Alpha radiometry of uranium in surface and ground waters by liquid scintillation counting after separation of the radionuclide by cation exchange
(2008)The alpha radioactivity of surface and ground water samples has been determined by liquid scintillation counting (LSC) after chemical preparation of the samples by cation exchange using the Chelex 100 resin. The method ...

Boron in groundwaters of Nicosia (Cyprus) and its treatment by reverse osmosis
(2007)Boron levels in groundwaters of Nicosia have been determined, compared to previous concentration data and correlated to the concentration of other chemical species contained in the groundwaters under investigation. According ...

Determination of aquatic radon by liquid scintillation counting and airborne radon monitoring system
(2008)This paper presents an airborne radon monitoring (RM) system for aquatic radon determination after out-gassing of radon from the aqueous sample and compares this method with the standard ASTM method for radon analysis in ...

Article
Lithological and seasonal variations in radon concentrations in Cypriot groundwaters
(2010)The paper presents and discusses radon activity concentrations in Cypriot groundwater systems as a function of the background lithology and seasonal/meteorological conditions using an airborne radon monitoring system (ARM) ...

Article
Radon levels in Cyprus
(2003)Radon levels in atmospheric and aquatic systems in Cyprus have recently been measured using the radon monitor Alpha Guard. Indoor and outdoor radon levels were obtained in situ, whereas analysis of radon concentrations in ...

Article
Seasonal variation of the alpha-radioactivity concentration in natural water systems in Cyprus
(2011)The study deals with the seasonal variation of the total alpha-radioactivity and the U-238/234 radioactivity concentration of ground waters in Cyprus. The radiometric measurements were performed after pre-concentration and ...

Article
Seasonal variation, chemical behavior and kinetics of uranium in an unconfined groundwater system
(2014)The seasonal changes in the concentration of uranium in an unconfined groundwater system in Cyprus have been investigated and compared to corresponding changes of boron and salinity, to better understand the chemical ...

Article
Uranium analysis in Cypriot groundwaters by total alpha-radiometry and alpha-spectroscopy
(2011)Two different alpha-radiometric methods (e.g. alpha-spectroscopy and alpha-particle counting) have been applied to the determination of uranium in Cypriot groundwater samples after separation of the radionuclides by cation ...

Uranium levels in Cypriot groundwater samples determined by ICP-MS and α-spectroscopy
(2013)The uranium concentration and the isotopic ratio 238U/234U have been determined in Cypriot groundwater samples by ICP-MS after ultrafiltration and acidification of the samples and α-spectroscopy after pre-concentration and ...
