The radioactivity parameters in the food chain - legislation, control and critical points

Abstract Radioactivity, whether natural or artificial, today constitutes a significant segment in the process of protecting human and animal health. Natural radioactivity is an integral part our ecological system, so it has long been present food we eat. However, intensive industrial processes some areas have disturbed balance thus introduced into environment radionuclides quantities that can affect quality life state environment. On other hand, artificial reach only case accident situations nuclear facilities. In era far, two accidents, Chernobyl 1986 Fukushima 2011, affected globally with impact. Consequently, system monitoring was introduced, which includes foodstuffs as well feed. The paper describes sources radioactive contamination most critical raw materials products chain, review current legislation.
