Ausgehend von der Frage, inwieweit Niedrigdosisstrahlung gesundheitsgefährdend ist oder sogar auch positive Auswirkungen hat - wie bei einigen Heilverfahren erhofft - wurde das Problem Niedrigdosisstrahlung und Gesundheit von verschiedenen Seiten beleuchtet. Neben Statistiken zur Krebshäufigkeit in der Nähe von Wiederaufbereitungsanlagen oder zur Säuglingssterblichkeit nach Strahlenexposition wird besonders auch über Zusammenhänge zwischen Radonkonzentration und Gesundheitsbeeinträchtigungen berichtet. Da Radon in erhöhtem Maße beim Uranabbau und bei der Uranaufarbeitung anfällt, kommt es durch Abraumhalden oder Verwendung von Abraummaterial im Straßen- und Häuserbau zu einer langfristig erhöhten "natürlichen" Strahlungsbelastung. Erörtert werden in diesem Zusammenhang weiterhin Aspekte wie Strahlenschutz, Atomrechtssetzung, Sanierungsproblematik sowie ethische Gesichtspunkte. ... Read more

Product Description
Exposure to radon gas, which is present in the environment naturally, constitutes over half the radiation dose received by the general public annually. At present, the most widely used method of measuring radon concentration levels throughout the world, both in dwellings and in the field, is by etched track detectors - also known as Solid State Nuclear Detectors (SSNTDs). Although this is the most widely used method and is also the simplest and the cheapest, yet there is at present no book available on the market globally, devoted exclusively or largely to the methodology of, and dealing with the results obtained by, the SSNTD technique. The present book fills this important gap in the coverage of radon measurements. Individual chapters of the book are contributed by some of the most prominent and active research workers in the world in the SSNTD discipline as well as in the field of radon measurements. ...

Product Description
This book deals with the reliable verification of the accuracy of approximate solutions which is one of the central problems in modern applied analysis. After giving an overview of the methods developed for models based on partial differential equations, the author derives computable a posteriori error estimates by using methods of the theory of partial differential equations and functional analysis. These estimates are applicable to approximate solutions computed by various methods. ... Read more

Product Description
Ever more attention has been focused on naturally occurring radiation, thanks to the shift of public concern and scientific interest from high to low-level radiation in recent years. There are many places in the world that are known to have high levels of terrestrial background gamma radiation as well as highly concentrated radon and their decay products in the air, soil and drinking water. Various scientific investigations have been conducted in those areas to collect information on radiation doses and their health effects, contributing greatly to advancing our knowledge. In recent years, technologically enhanced naturally occurring radioactive material (TENORM) has also attracted attention. The 6th International Conference on High Levels of Natural Radiation and Radon Areas was held in Osaka, Japan from September 6-10, 2004, for the purpose of exchanging information and experience regarding investigations in this field. These proceedings contain more than 100 papers presented at the * Risk assessment, radiation protection, environmental transfer pathways and ecological impacts * Dosimetry of natural-radiation, including radon, thoron, and cosmic rays, and its technological aspects, e.g., individual dosimetry and retrospective measurements ...
