32-36 of Natural Radioactivity of Soil Sample in Selected Locations of Basrah Governorate

Abstract The concentration levels of 226 Ra, 232 Th and 40 K in soil have a great concern in the recent decades, due to its effect on the human health. The radioactivity of some soil samples taken from selected locations in Basrah Governorate have been measured using a NaI(Tl) detector based on gamma ray spectroscopy. Radium equivalent activity, external and internal hazard indices associated with the natural radionuclide were calculated to assess the radiation hazard of the natural radioactivity on the occupiers. The present investigation shows that the level of natural radioactivity for Ra is higher. From the analysing the results, it was found that soil in the area does not possess any health hazard to the inhabitant
