Abstract: The present study represents the set of measurements for radon concentration levels in ground water using electronic radon meter (RAD7) and for assessment of indoor radon the LR-115 Type II plastic track detectors have been used. The measurements have been taken for the environs and ground water of National Institute of Technology, Jalandhar. The radon concentration in drinking water has been found to vary from 2560 to 7750 Bqm-3 with an average value of 5143.33 Bqm-3. The pH value for the ground water under study has also been measured and it varies from 6.96 to 7.0 with an average value of 6.99. No correlation has been observed between pH value and radon concentration values for ground water. The calculated indoor radon concentration values vary from 74 to 190 Bqm-3 with an average values of 124.50 Bqm-3. The calculated values for the absorbed dose are in the range 1.26 - 3.24 mSv.y-1, which is well below the action level.
