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 ...

Efficiency calibration and optimization of a liquid scintillation spectrometer for low level 55Fe and 63Ni measurements
(Elsevier, 2023-11)
An experimental study on the counting efficiency, background, and Lower Limit of Detection (LLD) of a liquid scintillation spectrometer was carried out for establishing a measurement technique suitable for low level activity ...

Time evolution of activity concentration of natural emitters in a scenario affected by previous phosphogypsum contamination
(2008-09)
The estuary formed by the confluence of Tinto and Odiel river-mouths is located in the South of Spain, close to Huelva town. This estuary has been deeply studied through the years because it ...

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 ...
