Abstract Objective Object Geothermal resource is very rich in central Shaanxi and is widely exploited presently. The object of the study is to know the effect of geothermal resource exploiting to indoor environment and people health. Methods The concentrations of radon and ions in geothermal water were measured by FD-125 Rn-analysis meter and Tracerlab crs-z-s ion analyzer, respectively. Results The measurement results indicat that the radon concentration is various in the geothermal water from different area and the radon concentrations in the water from Northwest University of Politics & Law, Luanzhen and fisheries of Dongdazhen are high with the maximum of 142.94 kBq·m-3. The ions concentration in the studied water samples are relatively high. Conclusion The usage of high radon geothermal water would cause radiation hazard to people and radon concentration is positive correlation with ion concentation. The radiation protection measurement of geothermal usage should be strengtherned.
