A comparison of 210Pbxs, 137Cs, and Pu isotopes as proxies of soil redistribution in South Spain under severe erosion conditions
(Springer, 2023-06-01)
Purpose The use of fallout radionuclides as proxies for the study of soil redistribution processes in semiarid environments of Southern Spain has been restricted to 137Cs. The potential and limitations of alternative ...

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 ...

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 ...

Levels of radionuclide concentrations in benthic invertebrate species from the Balearic Islands, Western Mediterranean, during 2012–2018
(Elsevier, 2019-12)
Baseline levels of radionuclides in the marine environment of the Balearic Islands in Western Mediterranean have not been reported in literature. Because of their ecological role and acknowledged sensitivity to pollutants, ...

Phosphogypsum amendments and irrigation with acidulated water affect tomato nutrition in reclaimed marsh soils from SW Spain
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2014)
Phosphogypsum (PG) is a by-product of the P fertilizer industry usually valorised as amendment for acidic and sodic soils. This work was aimed to study the effects of PG on nutrient uptake by industrial tomato plants in ...

Optimization of AlphaGuard AquaKIT set-up for analysis of radon in water using stainless-steel bottles and its validation through IAEA standard samples
(Elsevier, 2021-03)
In this study, a system composed of an ionization chamber AlphaGUARD (PQ 2000), an AquaKIT set and an AlphaPUMP was calibrated to measure 222Rn in water. First, the system was checked for leakages using a NIST traceable ...

Intercalibration of selected anthropogenic radionuclides for the GEOTRACES Program
(American Society of Limnology and Oceanography, 2012)
As part of the GEOTRACES Program, six laboratories participated in an intercalibration exercise on several anthropogenic radionuclides of interest. The effort was successful for 239,240Pu activity, 240Pu/239Pu isotope ...

The use of 99mTc as a tracer in the determination of 99Tc by ICPmass spectrometry
(2000)
The aim of this paper is to carry out a deep study on the possibilities of using 99mTc from 99Mo-99mTc clinical isotope generators to trace the radiochemical separations for 99Tc measurements by ICP-MS. By appropriately de®ning ...

Analysis of a major Aeolian dust input event and its impact on element fluxes and inventories at the DYFAMED site (Northwestern Mediterranean)
(Elsevier, 2020-06)
Continental dust can be suspended and transported by the wind, reaching seawater masses far away from its source. The deposition of the aerosols on the ocean surface can alter the abundance of chemical species in the ...

Baseline activity concentration of ²¹⁰Po and ²¹⁰Pb and dose assessment in bivalve molluscs at the Andalusian coast
(Elsevier, 2018-08)
In this study, the activity concentrations of ²¹⁰Po and ²¹⁰Pb were determined in different types of bivalve molluscs sampled during the period of May 2014–June 2015 along the Andalusian littoral. Radioactivity con- centrations ...
