Occupational, public and environmental radiological impact caused by the phosphoric acid industry: the case of Huelva (Spain)
(Intech, 2017)
The production of phosphate fertilizers usually uses as raw material sedimentary phosphate rock, which contains enhanced concentrations from U‐series radionuclides about 10–100 times higher than unperturbed soils. ...

129I, 236U, 239Pu and 240Pu profiles in a peatbog from the Southern Hemisphere
(2016)
129I, 236U, 239Pu and 240Pu isotopes have been analyzed in the different layers of a peatbog core collected in Madagascar Island (South Hemisphere) and representing at least the last 100 years ...

226Ra, 210Po and lead isotopes in a pit lake water profile in Sweden
(Elsevier, 2020-11)
A pit lake arises as a consequence of anthropogenic activities in opencast mining areas. These water bodies may be enriched in hazardous stable contaminants and/or in naturally occurring radionuclides depending on the ...

A new approach to process planktonic foraminifera for radiocarbon measurements
(2016)
Carbonate shells from foraminifera are often analyzed for radiocarbon to determine the age of deep-sea sediments or to assess radiocarbon reservoir ages. The Centro Nacional de Aceleradores (CNA) is equipped for the AMS ...

210Po levels and distribution in different environmental compartments from a coastal lagoon. The case of Briozzo lagoon, Uruguay
(Elsevier, 2020)
This paper presents the levels and distribution of 210Po in different compartments of a coastal lagoon on the east coast of Uruguay (South America). Activity concentrations of 210Po have been obtained in different ...

A three-dimensional model for the dispersion of radioactive substances in marine ecosystems: application to the Baltic Sea after the Chernobyl disaster
(Elsevier, 2004)
A 3-D dispersion model has been developed to simulate the dispersion of nuclear contaminants in marine ecosystems. This model is characterized by presenting high spatial resolution, by taking into account the possible ...

A study of the Suess effect using a raised peat bog as historical archive
(2011-03)
The radiocarbon content in a peat core from Gävle, Sweden, 61.0 oN, 17.0 oE, has been studied. This is a raised peat bog which only receives material from atmospheric deposition. There has been an increased ...

A method for the determination of counting efficiencies in gamma-spectrometric measurements with HPGe detectors
(Elsevier, 1996)
In this paper a general method for y-ray efficiency calibration is presented. The method takes into account the differences of densities and counting geometry between the real sample and the calibration sample. It is based ...
