In the present study, sealed “can technique” using solid-state nuclear track detector (LR-115) films was employed to measure the radon exhalation rate and radium concentration in soil samples of Cauvery river environment. The mean values of radon activity, radon surface exhalation, and mass exhalation are 216.15 Bq m−3, 521.08 Bq m−1 h−1, and 247.21 mBq kg−1 h−1, respectively. The radium activity concentration and radon exhalation show good correlation.
