Available in PDF, EPUB and Kindle. Book excerpt: Balance studies of environmental iodine 131 over a period of 30 days are reported in children ranging from 1 to 6 years of age. Calculations of expected thyroidal accumulations of iodine 131, based on accepted exponential models and thyroidal function factors, are compared with thyroidal iodine 131 measurements performed in a low-background facility. The measured values were lower by a factor of 2 than the calculated accumulation of iodine 131, suggesting a lesser uptake and/or more rapid turnover of iodine in children. The difficulties involved in this type of environmental study and recommendations for improved methodology are discussed.

Download or read book Exposure of the American People to Iodine 131 from Nevada Nuclear Bomb Tests written by National Research Council and published by National Academies Press. This book was released on 1999-05-17 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, after more than a decade of research, the National Cancer Institute (NCI) released a report which provided their assessment of radiation exposures that Americans may have received from radioactive iodine released from the atomic bomb tests conducted in Nevada during the 1950s and early 1960s. This book provides an evaluation of the soundness of the methodology used by the NCI study to estimate: Past radiation doses. Possible health consequences of exposure to iodine-131. Implications for clinical practice. Possible public health strategiesâ€"such as systematic screening for thyroid cancerâ€"to respond to the exposures. In addition, the book provides an evaluation of the NCI estimates of the number of thyroid cancers that might result from the nuclear testing program and provides guidance on approaches the U.S. government might use to communicate with the public about Iodine-131 exposures and health risks.
Download or read book Review of the Hanford Thyroid Disease Study Draft Final Report written by National Academy of Sciences and published by National Academies Press. This book was released on 2000-03-01 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1986, officials of the US Department of Energy revealed that the Hanford Atomic Products Operations in Richland, Washington, had been releasing radioactive material, in particular iodine-131, into the environment over a period of years. This information, which confirmed the suspicions of some people in the Pacific Northwest about what they called the Hanford Reservation or just Hanford, created quite a stir. Both the US Congress and citizens of the Northwest became keenly interested in knowing whether these radiation releases had caused human health effects. They were particularly concerned about whether Hanford releases of iodine-131 had led to an increase in thyroid disease among the population of the area. In 1988, Congress ordered a study of the human health effects of exposure to the iodine-131 released from Hanford. Funded by the Centers for Disease Control and Prevention (CDC), the study was carried out by the Seattle-based Fred Hutchinson Cancer Research Center over the last decade. The study examined estimate of exposure of the thyroid and rates of thyroid disease because iodine-131 concentrates in the thyroid and that organ would be the best indicator of radiation damage in the population. The Centers for Disease Control and Prevention (CDC) asked the National Academy of Sciences-National Research Council (NAS-NRC) to give an independent appraisal of the study methodology, results, and interpretation and of the communication of the study results to the public. Review of the Hanford Thyroid Disease Study Draft Final Report constitutes the response of the NRC subcommittee to that request. To respond to the charge, the NRC subcommittee felt that it needed to go beyond the specific questions addressed to it by CDC and develop a broad understanding and critique of the HTDS and the Draft Final Report. As part of those activities, the subcommittee solicited comments from outside experts and members of the public primarily in a public meeting held in Spokane, Washington, in June 1999, where 14 scientists and members of the public made formal presentations to the subcommittee about various aspects of the Draft Final Report. Other members of the public also spoke during four open-comment sessions at the meeting. In addition, efforts were made to evaluate all information materials prepared for the public and additional CDC communication plans. Information was gathered through interviews with journalists, members of concerned citizen groups in the Hanford region, members of the CDC scientific and media staff in Atlanta, and the HTDS investigators. In this summary, the main points follow the structure of our report and are presented under several headings: epidemiologic and clinical methods and data collection, dosimetry, statistical analyses, statistical power and interpretation of the study, and communication of the study results to the public. We then provide a brief synopsis of our response to the questions raised by CDC.

Book excerpt: These guidelines are an update of the 1999 World Health Organization (WHO) guidance on the use of iodine thyroid blocking (ITB) with a special focus on public health considerations of ITB implementation.These guidelines provide a recommendation on iodine thyroid blocking (ITB), via oral administration of stable iodine, as an urgent protective action in responding to a nuclear accident. This recommendation aims to support emergency planners, policy makers, public health specialists, clinicians and other relevant stakeholders, in order to strengthen public health preparedness for radiation emergencies in WHO Member States as required by the International Health Regulations (IHR) and in line with the international safety standards (GSR Part 7). The scope of the guidelines is confined to public health aspects of planning and implementation of ITB before and during a radiation emergency, such as dosage and timing of ITB administration, adverse effects of stable iodine, its packaging, storage, and distribution.
Download or read book Iodine and Inorganic Iodides written by J. Risher and published by World Health Organization. This book was released on 2009 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iodine is a naturally occurring element and inorganic iodines found in the ocean accumulate in fish, shellfish and seaweed. Industrially iodine is used in many applications including the manufacture of inks, dyes, photographic agents and in water-purification. In the health-care industry, iodine is widely used as a disinfectant/biocide and in the production of soaps, bandages, and medicines. Iodine is also included as a salt in some countries to provide dietary supplementation. This Concise International Chemical Assessment Document (CICAD) evaluates the scientific literature on the health aspects of iodine and inorganic iodides. Its focus is on the health effects from environmental exposures beyond those associated with the diet and nutritional supplementation. Radioactive iodine isotopes are regarded as outside the scope of the document.
Download or read book Distribution and Administration of Potassium Iodide in the Event of a Nuclear Incident written by National Research Council and published by National Academies Press. This book was released on 2003-12-17 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radioactive iodines are produced during the operation of nuclear power plants and during the detonation of nuclear weapons. In the event of a radiation incident, radioiodine is one of the contaminants that could be released into the environment. Exposure to radioiodine can lead to radiation injury to the thyroid, including thyroid cancer. Radiation to the thyroid from radioiodine can be limited by taking a nonradioactive iodine (stable iodine) such as potassium iodide. This book assesses strategies for the distribution and administration of potassium iodide (KI) in the event of a nuclear incident. The report says that potassium iodide pills should be available to everyone age 40 or youngerâ€"especially children and pregnant and lactating womenâ€"living near a nuclear power plant. States and municipalities should decide how to stockpile, distribute, and administer potassium iodide tablets, and federal agencies should keep a backup supply of tablets and be prepared to distribute them to affected areas.
Download or read book Reducing Environmental Cancer Risk written by Suzanne H. Reuben and published by DIANE Publishing. This book was released on 2010-10 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.
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.

This book was released on 2002-07-19 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
Download or read book The Arctic Aeromedical Laboratory s Thyroid Function Study written by National Research Council and published by National Academies Press. This book was released on 1996-01-26 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1950s, with the Cold War looming, military planners sought to know more about how to keep fighting forces fit and capable in the harsh Alaskan environment. In 1956 and 1957, the U.S. Air Force's former Arctic Aeromedical Laboratory conducted a study of the role of the thyroid in human acclimatization to cold. To measure thyroid function under various conditions, the researchers administered a radioactive medical trace, Iodine-131, to Alaska Natives and white military personnel; based on the study results, the researchers determined that the thyroid did not play a significant role in human acclimatization to cold. When this study of thyroid function was revisited at a 1993 conference on the Cold War legacy in the Arctic, serious questions were raised about the appropriateness of the activityâ€"whether it posed risks to the people involved and whether the research had been conducted within the bounds of accepted guidelines for research using human participants. In particular, there was concern over the relatively large proportion of Alaska Natives used as subjects and whether they understood the nature of the study. This book evaluates the research in detail, looking at both the possible health effects of Iodine-131 administration in humans and the ethics of human subjects research. This book presents conclusions and recommendations and is a significant addition to the nation's current reevaluation of human radiation experiments conducted during the Cold War.
