Occupational dosimetric assessment (inhalation pathway) from the application of phosphogypsum in agriculture in South West Spain
(Elsevier, 2009)
Phosphogypsum (PG) has been traditionally applied as Ca-amendment in saline marsh soils in SW Spain, where available PG has 710 ± 40 Bq kg−1 of 226Ra. This work assesses the potential radiological risk for farmers through ...

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 ...

Radionuclides in the environment in the south of Spain, anthropogenic enhancements due to industry
(Sociedad Mexicana de Física, 2007-02)
Levels of natural radionuclides in the environment are affected by human activities in the South of Spain. Industry wastes, such as phosphogypsum, have been released to an estuary since sixties until 1997. Nowadays the ...

Transfer of Cd, Pb, Ra and U from Phosphogypsum Amended Soils to Tomato Plants
(Springer, 2009)
About 170 million tons of phosphogypsum (PG) are annually generated worldwide as a by-product of phosphoric acid factories. Agricultural uses of PG could become the main sink for this waste, which usually contains significant ...

The cumulative effect of three decades of phosphogypsum amendments in reclaimed marsh soils from SW Spain: 226Ra, 238U and Cd contents in soils and tomato fruit
(Elsevier, 2008)
Phosphogypsum (PG), a by-product of the phosphate fertiliser industries, has been applied as soil amendment to reduce Na saturation in soils, as in the reclaimed marsh area from SW Spain, where available PG has a typical ...
