Radon groundwater in a radon-prone area: possible uses and problems: an example from SW part of Kłodzko Valley, Sudetes, SW Poland.

The paper describes research aimed at expanding scientific knowledge of radioactive isotope Rn occurrence in groundwaters flowing in crystalline rocks, including its spatial and temporal changes. The research, conducted in an area characterized by medium radon potential, was intended to determine the values of Rn activity concentration in groundwater in this type of areas. The Rn activity concentration in groundwaters discharged from investigated springs oscillated between 35.
