Measuring and modelling the radiological impact of a phosphogypsum deposition site on the surrounding environment.
Phosphogypsum (PG) is a waste product (residue) from the production of phosphoric acid characterized by technologically enhanced natural radioactivity. Croatia's largest PG deposition site is situated at the edge of Lonjsko Polje Nature Park, a sensitive ecosystem possibly endangered by PG particles. This field study investigates two aspects relevant for the general radiological impact of PG: r...
متن کاملRadiological Impact of the Application of Phosphogypsum in Civil Construction: an Overview of Brazilian Studies
In the last decades considerable attention has been given to naturally occurring radioactive material (NORM). Within this frame, of particular concern is the phosphate fertilizer industry. In Brazil, four main industries (Ultrafertil, Copebrás, Fosfertil and Bunge Fertilizantes) are responsible for the production of 1.2x10 6 tons per year of P2O5. Phosphogypsum is the by-product of the phosphor...
متن کاملThe radiological impact of phosphogypsum stockpile in Wiślinka (northern Poland) on the Martwa Wisła river water
The aim of this work was to determine the concentrations of uranium (234U, 235U, 238U), polonium (210Po) and lead (210Pb) radioisotopes in water samples and to explore the impact of the phosphogypsum stack on the Martwa Wisła waters. The 238U, 210Po and 210Pb concentrations in analyzed water samples reached maximum values of 11.7 ± 0.3, 2.0 ± 0.1 and 3.2 ± 0.1 mBq L-1 and activity ratios were m...
