Natural radioactivity and element characterization in pit lakes in Northern Sweden
(Plos, 2022)
Northern Sweden has been the object of intense metal mining in the last decades producing several water-filled open-pits, or pit lakes. Most of these pit lakes have been limed to maintain a good water quality and to prevent ...

The enhanced naturally occurring radioactivity of negative ion clothing and attendant risk
(MDPI, 2021-06-10)
The study investigates commercially available negative ion clothing, and evaluations are made using gamma-ray spectroscopy and Geant4 Monte Carlo simulations. Observed to contain naturally occurring radioactive material ...

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 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 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 ...
