[en] Uranium, radium concentration and radon exhalation rate have been determined in soil samples from some areas of Punjab and Tusham (Haryana), using the LR-115 plastic track detectors. 'Can Technique' using these detectors, has been used for the estimation of radium concentration and radon exhalation rate and uranium estimation has been carried out in the samples using the fission track technique. Uranium content in these samples has been found to be varying from 1.03 to 9.96 ppm in the Punjab region and varies from 3 to 13.4 ppm for Tusham region. Radium concentration observed for soil samples has been found to be varying from 0.82 to 8.6 Bq Kg^-1 for Punjab area and from 2 to 9.31 Bq Kg^-1 for Tusham. The Radon exhalation rate in these samples has been found to be varying from 1.2 to 8.83 mBq Kg^-1h^-1 for Punjab area and from 3.11 to 11.54 mBq Kg^-1h^-1 for Tusham. A positive correlations with (R2 =0.61) and (R2=0.60) have been found between radon exhalation rate and uranium concentration in the samples from both for the Punjab and Tusham regions respectively.
