Self-cleaning in an estuarine area formerly affected by 226Ra anthropogenic enhancements: numerical simulations
(Elsevier, 2005)
A numerical model of the Odiel–Tinto estuary (Spain) has been developed to study the self-cleaning process that was evidenced from 226Ra measurements in water and sediments collected in the period 1999–2002, after direct ...

Self-cleaning in an estuarine area formerly affected by 226Ra anthropogenic enhancements
(Elsevier, 2004)
The estuary of the Odiel River has been affected by both direct discharges of phosphogypsum (radium enriched industrial waste) and dissolution and weathering of the exposed piles where this radium enriched waste was ...

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 ...

Contamination and restoration of an estuary affected by phosphogypsum releases
(Elsevier, 2009)
The Huelva Estuary in Huelva, Spain, has been one of the most studied environmental compartments in the past years from the point of view of naturally occurring radioactive material (NORM) releases. It has been historically ...
