To chart a strategy for shifting to alternatives to cesium chloride, the James Martin Center for Nonproliferation Studies (CNS), with the support of the Foreign and Commonwealth Office of the United Kingdom, held a workshop in January 2014 among relevant stakeholders from domestic and foreign governments, industry, health providers, security experts, and the nongovernmental community. The workshop helped generate recommendations in this domain and in the broader area of replacements for radiological sources. Following the workshop discussions, the CNS team conducted a substantive review of the state of scholarly and policy best practices to date, consulting with relevant experts - this report details the subsequent insights and recommendations

In the United States there are several thousand devices containing high-activity radiation sources licensed for use in areas ranging from medical uses such as cancer therapy to safety uses such as testing of structures and industrial equipment. Those radiation sources are licensed by the U.S. Nuclear Regulatory Commission and state agencies. Concerns have been raised about the safety and security of the radiation sources, particularly amid fears that they could be used to create dirty bombs, or radiological dispersal device (RDD). In response to a request from Congress, the U.S. Nuclear Regulatory Commission asked the National Research Council to conduct a study to review the uses of high-risk radiation sources and the feasibility of replacing them with lower risk alternatives. The study concludes that the U.S. government should consider factors such as potential economic consequences of misuse of the radiation sources into its assessments of risk. Although the committee found that replacements of most sources are possible, it is not economically feasible in some cases. The committee recommends that the U.S. government take steps to in the near term to replace radioactive cesium chloride radiation sources, a potential "dirty bomb" ingredient used in some medical and research equipment, with lower-risk alternatives. The committee further recommends that longer term efforts be undertaken to replace other sources. The book presents a number of options for making those replacements.

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.

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.

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.

This volume aims to improve understanding of nuclear security and the prevention of nuclear terrorism. Nuclear terrorism is perceived as one of the most immediate and extreme threats to global security today. While the international community has made important progress in securing fissile material, there are still important steps to be made with nearly 2,000 metric tons of weapons-usable nuclear material spread around the globe. The volume addresses this complex phenomenon through an interdisciplinary approach: legal, criminal, technical, diplomatic, cultural, economic, and political. Despite this cross-disciplinary approach, however, the chapters are all linked by the overarching aim of enhancing knowledge of nuclear security and the prevention of nuclear terrorism. The volume aims to do this by investigating the different types of nuclear terrorism, and subsequently discussing the potential means to prevent these malicious acts. In addition, there is a discussion of the nuclear security regime, in general, and an important examination of both its strengths and weaknesses. In summary, the book aims to extend the societal and political debate about the threat of nuclear terrorism. This book will be of much interest to students of nuclear proliferation, nuclear governance, terrorism studies, international organizations, and security studies in general.

This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

The papers included in this volume comprise research from participants in the 2018 Nuclear Scholars Initiative and the Project on Nuclear Issues (PONI) Conference Series. PONI sponsors this research to provide a forum for facilitating new and innovative thinking and to provide a platform for emerging thought leaders across the nuclear enterprise. The papers in this volume span a wide range of technical and policy issues, further discussion in their respective areas, and provide innovative recommendations for pressing challenges. To that end, these papers explore such topics as the impacts of emerging technologies and capabilities, deep-diving on nuclear strategy and national policies, proposing paths forward for addressing proliferation challenges, and enhancing arms control in contentious environments.
