dc.description.abstract | 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 local
geological conditions. Mining legacy in Sweden produced hundreds of these pit lakes and most of them are used
for recreational purposes in the southern part of the country. In this paper, one pit lake was selected for having
enhanced levels of natural radionuclides. Physico-chemical parameters (temperature, pH, oxidation-reduction
potential, dissolved oxygen and depth), elemental composition (via Inductive Coupled Plasma Mass Spectrometry) and radiometric characterization (via alpha spectrometry of 226Ra, 210Po and 210Pb) were carried along the
depth of a 60 m depth pit lake, with the main aim to describe how natural radionuclides and elements behaves
with depth in a non-uraniferous pit lake.
Based on observed changes in physico-chemical parameters, a thermocline and a chemocline region were
identified at around 10 and 30 m depth respectively. Concerning radionuclides, 226Ra ranged from 75 ± 3 up to
360 ± 12 mBq/kg while 210Po ranged from 11 ± 1 up to 71 ± 3 mBq/kg. 210Pb distribution with depth was also
determined via secular equilibrium with 210Po after 2 years and also stable Pb was measured. Disequilibrium 226Ra-210Pb was found and the residence time of 210Pb in the water column was assessed. Additionally, different
vertical distributions between 210Pb and Pb were found which points out different sources for different lead
isotopes in the water body. | es |
