This book was released on 2020-01-13 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing knowledge about the mechanisms of carcinogenesis and the critical analysis of the assumption on which the no-threshold linear relation is based have advanced, but dose-effect relations must be found which optimize the overall epidemiological and experimental data. It is abundantly clear that the standards that will be enforced upon the entry into the force of the International directive no longer enjoy the scientific justifications which made them credible, and that concepts like collective dose and the ALARA (As Low As reasonably Achievable) principle are obsolete. Yet this merely raises, with even greater sharpness, the key question: what can replace them? In this respect, research on the influence of variations in natural irradiation on cancer frequently represent a vital source of information. Radiological protection has entered what some call a turbulence zone, others a renewal. The dogmas on which it lived for more than two decades have been questioned, giving the medical and scientific community a dual responsibility.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation and published by National Academies Press. This book was released on 2006-03-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Radiation and the Immune System Current Knowledge and Future Perspectives written by Katalin Lumniczky and published by Frontiers Media SA. This book was released on 2018-05-03 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: For long, high dose ionizing radiation was considered as a net immune suppressing agent, as shown, among others, by the exquisite radiosensitivity of the lymphoid system to radiation-induced cell killing. However, recent advances in radiobiology and immunology have made this picture more complex. For example, the recognition that radiation-induced bystander effects, share common mediators with various immunological signalling processes, suggests that they are at least partly immune mediated. Another milestone was the finding, in the field of onco-immunology, that local tumor irradiation can modulate the immunogenicity of tumor cells and the anti-tumor immune responsiveness both locally, in the tumor microenvironment, and at systemic level. These observations paved the way for studies exploring optimal combinations of radiotherapy and immunotherapy in order to achieve a synergistic effect to eradicate tumors. However, not all interactions between radiation and the immune system are beneficial, as it was recognized that many of radiation-induced late side effects are also of immune and inflammatory nature. Currently perhaps the most studied field of research in radiation biology is focused around the biological effects of low doses, where many of the observed pathophysiological endpoints are due to mechanisms other than direct radiation-induced cell killing and are immune-related. Finally, it must not be forgotten that the interactions between the ionizing radiations and the immune system are bi-directional, and activation of the immune system also influences the outcome of radiation exposure. This Research Topic brings together 23 articles and aims to give an overview of the complex and very often contradictory nature of the interactions between ionizing radiation and the immune system. Due to its increasing penetrance in the population both through medical diagnostic or environmental sources or during cosmic travel low dose ionizing radiation exposure is becoming a major epidemiological concern world-wide. Several of the articles within the Research Topic specifically address potential long-term health consequences and the underlying mechanisms of low dose radiation exposure. A major intention of the Editors was also to draw the attention of the non-radiobiological scientific community on the fact that ionizing radiation is by far more than purely an immune suppressing agent.
Download or read book Radiation in Medicine written by Committee for Review and Evaluation of the Medical Use Program of the Nuclear Regulatory Commission and published by National Academies Press. This book was released on 1996-04-08 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does radiation medicine need more regulation or simply better-coordinated regulation? This book addresses this and other questions of critical importance to public health and safety. The issues involved are high on the nation's agenda: the impact of radiation on public safety, the balance between federal and state authority, and the cost-benefit ratio of regulation. Although incidents of misadministration are rare, a case in Pennsylvania resulting in the death of a patient and the inadvertent exposure of others to a high dose of radiation drew attention to issues concerning the regulation of ionizing radiation in medicine and the need to examine current regulatory practices. Written at the request from the Nuclear Regulatory Commission (NRC), Radiation in Medicine reviews the regulation of ionizing radiation in medicine, focusing on the NRC's Medical Use Program, which governs the use of reactor-generated byproduct materials. The committee recommends immediate action on enforcement and provides longer term proposals for reform of the regulatory system. The volume covers Sources of radiation and their use in medicine. Levels of risk to patients, workers, and the public. Current roles of the Nuclear Regulatory Commission, other federal agencies, and states. Criticisms from the regulated community. The committee explores alternative regulatory structures for radiation medicine and explains the rationale for the option it recommends in this volume. Based on extensive research, input from the regulated community, and the collaborative efforts of experts from a range of disciplines, Radiation in Medicine will be an important resource for federal and state policymakers and regulators, health professionals involved in radiation treatment, developers and producers of radiation equipment, insurance providers, and concerned laypersons.

Download or read book Behavior of Radionuclides in the Environment II written by Alexei Konoplev and published by Springer Nature. This book was released on 2020-05-19 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is Volume II in a three-volume set on the Behavior of Radionuclides in the Environment, focusing on Chernobyl. Now, so many years after the Chernobyl accident, new data is emerging and important new findings are being made. The book reviews major research achievements concerning the behavior of Chernobyl-derived radionuclides, including their air transport and resuspension, mobility and bioavailability in the soil-water environment, vertical and lateral migration in soils and sediments, soil-to-plant and soil-to-animal transfer, and water-to-aqueous biota transfer. The long-term dynamics of radionuclides in aquatic ecosystems are also discussed, in particular, the heavily contaminated cooling pond of the Chernobyl Nuclear Power Plant, which is in the process of being decommissioned. Lessons learned from long-term research on the environmental behavior of radionuclides can help us understand the pathways of environmental contamination, which, in turn, will allow us to improve methods for modeling and predicting the long-term effects of pollution. This book features a wealth of original data and findings, many of which have never been published before, or were not available internationally. The contributing authors are experts from Ukraine, Russia and Belarus with more than 30 years of experience investigating Chernobyl-derived radionuclides in the environment. The content presented here can help to predict the evolution of environmental contamination following a nuclear accident, and specifically the Fukushima Dai-ichi nuclear power plant accident.

Download or read book Radiation Hormesis and the Linear No Threshold Assumption written by Charles L. Sanders and published by Springer Science & Business Media. This book was released on 2009-11-07 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by National Research Council and published by National Academies Press. This book was released on 2006-04-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: BEIR VII develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation. It is among the first reports of its kind to include detailed estimates for cancer incidence in addition to cancer mortality. In general, BEIR VII supports previously reported risk estimates for cancer and leukemia, but the availability of new and more extensive data have strengthened confidence in these estimates. A comprehensive review of available biological and biophysical data supports a "linear-no-threshold" (LNT) risk modelâ€"that the risk of cancer proceeds in a linear fashion at lower doses without a threshold and that the smallest dose has the potential to cause a small increase in risk to humans. The report is from the Board on Radiation Research Effects that is now part of the newly formed Nuclear and Radiation Studies Board.
