Extensive radioactive characterization of a phosphogypsum stack in SW Spain: 226Ra, 238U, 210Po concentrations and 222Rn exhalation rate
(Elsevier, 2009)
Phosphogypsum (PG) is a by-product of the phosphate fertilizer industries that contains relatively high concentrations of uranium series radionuclides. The US-EPA regulates the agriculture use of PG, attending to its 226Ra ...

Phosphogypsum Amendment Effect on Radionuclide Content in Drainage Water and Marsh Soils from Southwestern Spain
(Wiley, 2003)
Phosphogypsum (PG) is a residue of the phosphate fertilizer industry that has relatively high concentrations of 226Ra and other radionuclides. Thus, it is interesting to study the effect of PG applied as a Ca amendment on ...

239Pu sorption by suspended matter from Hueznar reservoir (southern Spain): Experimental and modelling study
(E. D. P. Sciences, 2005)
Kinetic transfer coefficients are important parameters to understand and reliably model the behaviour of non-conservative radionuclides in aquatic environments. This report pertains to a series of radiotracer experiments ...

Evaluation of the radioactive impact of the phosphogypsum wastes used as amendment in agriculture soils
(E. D. P. Sciences, 2005)
Some 3x109 kg of phosphogypsum (PG) wastes are annually generated by two fertiliser-production factories in Huelva (south-western Spain). PG has relatively high concentrations of 226Ra and other radionuclides, with an ...

Application of a liquid scintillation counter to the measurement of tracing radioactivity in experiments on suspended matter uptake in aquatic environments
(E. D. P. Sciences, 2002)
The experiments on the study of the kinetic transfer coefficients of conservative and non-conservative radionuclides, in aquatic environments, need to determine radionuclide activity in large number of samples. Different ...

Experimental and modelling study of artificial radionuclides (239Pu, 241Am and 99Tc) uptake by suspended matter in environmental waters located in the south of Spain
(E. D. P. Sciences, 2002)
The interest on transfer coefficients studies have increased recently, since they are important parameters required understanding and reliably modelling the dispersion of conservative and non-conservative radionuclides in ...

Radioactive impact in sediments from an estuarine system affected by industrial wastes releases
(Elsevier, 2002)
A big fertilizer industrial complex and a vast extension of phosphogypsum piles (12 km2), sited in the estuary formed by the Odiel and Tinto river mouths (southwest of Spain), are producing an unambiguous radioactive ...
