Über dieses Buch

The book deals with various consequences of major nuclear accidents, such as in 1986 in Chernobyl and in 2011 in Fukushima. The public is extremely interested in learning more about the movements and risks posed by radiation in the environment related to food supply and food safety. Radionuclides are found in air, water, soil and even in us not only after nuclear accidents because they occur also in nature. Every day, we ingest and inhale radionuclides in our air and food and the water. This book provides a solid underpinning of the basic physical-chemistry and biogeochemistry of naturally occurring and anthrop radioactivity. The mechanisms of radioactive element transfer in the atmosphere, tropospheric and stratospheric diffusion of radioactivity, environmental contamination from accidents and the impact of atmospheric pollution on the food chain, soil and plants, are analyzed and the analytical methods are illustrated. The question of natural radioactivity concentration in building materials is addressed too. While the book contains many case studies and data for Greece, it is of general value. It contributes to the development of international environmentally safe standards and economically reasonable standard regulations based on justified radiological, social and economical legislation concepts.


Chapter 1. Status of the Problem
Fokion K. Vosniakos
Chapter 2. Methods and Materials of Analysis
The research work has been carried out in Greece, mainly in the region of Northern Greece as well as its neighboring geographical regions. The research work aforesaid has been made during the period 1989–1998.

Chapter 3. Results and Discussions
The measuring method for determining the radioactivity in the air is based on an air-filtering method where the atmospheric air is pumped out and analyzed by γ-spectroscopy, in order to measure the presence of radioactive isotopes.

Chapter 4. General Discussion on the Results
The results obtained from the studies carried out present information of great interest about the radioactive contamination in Greece. In addition, correlations were found between radioactive elements and nuclides of great interest upon reprocessing the data. There has been demonstrated the dependence of their content and half-life on atmospheric physical parameters (temperature, air speed, relative humidity), composition and structure of the soil, reology of the basic substances of foods and plants, active acidity (pH), etc.

Chapter 5. Basic Conclusions
The results obtained from the research carried out about the radioactive transfer air, soil, plants, and food give ground to the following basic conclusions
