Te-norm in phosphogypsum characterization and treatment
- Hot Laboratories and Waste Management Center, Atomic Energy Authority (Egypt)
The present work is directed to the characterization of the phosphogypsum (PG) solid waste which accompanying the production of phosphoric acid by the wet process in Abu Zaabal company for fertilizers and chemicals production in Egypt. Samples from PG were characterized radiometrically using both {gamma}- and {alpha}- spectrometric analysis and the different naturally occurring radionuclides present were identified. The main activity concentrations of such radionuclides were determined and the data obtained showed that this waste contains an enhanced level of some radionuclides especially Ra-226. Treatment investigations were experimented to reduce the enhanced activity level of Ra-226, which was found to exceed that permitted by the international regulations. (authors)
