Characterization of source rocks and groundwater radioactivity at the Chihuahua valley
(Sociedad Mexicana de Física, 2007)
As part of a scientific research project about alpha radioactivity in groundwater for human consumption at the Chihuahua City, the charac-terization of rock sources of radioactivity around de Chihuahua valley was developed. ...

Radiactive particle biotic and abiotic processes
(2022-09-09)
In ecosystems affected by the presence of radioactive particles, it is imperative to obtain information regarding transformation processes that affect them in order to properly evaluate not only their behaviour, but also ...

Measurement of 210Pb and its application to evaluate contamination in an area affected by NORM releases
(American Institute of Physics, 2008-08-07)
Liquid scintillation counting (LSC) is an easy and straightforward technique, and combined with its low limit of detection, makes it a powerful tool for both routine and low level measurements that can be applied to 210Pb ...

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 ...

Natural radionuclides (NORM) in a Moroccan river affected by former conventional metal mining activities
(Elsevier, 2019)
The main aim of this work was to determine the levels of multiple natural radionuclides in an aquatic system (Moulouya river, Morocco) impacted by multiple abandoned Zinc and Lead mines. 238U, 234U, 232Th, 230Th and 210Po ...

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 ...

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 ...
