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.

Geology, one of the basic natural sciences, is proving to be of outstanding importance in solving problems relating to:agricultureexploitation of the Earth's mineral resources environmental issuessoil preservationwater energy and other resourcesprotection against natural disasters (landslides, floods, volcanic eruptions and earthquakes) as well as human health. The main objective of the book Medical Geology: Effects of Geological Environments on Human Health is to show how the geological environment affects human health and to explore preventative methods for improvement.This monograph consists of the following five segments:IntroductionGeological and other factors and their influence on the human health Subject, tasks and methods of geomedical disciplineRegional medical geologyApplied medical geology The topics covered in this book will be of interest to a wide circle of readers, including geologists, doctors, biologists, ecologists, planners and many others who are dedicated to the quality and protection of human health.
