Experts from academia and government who are actively engaged in research in the area of risk communication present a compendium of cases that give information and allow the development of strategies to improve the communication of scientific information to the public. The cases span Western, Central and Eastern Europe, covering such areas as nuclear waste, heavy metal contamination, landfill siting, risk perception, global warming, international health for all, and more. The conclusions and recommendations presented here are being used to develop future activities to further explore this area of risk communication as an international study. Audience: Scientists, risk communicators, psychologists, toxicologists, health professionals, and anyone who has an interest in public communication on scientific uncertainty.

Much has already been written about risk assessment. Epidemiologists write books on how risk assessment is used to explore the factors that influence the distribution of disease in populations of people. Toxicologists write books on how risk assess ment involves exposing animals to risk agents and concluding from the results what risks people might experience if similarly exposed. Engineers write books on how risk assessment is utilized to estimate the risks of constructing a new facility such as a nuclear power plant. Statisticians write books on how risk assessment may be used to analyze mortality or accident data to determine risks. There are already many books on risk assessment-the trouble is that they all seem to be about different sUbjects! This book takes another approach. It brings together all the methods for assessing risk into a common framework, thus demonstrating how the various methods relate to one another. This produces four important benefits: * First, it provides a comprehensive reference for risk assessment. This one source offers readers concise explanations of the many methods currently available for describing and quantifying diverse types of risks. * Second, it consistently evaluates and compares available risk assessment methods and identifies their specific strengths and limitations. Understand ing the limitations of risk assessment methods is important. The field is still in its infancy, and the problems with available methods are disappoint ingly numerous. At the same time, risk assessment is being used.

One of the greatest challenges facing those concerned with health and environmental risks is how to carry on a useful public dialogue on these subjects. In a democracy, it is the public that ultimately makes the key decisions on how these risks will be controlled. The stakes are too high for us not to do our very best. The importance of this subject is what led the Task Force on Environmental Cancer and Heart and Lung Disease to establish an Interagency Group on Public Education and Communication. This volume captures the essence of the "Workshop on the Role of Government in Health Risk Communication and Public Education" held in January 1987. It also includes some valuable appendixes with practical guides to risk communication. As such, it is an important building block in the effort to improve our collective ability to carry on this critical public dialogue. Lee M. Thomas Administrator, U. S. Environmental Protection Agency, and Chairman, The Task Force on Environmental Cancer and Heart and Lung Disease Preface The Task Force on Environmental Cancer and Heart and Lung Disease is an interagency group established by the Clean Air Act Amendments of 1977 (P.L. 95-95). Congress mandated the Task Force to recommend research to determine the relationship between environmental pollutants and human disease and to recommend research aimed at reduc ing the incidence of environment-related disease. The Task Force's Project Group on Public Education and Communication focuses on education as a means of reducing or preventing disease."

In recent years there has been substantial interest in benefits assessment methods, especially as these methods are used to assess health, safety, and environmental issues. At least part of this interest can be traced to Executive Order 12291, issued by President Ronald Reagan in 1981. This Executive Order requires Federal agencies to perform benefits assessments of pro posed major regulations and prohibits them from taking regulatory action unless potential benefits exceed potential costs to society. Heightened interest in benefits assessment methods has in tum given rise to greater recognition of the inherent difficulties in performing such assess ments. For example, many benefits that are intuitively felt to be most important are also among the most difficult to measure. It can be difficult to identify the full range of both benefits and costs. The choice of an appro priate discount rate for comparing benefits and costs over time is proble matic. Even when benefits are quantifiable in principle and agreement can be reached on their valuation, required d, ata may not be available. Thus considerable uncertainty is built into most benefit estimates, even when they are based on the best available data. In light of the complexities and difficulties associated with the perform ance of a benefits assessment, this book reviews the current state of theoretical and methodological knowledge in the field. The review is extensive in that it covers over fifty years of research, theoretical develop ment, and practice."

COMMUNICATING IN R!SK, CRISIS, AND HIGH STRESS SITUATIONS LEARN THE UNIFYING PRINCIPLES BEHIND RISK, CRISIS, AND HIGH STRESS COMMUNICATION WITH THIS STATE-OF-THE-ART REFERENCE WRITTEN BY A MAJOR LEADER IN THE FIELD Communicating in Risk, Crisis, and High Stress Situations: Evidence-Based Strategies and Practice is about communicating with people in the most challenging circumstances: high stress situations characterized by high risks and high stakes. The ability to communicate effectively in a high stress situation is an essential communication competency for managers, engineers, scientists, and professionals in every field who can be thrust into demanding situations complicated by stress. Whether you are confronting an external crisis, an internal emergency, or leading organizational change, this book was written for you. Communicating in Risk, Crisis, and High Stress Situations brings together in one resource proven scientific research with practical, hands-on guidance from a world leader in the field. The book covers such critical topics as trust, stakeholder engagement, misinformation, messaging, and audience perceptions in the context of stress. This book is uniquely readable, thorough, and useful, thanks to features that include: Evidence-based theories and concepts that underlie and guide practice Tools and guidelines for practical and effective planning and application Experience-based advice for facing challenges posed by mainstream and social media Provocative case studies that bring home the key principles and strategies Illuminating case diaries that use the author's breadth and depth of experience to create extraordinary learning opportunities The book is a necessity for managers, engineers, scientists, and others who must communicate difficult technical concepts to a concerned public. It also belongs on the bookshelves of leaders and communicators in public and private sector organizations looking for a one-stop reference and evidence-based practical guide for communicating effectively in emotionally charged situations. Written by a highly successful academic, consultant, and trainer, the book is also designed as a resource for training and education.

The subject of this volume--uncertainties in risk assessment and management--reflects an important theme in health, safety, and environ mental decision making. MOst technological hazards are characterized by substantial uncertainty. Recent examples include nuclear waste disposal, acid rain, asbestos in schools, carcinogens in food, and hazardous waste. realing with such uncertainty is arguably the most difficult and challeng ing task facing risk assessors and managers today. Four primary sources of uncertainty in risk assessment and management can be identified: (1) uncertainties about definitions; (2) uncertainties about scientific facts; (3) uncertainties about risk perceptions and atti tudes; and (4) uncertainties about values. Uncertainties about definitions derive primarily from disagreements about the meaning and interpretation of key concepts, such as probability. Uncertainties about scientific facts derive primarily from disagreements about failure modes, the probability and magnitude of adverse health or environmental consequences, cause and effect relationships, dose-response relationships, and exposure patterns. Uncertainties about risk perceptions and attitudes derive primarily from disagreements about what constitutes a significant or acceptable level of risk. Uncertainties about values derive primarily from disagreements about the desirability or worth of alternative risk management actions or conse quences. The papers in this volume address each of these sources of uncertainty from a variety of perspectives. Reflecting the broad scope of risk assess ment and risk management research, the papers include contributions from safety engineers, epidemiologists, toxicologists, chemists, biostatisticians, biologists, decision analysts, economists, psychologists, political scien tists, sociologists, ethicists, and lawyers.

The Social and Cultural Construction of Risk: Issues, Methods, and Case Studies Vincent T. Covello and Branden B. Johnson Risks to health, safety, and the environment abound in the world and people cope as best they can. But before action can be taken to control, reduce, or eliminate these risks, decisions must be made about which risks are important and which risks can safely be ignored. The challenge for decision makers is that consensus on these matters is often lacking. Risks believed by some individuals and groups to be tolerable or accept able - such as the risks of nuclear power or industrial pollutants - are intolerable and unacceptable to others. This book addresses this issue by exploring how particular technological risks come to be selected for societal attention and action. Each section of the volume examines, from a different perspective, how individuals, groups, communities, and societies decide what is risky, how risky it is, and what should be done. The writing of this book was inspired by another book: Risk and Culture: An Essay on the Selection of Technoloqical and Environmental Dangers. Published in 1982 and written by two distinguished scholars - Mary Douglas, a British social anthropologist, and Aaron Wildavsky, an American political scientist - the book received wide critical attention and offered several provocative ideas on the nature of risk selection, perception, and acceptance."

Public attention has focused in recent years on an array of technological risks to health, safety, and the environment. At the same time, responsibilities for technological risk as sessment, evaluation, and management have grown in both the public and private sectors because of a perceived need to anticipate, prevent, or reduce the risks inherent in modem society. In attempting to meet these responsibilities, legislative, judicial, regulatory, and private sector institutions have had to deal with the extraordinarily complex problems of assessing and balancing risks, costs, and benefits. The need to help society cope with technological risks has given rise to a new intellectual endeavor: the social and behavioral study of issues in risk evaluation and risk management. The scope and complexity of these analyses require a high degree of cooperative effort on the part of specialists from many fields. Analyzing social and behavioral issues requires the efforts of political scientists, sociologists, decision analysts, management scientists, econ omists, psychologists, philosophers, and policy analysts, among others."
