Radiobiology and Radiation Hormesis by Charles L. Sanders Pdf

This book presents new information on radiobiology that more clearly refutes the linear no-threshold (LNT) assumption and supports radiation hormesis. Fresh light is cast on the mechanisms of radiation hormesis and the potential benefits of low-dose ionizing radiation in preventing and treating a wide variety of inflammatory and proliferative diseases. It is proposed that these effects may derive from cellular communication via electromagnetic waves directed by DNA, with each cell acting as a quantum computer. Readers will also find close analysis of the negative impacts of radiophobia on many aspects of modern life, including attitudes to imaging technologies, licensing of nuclear power reactors, and preparedness for survival of nuclear war. The book will be of interest to researchers and scientists in radiobiology, radiation protection, health physics, medical physics, and radiology. Specifically, it will provide medical physicians, radiation oncologists, radiation epidemiologists, gerontologists, cell biologists, toxicologists, and nuclear engineers with a wide range of interesting facts and enlightening novel perspectives.

Radiation Hormesis by T. D. Luckey Pdf

Radiation Hormesis presents the only critical review of the effects of whole-body exposure to low doses of ionizing radiation in animals. This is a "must read" book for radiobiologists, health-conscious individuals, and serious environmentalists. Topics discussed include our radiation environment, radiation hormesis in cancer mortality, growth and development, reproduction and mutation, immunity, and cancer. Data is presented that indicates that low doses of ionizing radiation may actually be beneficial to human health. This information could invalidate the "zero thesis" and linear models used by most regulatory agencies. The implications regarding eliminating linear models and accepting radiation hormesis are also discussed.

Radiation Hormesis and the Linear-No-Threshold Assumption by Charles L. Sanders Pdf

Current radiation protection standards are based upon the application of the linear no-threshold (LNT) assumption, which considers that even very low doses of ionizing radiation can cause cancer. The radiation hormesis hypothesis, by contrast, proposes that low-dose ionizing radiation is beneficial. In this book, the author examines all facets of radiation hormesis in detail, including the history of the concept and mechanisms, and presents comprehensive, up-to-date reviews for major cancer types. It is explained how low-dose radiation can in fact decrease all-cause and all-cancer mortality and help to control metastatic cancer. Attention is also drawn to biases in epidemiological research when using the LNT assumption. The author shows how proponents of the LNT assumption consistently reject, manipulate, and deliberately ignore an overwhelming abundance of published data and falsely claim that no reliable data are available at doses of less than 100 mSv.

Radiation Biophysics (ionizing Radiations) by I︠U︡riĭ Borisovich Kudri︠a︡shov Pdf

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.

Health Risks from Exposure to Low Levels of Ionizing Radiation by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation,National Research Council Pdf

This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.

Genetic Instability and Some Unusual Radiobiological Effects by Ekaterina S. Evstratova Pdf

Genetic instability leads to the accumulation of many changes necessary to transform the stable genome of a normal cell into an unstable genome. Such a transformation can be the cause of radiation mutagenesis, carcinogenesis and aging - the main long-term effects of ionizing radiation, UV light, and other harmful environmental factors. A new quantitative assessment of the genetic instability was suggested, taking into account the delay in the formation of colonies by cells surviving after exposure to harmful agents. It was demonstrated that the genetic instability of yeast cells is mainly determined by cell ploidy, but not by the sigmoid shape of the survival curve or the cell's ability of post-irradiation recovery. New experimental data confirm the participation of recovery processes in the manifestation of the relative biological effectiveness of densely ionizing radiation both for cell inactivation and for radiation-induced genetic instability. A number of universal patterns of synergic interactions are demonstrated, which did not depend on the used biological test and objects nor the interacting physical and chemical factors. Potential significance of synergy at low intensities of physical and chemical environmental factors is proved. Original data on the influence of cyclic heating and cooling on cell survival are obtained. It is concluded that osmotic homeostasis of cells, along with DNA, is an important target responsible for cell viability under the damaging action of various agents. Data on the favorable effect of the increased natural background of ionizing radiation are discussed. The manifestations of radiation hormesis were revealed for various radiation accidents, professional and medical exposure. The results obtained demonstrate that the action of high-energy ionizing radiation is accompanied by irradiation with UV light that occurs when charged particles move at a speed exceeding the speed of light in a given medium.

Fundamentals of Radiation and Chemical Safety by Ilya Obodovskiy Pdf

Fundamentals of Radiation and Chemical Safety covers the effects and mechanisms involved in radiation and chemical exposure on humans. The mechanisms and effects of these damaging factors have many aspects in common, as do their research methodology and the methods used for data processing. In many cases of these types of exposures the same final effect can also be noted: Cancer. Low doses of radiation and small doses of chemical exposure are continuously active and they could influence the entire population. The analysis of these two main source hazards on the lives of the human population is covered here for the first time in a single volume determining and demonstrating their common basis. Fundamentals of Radiation and Chemical Safety includes the necessary knowledge from nuclear physics, chemistry and biology, as well the methods of processing the experimental results. This title focuses on the effects of low radiation dosage and chemical hormesis as well as the hazards associated with, and safety precautions in radiation and chemicals, rather than the more commonly noted safety issues high level emergencies and disasters of this type. Brings together, for the first time, the problems of radiation and chemical safety on a common biophysical basis. Relates hazards caused by ionizing radiation and chemicals and discusses the common effective mechanisms Outlines common methodology and data processing between radiation and regular chemical hazards Concerns primarily with low levels of radiation and chemical exposure

The Future of Low Dose Radiation Research in the United States by National Academies of Sciences, Engineering, and Medicine,Division on Earth and Life Studies,Nuclear and Radiation Studies Board Pdf

Exposures at low doses of radiation, generally taken to mean doses below 100 millisieverts, are of primary interest for setting standards for protecting individuals against the adverse effects of ionizing radiation. However, there are considerable uncertainties associated with current best estimates of risks and gaps in knowledge on critical scientific issues that relate to low dose radiation. The Nuclear and Radiation Studies Board of the National Academies hosted the symposium on The Future of Low Dose Radiation Research in the United States on May 8 and 9, 2019. The goal of the symposium was to provide an open forum for a national discussion on the need for a long-term strategy to guide a low dose radiation research program in the United States. The symposium featured presentations on low dose radiation programs around the world, panel discussions with representatives from governmental and nongovernmental organizations about the need for a low dose radiation research program, reviews of low dose radiation research in epidemiology and radiation biology including new directions, and lessons to be learned from setting up large research programs in non-radiation research fields. This publication summarizes the presentation and discussion of the symposium.

Radiobiology for the Radiologist by Eric J. Hall,Amato J. Giaccia Pdf

In print since 1972, this seventh edition of Radiobiology for the Radiologist is the most extensively revised to date. It consists of two sections, one for those studying or practicing diagnostic radiolo, nuclear medicine and radiation oncology; the other for those engaged in the study or clinical practice of radiation oncology--a new chapter, on radiologic terrorism, is specifically for those in the radiation sciences who would manage exposed individuals in the event of a terrorist event. The 17 chapters in Section I represent a general introduction to radiation biology and a complete, self-contained course especially for residents in diagnostic radiology and nuclear medicine that follows the Syllabus in Radiation Biology of the RSNA. The 11 chapters in Section II address more in-depth topics in radiation oncology, such as cancer biology, retreatment after radiotherapy, chemotherapeutic agents and hyperthermia. Now in full color, this lavishly illustrated new edition is replete with tables and figures that underscore essential concepts. Each chapter concludes with a "summary of pertinent conclusions" to facilitate quick review and help readers retain important information.
