Comparative Dosimetry of Radon in Mines and Homes

Comparative Dosimetry of Radon in Mines and Homes PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309044847
Category : Medical
Languages : en
Pages : 257

Book Description
Studies of underground miners have provided a wealth of data about the risk of lung cancer from exposure to radon's progeny elements, but the application of the miner data to the home environment is not straightforward. In Comparative Dosimetry of Radon in Mines and Homes, an expert committee uses a new dosimetric model to extrapolate to the home environment the risk relationships found in the miner studies. Important new scaling factors are developed for applying risk estimates based on miner data to men, women, and children in domestic environments. The book includes discussions of radon dosimetry and the uncertainties concerning other risk factors such as age and smoking habits. The book also contains a thorough technical discussion of the characteristics of radioactive aerosols in domestic environments, the dose of inhaled radon progeny to different age groups, identification of respiratory tract cells at the greatest risk of carcinogenesis, and a complete description of the new lung dose model being developed by the International Commission on Radiological Protection as modified by this committee.

Health Risks of Radon and Other Internally Deposited Alpha-Emitters

Health Risks of Radon and Other Internally Deposited Alpha-Emitters PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309037891
Category : Science
Languages : en
Pages : 623

Book Description
This book describes hazards from radon progeny and other alpha-emitters that humans may inhale or ingest from their environment. In their analysis, the authors summarize in one document clinical and epidemiological evidence, the results of animal studies, research on alpha-particle damage at the cellular level, metabolic pathways for internal alpha-emitters, dosimetry and microdosimetry of radionuclides deposited in specific tissues, and the chemical toxicity of some low-specific-activity alpha-emitters. Techniques for estimating the risks to humans posed by radon and other internally deposited alpha-emitters are offered, along with a discussion of formulas, models, methods, and the level of uncertainty inherent in the risk estimates.

Radiation Dose Reconstruction for Epidemiologic Uses

Radiation Dose Reconstruction for Epidemiologic Uses PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309176832
Category : Science
Languages : en
Pages : 150

Book Description
Growing public concern about releases of radiation into the environment has focused attention on the measurement of exposure of people living near nuclear weapons production facilities or in areas affected by accidental releases of radiation. Radiation-Dose Reconstruction for Epidemiologic Uses responds to the need for criteria for dose reconstruction studies, particularly if the doses are to be useful in epidemiology. This book provides specific and practical recommendations for whether, when, and how studies should be conducted, with an emphasis on public participation. Based on the expertise of scientists involved in dozens of dose reconstruction projects, this volume: Provides an overview of the basic requirements and technical aspects of dose reconstruction. Presents lessons to be learned from dose reconstructions after Chernobyl, Three Mile Island, and elsewhere. Explores the potential benefits and limitations of biological markers. Discusses how to establish the "source term"â€"that is, to determine what was released. Explores methods for identifying the environmental pathways by which radiation reaches the body. Offers details on three major categories of dose assessment.

Biologic Markers in Pulmonary Toxicology

Biologic Markers in Pulmonary Toxicology PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 9780309039901
Category : Science
Languages : en
Pages : 204

Book Description
Biologic markersâ€"indicators of biological exposure or changeâ€"offer the promise of early detection of disease caused by environmental exposure. Researchers have used these markers to discover indications of pulmonary damage from low-level ozone, a finding with serious implications for health professionals and environmental regulators. Biologic Markers in Pulmonary Toxicology is a comprehensive study of this use of biologic markers. Focusing on the respiratory tract as an entryway for airborne pollutants, this volume reviews new ways of measuring markers, the need for markers to indicate dose or exposure levels, noninvasive respiratory function tests for use with healthy humans to detect sensitivity to inhaled pollutants, approaches to evaluating markers down to the cellular and biochemical levels, and more.

How Tobacco Smoke Causes Disease

How Tobacco Smoke Causes Disease PDF Author: United States. Public Health Service. Office of the Surgeon General
Publisher:
ISBN:
Category : Government publications
Languages : en
Pages : 728

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Environmental Tobacco Smoke

Environmental Tobacco Smoke PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309074568
Category : Medical
Languages : en
Pages : 351

Book Description
This comprehensive book examines the recent research investigating the characteristics and composition of different types of environmental tobacco smoke (ETS) and discusses possible health effects of ETS. The volume presents an overview of methods used to determine exposures to environmental smoke and reviews both chronic and acute health effects. Many recommendations are made for areas of further research, including the differences between smokers and nonsmokers in absorbing, metabolizing, and excreting the components of ETS, and the possible effects of ETS exposure during childhood and fetal life.

Air Pollution, the Automobile, and Public Health PDF Author: Sponsored by The Health Effects Institute
Publisher: National Academies Press
ISBN: 0309037263
Category : Science
Languages : en
Pages : 703

Book Description
"The combination of scientific and institutional integrity represented by this book is unusual. It should be a model for future endeavors to help quantify environmental risk as a basis for good decisionmaking." â€"William D. Ruckelshaus, from the foreword. This volume, prepared under the auspices of the Health Effects Institute, an independent research organization created and funded jointly by the Environmental Protection Agency and the automobile industry, brings together experts on atmospheric exposure and on the biological effects of toxic substances to examine what is knownâ€"and not knownâ€"about the human health risks of automotive emissions.
