Book Description :

Whenever radioactivity is released to the atmosphere, for example by the detonation of nuclear weapons or the testing of nuclear weapons or from nuclear reactor accidents that fraction of it which remains airborne for more than a few hours is liable to be attached to aerosol particles. The resulting radioactive aerosols are carried by atmospheric mixing processes until they settle out or are scavenged by precipitation. The radiation exposure pathway of maximum concern to humans is by inhalation of aerosols and their deposition in the respiratory tract. In this context, it is important to note that radioactive aerosols are commonly of natural origin alos. In particular, the associated radionuclides can be of natural terrestrial origin, such as the decay products of radon gas, or they can e cosmogenic, such as beryllium-7. The exposure of miners of uranium and other ores and minerals to radon and its aerosol-borne decay products is of major significance. The book describes the formation of aerosols, their aerodynamic size distribution, their atmospheric residence time, their sampling and measurement, the range of radioactive aerosols found and studied thus far, including man-made nuclides and radon decay products and their interaction with man, including deposition in the lung and subsequent health effects. Advanced level science handbook for researchers, scientists and academics Covers all aspects of radiation exposure in humans, including subsequent health implications Presents the latest findings and analysis in this highly topical area

Book Description :

This book is intended as an introduction to radioactivity and aerosols for the scientifically literate reader who has had no previous exposure to either of these subjects. Although its main focus is radioactive aerosols, on the road to this subject I provide short, somewhat independent introductions to both radioactivity and aerosols, with some emphasis on experimental aspects. The audience I have in mind is upper-level undergraduates or beginning graduate students with a minimum background of introductory college courses in physics, chemistry, and calculus. This book may also be useful to "crossover" professional- professionals in other fields of science and engineering, for example biology or geoscience, who would like a step-by-step introduction to this subject matter from the physical science perspective. In writing this book I have been sensitive to requests and suggestions from students who need some background in this subject matter but will probably not specialize in it. These students are bright, but busy, and they sometimes feel overwhelmed by the mass of information in advanced, comprehensive texts. No matter how noble the intentions of the authors (or the teachers assigning the books!), these students often do not have time to read such books through cover to cover, and they fmd it difficult to pick out a coherently-connected subset of the material. Furthermore, modern students studying an interdisciplinary subject like radioactive aerosols are likely to be more diversified than ever, in educational background, in interests, and in preparation.

Book Description :

Aerosols influence many areas of our daily life. They are at the core of environmental problems such as global warming, photochemical smog and poor air quality. They can also have diverse effects on human health, where exposure occurs in both outdoor and indoor environments. However, aerosols can have beneficial effects too; the delivery of drugs to the lungs, the delivery of fuels for combustion and the production of nanomaterials all rely on aerosols. Advances in particle measurement technologies have made it possible to take advantage of rapid changes in both particle size and concentration. Likewise, aerosols can now be produced in a controlled fashion. Reviewing many technological applications together with the current scientific status of aerosol modelling and measurements, this book includes: • Satellite aerosol remote sensing • The effects of aerosols on climate change • Air pollution and health • Pharmaceutical aerosols and pulmonary drug delivery • Bioaerosols and hospital infections • Particle emissions from vehicles • The safety of emerging nanomaterials • Radioactive aerosols: tracers of atmospheric processes With the importance of this topic brought to the public’s attention after the eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely, concise and accessible overview of the many facets of aerosol science.

Book Description :

Study of the efficiency of filters for the retention of natural airborne radioactive aerosols has shown that the paricles with which the radioactivity of the short-lived radon daughters is associated have greater ability to penetrate the variousfilter media than has the fission product debris in the atmosphere; therefore the former is associated with aerosols of smaller size. A preliminary evaluation of the techniques of employing packs of filters of different retentivity characteristics to determine the particle size and/or particle size distribution of radioactive aerosols has been made which indicates the feasibility of the method. It is recommended that a series of measurements be undertaken to determine the relative particle size distribution of RaB+C as a function of time, season and weather, and the size ditribution of fission products as a function of the above parameters and the source of the debris.

Book Description :

Although the field of radioactive air sampling has matured and evolved over decades, it has lacked a single resource that assimilates technical and background information on its many facets. Edited by experts and with contributions from top practitioners and researchers, Radioactive Air Sampling Methods provides authoritative guidance on measuring airborne radioactivity from industrial, research, and nuclear power operations, as well as naturally occuring radioactivity in the environment. Designed for industrial hygienists, air quality experts, and heath physicists, the book delves into the applied research advancing and transforming practice with improvements to measurement equipment, human dose modeling of inhaled radioactivity, and radiation safety regulations. To present a wide picture of the field, it covers the international and national standards that guide the quality of air sampling measurements and equipment. It discusses emergency response issues, including radioactive fallout and the assets used to assess airborne radioactive emergencies. The book includes a comprehensive series of air sampling methods for commonly encountered radioactive isotopes in the industrial environment that detail the steps to conducting a proper air sampling study. With coverage of fundamental air sampling techniques and practical knowledge, the book provides insight into the contemporary thinking of experts, the maturity of the field, and its deep literature base. Building a bridge between the science behind air sampling and its practice, it supplies the know-how required to achieve technically rigorous air sampling data.

Book Description :

Applications of Nuclear and Radiochemistry is a collection of articles focusing on contemporary applied research on radioactive isotopes. The monograph is based on the Second Chemical Congress of the North American Continent, held at Las Vegas, Nevada in August 1980. The book contains articles on developments in nuclear chemistry and radiochemistry, emphasizing the topic of radiopharmaceutical chemistry. The text is composed of two parts, wherein the first part is comprised of papers dealing with advances in the production of radionuclides for nuclear medicine, in the synthesis of labeled pharmaceuticals, and in the design and use of specific diagnostic agents. These sections cover research areas on machines used for research, such as compact accelerators, positron emission, and single photon tomographs. Emphasis is given to the radiochemistry and design of radiopharmaceuticals for receptor studies and for determining physiological function and metabolism of the brain, heart, and tumors. The second part examines contemporary advances including the impact of radiochemistry in China pertaining to the fallout from Chinese nuclear tests. This part also contains a section covering a list of uncommon topics. The text is of interest to nuclear scientists, academicians in the field of radiology and radiochemistry, researchers in nuclear medicine, nuclear engineers, and environmental researchers.
