A short-time method to measure the radon potential of porous materials
(Elsevier, 2009)
The radiological risk associated with the use of solid materials has been traditionally established according to their radon exhalation rates, the accumulation chamber technique being the most widely used for the ...

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 ...

A simple method for efficiency calibration of HPGe detectors in gamma-spectrometric measurements
(Elsevier, 2001)
In this paper a simple, rapid and general method for g-ray efficiency calibration of Ge detectors for environmental samples is presented. This method is based on the use of an active natural solid sample with several ...

Evaluación de la Seguridad Alimentaria y Radiológica en la Aplicación del Fosfoyeso Como Enmienda de Suelos Agrícolas en las Marismas del Guadalquivir
(2006)
The main goal of this Project has been the radiological and alimentary assessment of the agriculture use of phosphogypsum (PG), a by-product of the fertilizer industry, as Ca-amendment in reclaimed salt-marsh soils in ...

Natural occurring radionuclide waste in Spain: the Huelva phosphogypsum stacks case
(2009-11)
In this paper, the historical evolution in the management of the wastes generated by one paradigmatic NORM industry devoted to the production of phosphoric acid by ...

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 ...

Characterization of Porous materials as radon source and its radiological implications
(AIP Publishing, 2008)
In this work, a magnitude is proposed in order to compare the potential radiological risk due to radon exposition generated by different materials, and a method based in the ^^^Rn accumulation technique ...

A self-sufficient and general method for self-absorption correction in gamma-ray spectrometry using GEANT4
(Elsevier, 2007)
This paper presents a self-sufficient and general method for measurement of the activity of low-level gamma-emitters in voluminous samples by gamma-ray spectrometry with a coaxial germanium detector. Due to self-absorption ...
