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 The Future of Low Dose Radiation Research in the United States written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. 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.

Download or read book Science and Decisions written by National Research Council and published by National Academies Press. This book was released on 2009-03-24 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.
Download or read book Assessment of the Scientific Information for the Radiation Exposure Screening and Education Program written by National Research Council and published by National Academies Press. This book was released on 2005-10-01 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Radiation Exposure Compensation Act (RECA) was set up by Congress in 1990 to compensate people who have been diagnosed with specified cancers and chronic diseases that could have resulted from exposure to nuclear-weapons tests at various U.S. test sites. Eligible claimants include civilian onsite participants, downwinders who lived in areas currently designated by RECA, and uranium workers and ore transporters who meet specified residence or exposure criteria. The Health Resources and Services Administration (HRSA), which oversees the screening, education, and referral services program for RECA populations, asked the National Academies to review its program and assess whether new scientific information could be used to improve its program and determine if additional populations or geographic areas should be covered under RECA. The report recommends Congress should establish a new science-based process using a method called "probability of causation/assigned share" (PC/AS) to determine eligibility for compensation. Because fallout may have been higher for people outside RECA-designated areas, the new PC/AS process should apply to all residents of the continental US, Alaska, Hawaii, and overseas US territories who have been diagnosed with specific RECA-compensable diseases and who may have been exposed, even in utero, to radiation from U.S. nuclear-weapons testing fallout. However, because the risks of radiation-induced disease are generally low at the exposure levels of concern in RECA populations, in most cases it is unlikely that exposure to radioactive fallout was a substantial contributing cause of cancer.
Download or read book Analysis of Cancer Risks in Populations Near Nuclear Facilities written by National Research Council and published by National Academies Press. This book was released on 2012-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1980s, the National Cancer Institute initiated an investigation of cancer risks in populations near 52 commercial nuclear power plants and 10 Department of Energy nuclear facilities (including research and nuclear weapons production facilities and one reprocessing plant) in the United States. The results of the NCI investigation were used a primary resource for communicating with the public about the cancer risks near the nuclear facilities. However, this study is now over 20 years old. The U.S. Nuclear Regulatory Commission requested that the National Academy of Sciences provide an updated assessment of cancer risks in populations near USNRC-licensed nuclear facilities that utilize or process uranium for the production of electricity. Analysis of Cancer Risks in Populations near Nuclear Facilities: Phase 1 focuses on identifying scientifically sound approaches for carrying out an assessment of cancer risks associated with living near a nuclear facility, judgments about the strengths and weaknesses of various statistical power, ability to assess potential confounding factors, possible biases, and required effort. The results from this Phase 1 study will be used to inform the design of cancer risk assessment, which will be carried out in Phase 2. This report is beneficial for the general public, communities near nuclear facilities, stakeholders, healthcare providers, policy makers, state and local officials, community leaders, and the media.

This book was released on 2012 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forlagets beskrivelse: NCRP Report No. 171, Uncertainties in the Estimation of Radiation Risks and Probability of Disease Causation, considers the types and magnitude of the several uncertainties that are a component of the risk assessment process for cancer, heritable and noncancer effects following radiation exposure. These uncertainties can result from the nature of the input data as well as from the specific analysis and models used for developing the risk estimates. Topics addressed in this Report include: (a) uncertainties associated with extrapolation of dose-response relationships observed in primary epidemiological studies to estimate the risk per unit dose (i.e., organ dose or whole-body dose) in the U.S. population and other exposed populations; (b) applications of meta-analyses or pooled analyses to increase the statistical power in evaluating uncertainties in dose-response relationships for exposed human populations; (c) uncertainties associated with extrapolation of dose-response relationships observed for populations exposed to acute doses of high-energy gamma rays to estimate the risk per unit dose in populations exposed to fractionated or low-dose rate chronic exposures; (d) uncertainties associated with extrapolation of the dose-response relationships observed for populations exposed to high-energy gamma rays to estimate the risk per unit dose in populations exposed to low-energy photons, low-energy electrons, alpha particles, and neutrons with various energies; (e) comparison of uncertainties associated with risk estimated for individual tissue or organ sites with the uncertainties associated with estimating risk of all tumors combined due to whole-body exposure; (f) evaluation of opportunities for using additional epidemiological and laboratory-based biological information to modify estimates of uncertainty in risk estimation for cancer, noncancer effects, and severe heritable disorders; (f) procedures for accounting for dose uncertainty in epidemiological dose-response analyses; and (g) evaluation of the combined effect of uncertainty in dose estimation with the uncertainty in estimation of risk per unit dose in estimating the overall risk. This Report also provides a comprehensive analysis of uncertainties on the estimation of probability of radiation-induced disease, including: (1) application of organ doses and associated uncertainties in estimation of probability of disease causation; (2) evaluation of inherent uncertainties in calculating the probability of disease causation (in an individual), or assigned share of excess relative risk for various types of cancer attributable to radiation exposure; and (3) methods of improving existing procedures for estimating disease probability based on input organ doses and their uncertainties. The issue of uncertainty in estimation of radiation-induced risks of cancer, noncancer diseases, and heritable genetic effects analyzed in this Report is of great importance in evaluating the effects of ionizing radiation on human health, in decisions involving the safe use of ionizing radiation and in addressing public controversy. Uncertainty analyses should become increasingly important in the future as the sophisticated methodologies continue to develop and become more available.

This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Accurate exposure estimation in radiation epidemiologic studies is essential for reliable health risk assessment. Failure to account appropriately for uncertainties in dose estimation and model assumptions could lead to biased results in the evaluation of the radiation dose-response as well as incorrect confidence bounds for risk parameters. Assessment of absorbed dose is often subject to considerable uncertainties, and a variety of statistical approaches have been developed to incorporate dose uncertainties into the estimation and inference for the dose-response. The purpose of this Commentary is to provide a guide regarding available statistical methods for dose-response analysis that incorporate dose uncertain-ties, the types of studies to which the methods can be applied, and the advantages and disadvantages of the methods. This Commentary addresses studies of external and internal exposures and provides guidance on both shared and unshared uncertainty in the estimation of absorbed dose. Of particular interest are statistical methods for assessing dose-response in epidemiologic studies of internal emitters, for which doses are calculated using exposure and retention models with many parameters. Each parameter is associated with various sources and amounts of uncertainty"--

This book was released on 2012-10-28 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.
