues to provide in-depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger sci entists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate.

Photochemistry and Photobiology of Nucleic Acids: Volume II, Biology is a collection of papers that deals with the biological effects due to stable UV induced alterations in critical cellular macromolecules, including cell death, growth delay, mutagenesis, and carcinogenesis. The papers assume that DNA is the macromolecule most relevant to cell pathology, as well as to the photochemical and photobiological properties of RNA which are essential in cellular functions. One paper investigates the UV-induced cross-linkings of proteins with nucleic acids as a possible cause of biological effects other than just in terms of the damage done to nucleic acids. Other papers discuss the mechanisms of protection against, and in the repair of damage caused by UV photons and by ionizing radiation (also chemical mutagens) in many organisms from viruses to mammalian cells. The repair processes appear to play a role in monitoring and preserving the structural integrity of DNA during physiological processes such as replication and transcription. One paper notes that in experiments on human embryonic lung fibroblasts WI-38 at very high radiation doses, radiation products of Thy in acid-soluble form appear while products from the DNA (acid-precipitable fraction) disappear. The paper suggests that the excision process is therefore selective. The collection is suitable for biochemists, microbiologists, or academicians whose works involve genetics, cancer, and cellular research.

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.

A comprehensive review of non-ionizing radiation and its public health and environmental risks, for researchers, policy makers, and laymen This book explains the characteristics of all forms of electromagnetic non-ionizing radiation (NIR) and analyzes the relationship between exposure and its biological effects, as well as the known dose-response relationships associated with each. Taking a uniquely holistic approach to the concept of health that builds upon the WHO definition to include not only absence of disease, but the physical, mental and social well-being of individuals and the population, it reviews established and potential risks and protections, along with regulatory issues associated with each. The risks to public health of NIR, whether in the form of UV light, radio waves from wireless devices, or electric and magnetic fields associated with electrical power systems, is currently a cause of great concern among members of the public and lawmakers. But in order to separate established science from speculation and make informed decisions about how to mitigate the risks of NIR and allocate precious resources, policymakers, manufacturers, and individuals need a comprehensive source of up-to-date information based on the current scientific evidence. Written by a team of experts in their fields, this book is that source. Among other things, it: Summarizes scientific findings on the safety of different forms of NIR and the rationale behind current standards Describes devices for monitoring NIR along with the established and potential hazards of each form Explores proper protections against UV light and lasers, RF radiation, ELF fields and other forms of NIR Discusses how to avoid injuries through occupational training or public awareness programs, and how to perform medical assessments in cases of suspected NIR injuries Considers how to decide whether or not to spend money on certain mitigation measures, based on cost-benefit analyses Offering expert reviews and analyses of the latest scientific findings and public policy issues concerning the risks to public health and the environment of NIR, Non-ionizing Radiation Protection is an indispensable source of information for manufacturers, government regulators, and regulatory agencies, as well as researchers, concerned laypersons, and students.

Radiotherapy of Intraocular and Orbital Tumors presents a new approach to the role of radiation therapy in the management of ophthalmic cancer. The indications for ultrasonography, computed tomography, and magnetic resonance imaging studies are analyzed, and treatment techniques, together with their results, are described for each tumor. Particle beam and plaque irradiation are reviewed, and conservative and surgical management of radiation effects are detailed. In the past, most books on this subject included a chapter on radiotherapy but emphasized the dangers of radiation complications. However, great progress in understanding the effects of irradiation upon the tissues of the eye and orbit, new therapeutic equipment, and new imaging techniques (CT, MRI) allow for careful treatment planning. This book has taken the long overdue step of reconsidering the role of irradiation of the eye so that it may take its place as a respected, rather than feared, treatment in the combined modality approach so important today. Together with experts in relevant fields, the editors have produced a refreshingly clear and thoroughly referenced volume which will be a valuable asset to all ophthalmologists, radiation oncologists, pediatricians, endocrinologists, oncologists, and residents in training, as well as to students in these disciplines.

The US Environmental Protection Agency Office of Radiation and Indoor Air asked the National Research Council to evaluate whether sufficient new data exist to warrant a reassessment of health risks reported in Health Effects of Exposure to Low Levels of Ionizing Radiations (BEIR V) in 1990. To respond to this request, the National Research Council assembled the Committee on Health Risks of Exposure to Low Levels of Ionizing Radiations. The work of the committee was conducted in what was called the BEIR VII phase-1 study. To assist the committee during its deliberations, various scientists were consulted for advice, and a workshop on the impact of biology on risk assessment was held in collaboration with the Department of Energy Office of Health and Environmental Research. The intent of the workshop was to address the implications of new understanding of the biologic basis of radiation injury and carcinogenesis for risk assessment.
