Radioactivity of phosphate mineral products

Abstract

The phosphate industry is one of the biggest polluters of the environment with uranium. Different products are derived after processing phosphoric ore, such as mineral and phosphate fertilizers and phosphate mineral supplements (dicalcium-and monocalcium phosphate) for animal feeding. Phosphate mineral additives used in animal food may contain a high activity of uranium. Research in this study should provide an answer to the extent in which phosphate mineral products (phosphate fertilizer and phosphate mineral feed additives) contribute to the contamination of soil, plants and animals.

Fosfatna industrija predstavlja jedan od najvećih zagađivača životne sredine uranijumom. Preradom fosforne rude dobija se veliki broj različitih proizvoda, od kojih su posebno značajni fosfatna mineralna đubriva i fosfatni mineralni dodaci (di- i monokalcijum fosfat). Fosfatni mineralni dodaci koji se koriste u smešama za ishranu životinja mogu sadržati visoke aktivnosti uranijuma. Istraživanja u ovom radu treba da pruže odgovor u kojoj meri fosfatni mineralni proizvodi (fosfatna đubriva i fosfatni mineralni dodaci stočnoj hrani) doprinose kontaminaciji zemljišta, biljaka i životinja.
