Water samples for radon-gas analyses were collected from springs in and around the town of Seydişehir. Radon concentration in the spring water has been measured using the AlphaGUARD PQ 2000PRO radon detector. Radon activity results varied from 1.85 to 99.27 Bq l-1. The radon level at the measurement points could have been controlled by local geological conditions (i.e. faults) and human activities. We also calculated annual effective doses resulting from the consumption of these water samples.
