Radon was discovered in 1900 but it was not until the 1950's that an awareness of its potential as a hazard to humans developed. This resulted primarily from a recognition of the high levels of exposure for uranium miners. Measurement of high concentrations of radon in homes led environmental health agencies to focus on radon as a health hazard and has resulted in concern from scientists, the medical profession and the general public. It is in this context that the author undertook the writing of this book. A need for a broader understanding of radon in the general environment in addition to that of indoors has become apparent. Since much of the author's research has to do with outdoor radon and its decay products, it seems appropriate to have a book available stressing studies on outdoor radon as well was that found indoors. This book is intended to fill a gap in our knowledge of radon concentration in the outdoor atmosphere as well as to provide results of previously published indoor measurements. In addition, work on radon decay product ion concentrations in these environments contributes a unique set of results on effects of radon and its decay products on the electrical characteristics of the atmosphere. These studies are important both from their significant contribution to human dose as well as their role in the atmospheric electrical environment.

Radon is a natural radioactive gas used to estimate the radioactive hazard in the environment. Radon (222Rn), which is one of the daughters of uranium (238U), represents the most essential isotope, with a half-life of 3.825 days. The associated health risks due to inhalation and ingestion of radon and its progeny when present in enhanced levels in an indoor environment like a human dwelling have been documented. In this chapter, we have discussed the sources and techniques besides the methods used for measuring radon gas in the environment including soil, water, building materials, et cetera, which are well documented. A wide range of techniques for the detection and quantification of radon has been developed over the last few years. There is no single technique that can meet all the requirements of the different types of the radon measurements. Finally, we have mentioned the most essential information effecting the radon monitoring in the environment and the methods of measuring and controlling the concentration values throughout the environment; we have also mentioned the effect of radon on the inhabitants through the estimation of the effective dose rates and lung cancer risk due to radon gas when its values exceed the action level values.

The Natural Radiation Environment Symposium (NRE VII), the Seventh in the NRE series, which commenced forty years ago in 1963 at Rice University Texas, was held in Rhodes (Greece) in May 2002. During the intervening four decades the research work presented at these NRE Symposia has contributed to a deeper understanding of natural radiation and in particular of its contribution to human radiation exposures. It is clear from the quality and diversity of the 143 papers in this volume of Radioactivity in the Environment series that the study of the natural radiation environment is an active and continually expanding field of research. The papers in this volume fall into a number of main and topical research areas namely: the measurement and behaviour of natural radionuclides in the environment cosmic radiation measurement and dosimetry the external penetrating radiation field at ground level TENR (Technologically Enhanced Natural Radiation) and NORM (Naturally Occurring Radioactive Materials) studies assessment of the health effects of radon regulatory aspects of natural radiation exposures In these papers the results of many new surveys of natural radionuclide levels in the environment and of improved methods of detection are described. While some of the natural radiation sources investigated are unmodified by human activity, many accounts are given here of exposures to natural sources which have been enhanced by technology. Such TENR and NORM exposures are shown to range from activities such as mining, oil and gas exploitation, the use of industrial by-products as building materials, to space travel to name but a few. In several cases quite high doses to some individuals are shown to occur. Accounts are given here of methods to prevent and reduce exposures to such sources.

In the book Radon, some segments of modern research from a wide range of issues related to radioactive gas radon are presented. The purpose of this book is to emphasize the importance of the existence of the radioactive gas radon in the environment and to make this natural phenomenon a top issue because radon is included in class A human carcinogenesis. The chapters of the book show physical and chemical properties of radon and radon progeny; concentration, emanation, and transport of radon in ambient environments; detection of radon and radon progeny in different environments; passive and active radon measurement techniques; and calibration of a dosimeter for the detection of radon. This book will be of great importance to scientists from a wide range of research area on the phenomenon of radon and will be useful to those who are beginners in this area as well. Due to the impact of radon gas on health, the content of this book will be interesting to a wider audience.

This volume draws together the final outputs of the five-year UNESCO/IUGS/IGCP Project 571 and presents new data on radon in the built and natural environments, radon as a diagnostic tool of geophysical phenomena, reflections and recommendations on the future of radon research and a critique of radon's asserted use as a therapy. By considering all the aspects of radon as a health hazard and potential indicator of natural hazards, the project brought together the dispersed research (from universities, governmental and non-governmental bodies as well as commercial companies) on radon within an interdisciplinary context to facilitate scientific advancement and understanding. Through the establishment of working groups at regional and local levels and the development of research networks, a variety of international meetings were organized and a number of journal special issues published to disseminate the results. The scale of the project was global: scientists from over 20 European countries, plus countries in the Americas, Asia and the Middle East have been participants of the project. This volume results from UNESCO/IUGS/IGCP Project 571 `Radon, Health and Natural Hazards'. Radon has significant socio-economic relevance in the developed and developing worlds, primarily in terms of the indoor radon hazard but also certain geohazards. This volume presents a broad range of papers including methodological, technological and interpretative aspects, as well as case-study material.

In recent years, the perception of indoor radon as a relatively minor health issue has been radically altered: observations in Sweden, Canada, and the U.S. have revealed the high incidence of elevated radon levels in ordinary houses and the extreme hazard of inhaling radon decay products. These findings have lead to a wide range of activities and intensive research aimed at limiting human exposure to radon. This is one of the few books to provide a comprehensive, insightful analysis of the radon problem. Papers reflecting the most current research critically review all major aspects of this issue, each providing sufficient detail to be accessible to those who are technically trained but lack prior direct experience. Coverage includes the generation and migration of radon in source material, the physical and chemical behavior of radon, current evidence on the health effects and risk of exposure, and the strategic and tactical aspects of controlling exposures.

Radiation, radioactivity, radon: these are words that, since Hiroshima, the Cold War, and Three Mile Island, have conjured fear and fascination for many Americans. The threat of nuclear war, however, was always abstract at best, and the possibility of a meltdown was seen primarily as a localized catastrophe. Yet the danger of radon--an invisible, odorless gas that could seemingly attack any home and afflict its residents with a deadly cancer--struck home in the 1980s when whole neighborhoods were deemed unsafe and homeowners were forced to relocate, often at great expense. But how much of a threat does radon really pose to Americans? Is the government's aggressive policy toward this "silent killer" warranted? Indeed, is there a legitimate threat at all? These are the important questions Leonard A. Cole asks in this provocative and fascinating new book, and his answers are ones that all homeowners will want to understand. In clear, non-technical language, Cole dispels many of the myths surrounding radon as he makes recommendations for a coherent, reasonable environmental policy toward what is, certainly, a dangerous gas. But at what levels does radon become a health problem? From all the alarmist headlines ("Major Radon Peril Is Declared By U.S." screamed the New York Times in 1988), average Americans would never know that the threat of radon is much debated, among scientists as well as among government officials. They would never know that numerous European countries--with advanced environmental policies--see the radon levels found in homes and apartments as much less of a danger than we do. And they would never know that not even a single lung cancer death can be directly attributed to a radon-contaminated environment. As he carefully traces the development of the U.S.indoor radon policy, Cole illuminates the many scientific uncertainties that lie behind it, and challenges EPA's risk-cost assessment of radon levels. He shows, too, that no epidemiological study has confirmed that homeowners are at great risk, and exposes those who stand to gain from the policy decisions made in Washington. Since it is not caused by any industry, radon has been a politically convenient issue. Under the Reagan administration, for example, an aggressive radon policy proved an easy way to challenge the popular perception of an anti-environmental president. In the end, Cole convincingly argues for less strict radon regulations, and maintains that the average citizen must be involved in the decision-making process, and must be allowed to exercise her own informed judgment. Thoughtful and timely, Element of Risk illuminates one of the most important public policy issues of our time. It is a book homeowners and taxpayers, scientists and policymakers, will find essential reading.
