A natural radioactivity in thermal water was investigated based on 19 selected waters from Poland. The analysed results show that the radionuclides’ concentrations study vary over a wide range. temperature of varies above 20 °C to 80 °C. are characterised by different mineralisation, chemical compositions, and belong hydrochemical types. There is good correlation between depths aquifer formatio...

The vertical activity concentration distributions of the radium isotopes, 226 Ra and 228 Ra, which are useful as radiotracers, were obtained for first time in western Subarctic Pacific Gyre (WSAG). It was possible to detect short-lived present from surface 400 m depth by analyzing large seawater samples. Low high concentrations layer WSAG strongly influenced upwelled deeper water with nutrients...

Submarine groundwater discharge (SGD) is now recognized as an important process of the hydrological cycle worldwide and plays a major role conveyor dissolved compounds to ocean. Naturally occurring radium isotopes (223Ra, 224Ra, 226Ra 228Ra) are widely employed geochemical tracers in marine environments. Whilst Ra were initially predominantly applied study open ocean processes fluxes across con...

An investigation of the potential environmental and health impacts in the immediate aftermath of one of the largest coal ash spills in U.S. history at the Tennessee Valley Authority (TVA) Kingston coal-burning power plant has revealed three major findings. First the surface release of coal ash with high levels of toxic elements (As = 75 mg/kg; Hg = 150 microg/kg) and radioactivity (226Ra + 228R...
