AB  - Radon is an odorless, radioactive gas formed from the breakdown of uranium and thorium. Chronic exposure to elevated radon (<SUP>222</SUP>Rn) decay product concentrations is recognized as health risk. The water used for drinking and other household uses can increase the indoor radon level because dissolved radon escapes from the water and gets into household air in the course of dishwashing showering and other water-using activities. Also, ingesting water with elevated levels of radon can present a risk for developing internal organ cancers. In this study radon concentrations of the 43 water samples have been measured by PRASSI system. The 4 samples have radon concentration higher than 11 Bq L<SUP>-1</SUP> as normal level. Similarly, the annual effective dose in stomach and lung per person has been evaluated in this research. According to the advised of WHO and the EU council none of the samples induced the total annual effective dose &gt;0.1 mSv year<SUP>-1</SUP>.
