RADON AND RADIUM MEASUREMENTS OF ESKIsEHIR SPA WATERS.

In this study, radon and radium concentrations of spa waters around Eskisehir county were measured using E-Perm method. Radon and radium concentrations were determined between 0.75 ± 0.18 and 8.98 ± 0.80 Bq l-1, 3.44 ± 0.34 and 70.63 ± 4.13 mBq l-1, respectively. At the sampling time, indoor and outdoor background gamma radiation, pH, water temperature and conductivity were measured for the each sampling point. The annual effective dose a person is exposed to as a result of water consumption has been calculated for radon and radium. In addition, the dose exposed as a result of the transfer of radon in the water to the air and the inhalation of this air was also calculated.
