	This study investigates the application of NaP1 zeolite, synthesized hydrothermally from F-class fly ash, for treating radium-contaminated mine water. The objective was to assess the efficiency of NaP1 zeolite in removing radium ions from real mine water samples. Three samples with high concentrations of 226Ra and 228Ra and total dissolved cation contents ranging from 48.9 to 89.0 g/L were treated using sequential batch and fixed bed experiments. The NaP1 zeolite demonstrated high treatment efficiency for radium-sulfate and radium-strontium water, with removal rates of 97 % and 82 % for the 1st liter, and 54 % for the 53th and 9th liters, respectively. However, for radium-barium water, the maximum treatment efficiency was 45 % for the 1st liter, dropping to 0 % after 4th liter. This decline was attributed to the competitive adsorption of barium ions, which reduced the radium removal efficiency more rapidly than in the other water types. An additional experiment with synthetic barium water confirmed that 10 g of NaP1 zeolite adsorbed 1 g of Ba from one liter of distilled water. These results highlight the potential of NaP1 zeolite for radium removal in certain contexts, although its efficiency may be hindered by the presence of competing ions such as barium
