In this research, the results of radon concentration, surface and mass exhalation rates, radium concentration, effective dose rate and the alpha index have been investigated in a number of 198 soil samples that have been collected from various residential locations of Halfa Aljadida area, Sudan. The can technique, containing CR-39 have been used. From our results, the average value of soil gas radon concentration was found to be 1.96±0.22 kBq·m −3 . The average values of surface and mass exhalation rates were 1.73±0.19 Bq·m −2 ·h −1  and 34.79±3.87 mBq·kg −1 ·h −1 , respectively. The radium concentration average value was 8.06±0.90 Bq·kg −1 . While the average value of the effective dose rate was recorded to be 54.69±6.11 mSv·y −1 . The average value of alpha index of studied samples was (4.03±0.45)×10 −2 . From the study, a good positive and linear correlation between radium concentration, surface and mass exhalation rates of soil samples were present. In addition to that, a positive and linear correlation between radium and radon concentrations was found. Finally, a comparison between the results and other findings was conducted and the results imply the fact that the area under consideration is safe as if the health hazard are mentioned.
