My research focuses on groundwater flow systems and the water chemistry chracteristics of different orders of flow systems.

My research focuses on the most commonly occurring radioactive isotopes in groundwater: uranium, radium and radon. Due to their different physical and chemical properties, they are typical for different segments of groundwater flow paths and different regime regions. They can therefore be used as natural tracers for characterising groundwater flow systems and the interaction between surface water and groundwater. Since drinking water is supplied almost 100% from groundwater and mineral water originates 100% from groundwater, the presence of natural radioactive isotopes in groundwater is also an important drinking water quality parameter. In our research, we are working togehter with waterworks and the National Centre for Public Health and Pharmacy to understand the origin of elevated levels of natural radioactivity in groundwater-derived drinking water using hydrogeological methods. For the alpha spectroscopic measurement of uranium and radium, we use selectively adsorbing Nucfilm discs. This technique is exclusively applied in Hungary in ELTE.
