Abstract
The radon exhalation rate in term of area was variable (10.4-52.1 mBq.m -2 .h -1 ) with the average value (30.1 mBq.m -2 .h -1 ) while the radon exhalation rate in term of mass was variable (1.09-5.45 mBq.kg -1 .h -1 ) with the average value (3.15 mBq.kg -1 .h -1 ) and radium concentration is varied (0.144-0.722 Bq.kg -1 ) with the average value (0.417 Bq.kg -1 ). The annual effective dose of radium for three population groups was carried out, and lifetime risk assessment was about 10 -4 when used this water as a drinking water. The results compared with safe recommended limit to radium concentration and the annual effective dose of radium in drinking water according to WHO and with other countries.
