The level of natural radioactivity in soil of 20 mining samples collected from locations in Missan, Iraq. Concentrations of radionuclides in samples were determined by using NaI(Tl) (3x3). The obtained results of specific activity (Bqkg^-1) for each radionuclide in every soil sample and compared with the worldwide average and permissible limits as recommended by UNSCEAR 2008. The values of specific activity for ²³⁸U have been found to lie in the range of 14.6±2.32 to 41.08±2.55 Bqkg^-1 with a mean value of 21.19±2.33 Bqkg^-1, the values of specific activity for ²³²Th 7.88±0.47 to 16.06±0.48 Bqkg^-1 with mean value of 9.72±0.47 Bqkg^-1 and the values of specific activity for ⁴⁰K from 372.67±4.53 to 667.83±6.01 Bqkg^-1 with a mean value of 453.91±5.58 Bqkg^-1. The average values of Ra_eq, AD, AED (indoor and outdoor), H_ex, H_in and (I_γ) were 66.55±10.61 Bqkg^-1, 34.58 nGhy^-1, 0.169 mSvy^-1, 0.042 mSvy^-1, 0.189, 0.2825 and 50.27. It can be concluded that the study area is safe radioactive except for some samples were found high activities need to be further studies.
