Abstract: 

Radon has become one of the major problems in radiation protection since it cause lung cancer. It is radioactive, odorless, colorless, water soluble and the heaviest noble gas. Since rocks and soil contains radium that decays to form dissolved ²²²Rn which dissolved into underground water and surface water. The concentration of ²²²Rn in underground water depends on the concentration of its parent ²²⁶Ra in the underlying rock. In this study, the result of systematic measurement of activity concentration of ²²²Rn in ground water along the coastal regions of Chennai City is discussed. The ²²²Rn concentration in water was measured using the radon emanometry method. The associated effective doses were computed.
