Health Risks from Exposure to Low Levels of Ionizing Radiation


Book Description

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.




Cancer in Atomic Bomb Survivors


Book Description

Follow-up studies of persons exposed to medical radiation have long shown that radiation induces cancer in man. This, coupled with increasing exposure from other sources including occupational and environmental radiations, has resulted in greater recognition of the importance of research on radiation-induced carcinogenesis and risk assessment with a view to radiation protection. One of the well-known late effects of radiation is the increased incidence of leukemia that occurred among atomic bomb survivors beginning two or three years after expo sure. A remarkable increase of solid tumors including cancers of the thyroid, breast and lung was also observed 10 to 20 years after exposure. Thus, many pathological, clinical and epidemiological studies have been made on radiation carcinogenesis in atomic bomb survivors by investigators at the Atomic Bomb Casualty Commission (ABCC), now known as the Radiation Effects Research Foundation (RERF), as well as by the staff of universities in Hiroshima and Nagasaki. Some of the mechanisms involved in radia tion carcinogenesis in man and associated modifying factors, such as age at time of ex posure and sex, have been elucidated by these studies. The results obtained are being used by such agencies as the International Commission on Radiation Protection (ICRP) for risk estimations of radiation exposure. This monograph presents the results realized thus far in these epidemiological and The incidence of radiation-induced cancer among atomic bomb pathological studies.




The Children of Atomic Bomb Survivors


Book Description

Do persons exposed to radiation suffer genetic effects that threaten their yet-to-be-born children? Researchers are concluding that the genetic risks of radiation are less than previously thought. This finding is explored in this volume about the children of atomic bomb survivors in Hiroshima and Nagasakiâ€"the population that can provide the greatest insight into this critical issue. Assembled here for the first time are papers representing more than 40 years of research. These documents reveal key results related to radiation's effects on pregnancy termination, sex ratio, congenital defects, and early mortality of children. Edited by two of the principal architects of the studies, J. V. Neel and W. J. Schull, the volume also offers an important comparison with studies of the genetic effects of radiation on mice. The wealth of technical details will be immediately useful to geneticists and other specialists. Policymakers will be interested in the overall conclusions and discussion of future studies.




Adverse Reproductive Outcomes in Families of Atomic Veterans


Book Description

Over the past several decades, public concern over exposure to ionizing radiation has increased. This concern has manifested itself in different ways depending on the perception of risk to different individuals and different groups and the circumstances of their exposure. One such group are those U.S. servicemen (the "Atomic Veterans" who participated in the atmospheric testing of nuclear weapons at the Nevada Test Site or in the Pacific Proving Grounds, who served with occupation forces in or near Hiroshima and Nagasaki, or who were prisoners of war in or near those cities at the time of, or shortly after, the atomic bombings. This book addresses the feasibility of conducting an epidemiologic study to determine if there is an increased risk of adverse reproductive outcomes in the spouses, children, and grandchildren of the Atomic Veterans.




Health Effects of Exposure to Low Levels of Ionizing Radiation


Book Description

This book reevaluates the health risks of ionizing radiation in light of data that have become available since the 1980 report on this subject was published. The data include new, much more reliable dose estimates for the A-bomb survivors, the results of an additional 14 years of follow-up of the survivors for cancer mortality, recent results of follow-up studies of persons irradiated for medical purposes, and results of relevant experiments with laboratory animals and cultured cells. It analyzes the data in terms of risk estimates for specific organs in relation to dose and time after exposure, and compares radiation effects between Japanese and Western populations.




Analysis of Cancer Risks in Populations Near Nuclear Facilities


Book Description

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.







The Atomic Bombings of Hiroshima and Nagasaki


Book Description

The present book is originally a document of detailed expert investigation of the atomic bombing that took place at Hiroshima, Japan, during the final stage of the World War II by the United States. Army. Corps of Engineers. Manhattan District.




Cancer Registration


Book Description

Data obtained by population based cancer registries have a pivotal role in cancer control. Now also available in Spanish and French, this volume, which contains 15 authored chapters and four useful appendices, remains a standard reference for those planning to establish new cancer registries and those keen to adopt recognized methodologies. Information is given on the techniques required to collect, store, analyse and interpret data.




Nagasaki


Book Description

On August 9th, 1945, the US dropped an atomic bomb on Nagasaki. It killed a third of the population instantly, and the survivors, or hibakusha, would be affected by the life-altering medical conditions caused by the radiation for the rest of their lives. They were also marked with the stigma of their exposure to radiation, and fears of the consequences for their children. Nagasaki follows the previously unknown stories of five survivors and their families, from 1945 to the present day. It captures the full range of pain, fear, bravery and compassion unleashed by the destruction of a city.Susan Southard has interviewed the hibakusha over many years and her intimate portraits of their lives show the consequences of nuclear war. Nagasaki tells the neglected story of life after nuclear war and will help shape public debate over one of the most controversial wartime acts in history. Published for the 70th anniversary of the Hiroshima and Nagasaki bombs, this is the first study to be based on eye-witness accounts of Nagasaki in the style of John Hersey's Hiroshima. On August 9th, 1945, three days after the atomic bombing of Hiroshima, a 5-tonne plutonium bomb was dropped on the small, coastal city of Nagasaki. The explosion destroyed factories, shops and homes and killed 74,000 people while injuring another 75,000. The two atomic bombs marked the end of a global war but for the tens of thousands of survivors it was the beginning of a new life marked with the stigma of being hibakusha (atomic bomb-affected people). Susan Southard has spent a decade interviewing and researching the lives of the hibakusha, raw, emotive eye-witness accounts, which reconstruct the days, months and years after the bombing, the isolation of their hospitalisation and recovery, the difficulty of re-entering daily life and the enduring impact of life as the only people in history who have lived through a nuclear attack and its aftermath. Following five teenage survivors from 1945 to the present day Southard unveils the lives they have led, their injuries in the annihilation of the bomb, the dozens of radiation-related cancers and illnesses they have suffered, the humiliating and frightening choices about marriage they were forced into as a result of their fears of the genetic diseases that may be passed through their families for generations to come. The power of Nagasaki lies in the detail of the survivors' stories, as deaths continued for decades because of the radiation contamination, which caused various forms of cancer. Intimate and compassionate, while being grounded in historical research Nagasaki reveals the censorship that kept the suffering endured by the hibakusha hidden around the world. For years after the bombings news reports and scientific research were censored by U.S. occupation forces and the U.S. government led an efficient campaign to justify the necessity and morality of dropping the bombs. As we pass the seventieth anniversary of the only atomic bomb attacks in history Susan Southard captures the full range of pain, fear, bravery and compassion unleashed by the destruction of a city. The personal stories of those who survived beneath the mushroom clouds will transform the abstract perception of nuclear war into a visceral human experience. Nagasaki tells the neglected story of life after nuclear war and will help shape public discussion and debate over one of the most controversial wartime acts in history.
