Abstract
Activity concentrations of 20 soil samples were collected randomly from the city central of Al-Diwaniyah, Iraq were measured using NaI (Tl) detector. Estimation of average concentrations of 238U, 232Th and 40K were 15.22, 18.84 and 97.66 Bq kg-1 respectively. The results showed the average value of activity concentrations for 238U, 232Th and 40K were lower than the level reported by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). The radiological hazards of the soil samples were calculated using various models written by UNSCEAR. The radium equivalent activity was found below the permissible limit as reported in Organization for Economic Cooperation and Development (OECD), on the other hand the values of other hazard indices were also lower their limit values. The results have been compared with other location in world.
